Explore the wild... Explore yourself!
Preliminary results.
On Sunday morning, 18 March,
36 checkpoints are set in rugged, grassy hills... runners and hikers pore over how
to get them all and get back under a time limit... and then we gather you all up and tell you
to...
Get Lost!! in Black Diamond
Wild Adventure Hunt
A 4 hour and 2 hour
rogaine. On foot. A trek unlike any other!
The Basics, Location, and Schedule
Go solo, or gather a team of 2 to 5 explorers. We'll give you two or
four hours to complete a course that no team can possibly finish. Prioritize and plan
a good route to maximize your point scoring. Or just plan to have a grand adventure!
You'll be using a custom-made map with accurate elevation contours and trails. Find up to
36 or so checkpoints—a compass is recommended to locate the ones off the trail.

Press coverage of our most recent rogaine!
Black Diamond Mines
Regional Preserve was the location of California's largest coal mining operation
between the 1860s and the 1900s. Today, little remains of the coal mining communities. The
Preserve's stark and mostly barren hills present a challenge to intrepid explorers—a
black-diamond-level adventure!
The start and finish will be at the southern end
of Somersville Road in Antioch. From Highway 4, take Exit 26B
eastbound/Exit 26 westbound (Somersville Road) and go 3.7 miles and
park.
We are limited in how many vehicles we can bring to the park. Each vehicle
that brings participants to the event will need to display a parking pass. In
addition, the Preserve assesses a $5.00 fee for each vehicle. So, why not
use a free shuttle that we will
provide from the event headquarters, Road
Runner Sports in Concord?

All the Details!
In this section:
1. Event description
Get Lost!! in Black Diamond is a rogaine. About 36 checkpoints scattered over
the entire Black
Diamond Mines Regional Preserve will be circled on a map and marked on the ground
by orange and white orienteering markers with SPORTident stations which create a
record of your visit on a small electronic card each participant will carry.
Each checkpoint has a point value, which is equal to the checkpoint number rounded
down to the tens. For example, Checkpoint 68 would be worth 60 points. The
objective is to score as many points as you can within the time limit by visiting
checkpoints along your planned route. There are point penalties
for returning late. Maps are issued well before the start, so that teams have time to
plan their route.
At each checkpoint visited, every team member must use her/his
own SPORTident electronic
card to "punch" at the SPORTident station (International Rule B16(a)). To accomplish this by distributing all of a
team's SI cards to one person who goes and punches them all is breaking the
rules.
You may use your own SPORTident card, or rent one from us at no extra
charge.
You will be OK with the smallest-capacity SPORTident
card on the market, unless you plan on getting to almost all, or all, checkpoints.
In this case, we suggest carrying SPORTident Model 6 or Model 9, each of
which can hold 50 or more checkpoint records. We will have a small number of
these available to loan.

3. The terrain
The terrain of Black Diamond Mines Regional Preserve is 19.3 square kilometers
of steep, grassy hills. Most of the area is treeless. There are a few areas of
chaparral, some of which are forbidden to enter. The elevation is 70 to
500 meters, with expansive views of the Sacramento River Delta to the north and
Mount Diablo to the south. There are many roads and trails.
Because of the unusual winter weather, grass is very low and the ground is not
hard. This park has cows, and they may be removed by the day of the event because there
is not enough new grass for them to eat. Cows tend to make ruts and holes in the
ground, so one should be especially careful when running downhill.
4. Potential hazards
The main hazards are steep slopes and heat exposure. As of
now, no parts of the slopes have been marked out of bounds, although one certainly
must exercise caution when going down the steepest ones.
Stay well hydrated—there will be water stations on the
course. Look out for signs of heat stroke in your teammate, such as absence of
sweating, rapid pulse, difficulty breathing, and confusion; if these are spotted,
discontinue your route and head straight to the finish or, if not possible, to the main
park (Somersville) road.
5. Participant safety
Participants will be responsible for their own safety while taking part. Of course,
event staff will try to help you if we learn that you are seriously injured or
otherwise need assistance, but there is a good chance you would be waiting a long time
for help, and we don't have the level of staffing or expertise necessary to quickly
and expertly handle many emergency situations that might arise, so your best bet is to
be very careful not to get injured. If you are not comfortable assuming the risks
involved in prolonged exertion while traveling through rugged terrain under various
and possibly unexpected conditions, then you should not take part in the event.
Each person will be required to sign a liability waiver when registering online or
upon checking in for the event. A parent or guardian must sign for a minor.
The organizers are not in a position to review each participant's preparedness to
participate and will not do so. However, if it comes to the organizers' attention that
a person or a team is poorly prepared for the event, the organizers may deny entry to
that person or team in the interest of the safety of all the participants and staff of
the event.
The team aspect of the event is perhaps the best safety instrument. Team members
must stay together within unaided voice distance, and must
approach checkpoints at the same time. Not staying together will yield
disqualification. If you would like additional reassurance, team up with a friend.
There is cell phone coverage by AT&T and Verizon, somewhat reliable on
ridgetops, intermittent at the start/finish/parking. Participants are advised to carry
cell phones. If there is an emergency, call 911 and also notify the organizers. At
least one of our cell phones will be reachable; this number will be on the front of the
competition map.
If a team has indicated an emergency, it is the duty of all other teams who
are nearby and hear the distress signal to help the team or participant in
distress.
We plan to have a licensed EMT on site, and there is a possibility there will be
additional medical help.
Each team will be required to fill out an intention sheet, which is a copy of the
competition map, with their intended route. The actual route taken does not have to
exactly match the intended route. Intention sheets are due at the briefing
15 minutes before the start.
We will provide water on the course. However, to be on the safe
side, individuals and teams who participate in the 4 hour event should carry
enough water to sustain them for three hours.
The safety bearing is north to James Donlon Boulevard; this will be
noted on the competition maps.
We have a safety, emergency/accident response,
communications, and search/rescue plan you may peruse. Information on this webpage
supercedes the Safety Plan, where contradictory. If you have any questions about
information in this section, please contact our Administrative
Director.
6. The competition map
The map will be 1:20,000 with 10 m contours.
We will offer high-legibility printing. The whole area will be on a single map sheet.
We do not feel that waterproof paper is needed for this event. We will provide plastic
map cases of appropriate thickness.
The source of elevation data for this map is Contra Costa County lidar survey. We
derived elevation contours directly from this data.
The symbols we use on this map are largely the same as those we used on last year's Henry Coe map. Maps will be printed to
magnetic north, and will have a UTM grid (no indication of true
north).
A. CONTOURS: The contours are the most reliable and
consistent component of the map. The quality of the contour base is uniform throughout
the map, and the absolute accuracy is better than ±3 m lateral, ±1 m
vertical. The contours are unaltered by field survey, which could only make them
worse.
B. TRAILS: Trails are from high-resolution aerial photos.
C. VEGETATION: The positional accuracy is better than
±10 m lateral, referenced to the contours or to UTM. In the final version of this
map, all distinct single trees and bushes will be shown, however for this initial
revision vegetation is largely generalized. We use the following grades of
vegetation:
- Open land (white): Most of the map.
- "Normal forest" (light green): Areas with continuous canopy
cover. There are few obstacles to travel in these areas.
- Open land with scattered trees (light green dots): Areas where canopy cover is
not continuous, i.e. ground can be seen in aerial photos. Also fast.
- Chaparral (dark green): Thick, mostly impassable or very slow.
- "Low chaparral" (vertical green lines): Areas of bush/thickets in
which ground is visible in the photo. These most typically/likely contain passable
bushes that are less than waist high.
We use a vegetation boundary symbol (a solid green line) between all areas of
different types to aid readability. This does not mean that all of these boundaries
are distinct. The use of color on this map is not the same as it is on an orienteering
map; all of the vegetation symbols are green or white, to conform to our standard for
wilderness maps.
D. STREAMS: The streams are from USGS 7.5' quad data.
E. ROCK AND FENCES: We didn't show rock, but put down fences
that were obvious in the aerial photo, in particular these that comprise the park
boundary.
The official park map has true-to-life trails, and can be useful for
pre-event preparation.
7. Course specifics
There will be about 36 checkpoints, totaling 1000 points. The optimum
distance to get them all and to stop at all water stations will be
between 28 and 30 km along straight lines. Climb on this route will be
between 7% and 8% of the actual distance traveled.
The number of points awarded for visiting a checkpoint is the first digit of the
checkpoint's code, times 10; for example, Checkpoint 68 is worth
60 points. The penalty for being late is 10 points per minute, or fraction
thereof. Teams finishing more than 30 minutes after the deadline will be
disqualified and will get a score of 0.
Most locations are technically quite easy. We will assign values to checkpoints
based on their combined navigational and physical difficulty. In other words, don't
expect a gimme from a 50-pointer.
Other than the start/finish, there will not be aid stations on the course, manned
or unmanned. There will, however, be unmanned water-only stations (below).
The start/finish will feature an ample supply of energy gels by . PLEASE DO
NOT LITTER IN THE PARK!!!! If you do, this event may never happen
again.
There will be two or three water stations. These locations will not be at
checkpoints, and will not be worth any points. Plain bottled water will be
offered, in individual bottles or in jugs.
There will be a trash bag at each water station. You are allowed to dispose of
your trash into these bags, but not elsewhere on the course other than the
start/finish. There will not be any other drinks, food, or supplements at the water
stations.
Each checkpoint will be equipped with an orange and white orienteering control
marker and a SPORTident electronic
station. There will not be sign-in/intention sheets at checkpoints. Water stations will
not have orienteering markers or SPORTident.
The orienteering marker may have a number/code that will not match the checkpoint
code. The correct code is shown on the SPORTident station. To punch, put the
SPORTident tag through the opening. If there is no confirmation beep nor a light
flash, use a paper punch attached to the control marker to punch your map. If you are
unable to find the checkpoint but think you are in the right location, take a picture.
All locations will have been verified with GPS.
All team members must punch the SPORTident station within 60 seconds
(first to last) in order to claim credit for the checkpoint.
8. Classes and categories
There will be two event divisions, the 4 hour and the 2 hour.
Solo competitors and teams are allowed in each of the two divisions. The maximum team
size is 5 members. A team that has a member born after 1998 must also have a
member born in 1994 or earlier.
There will be the following gender classes:
A mixed team is one that has members of both genders.
There will be the following age categories:
- Open;
- Juniors (each team member born in 1992 or later);
- Masters (each team member born in 1972 or earlier); and
- Supervets (each team member born in 1957 or earlier).
Every team is eligible for awards in the Open category. Some teams may fall into
multiple age categories. In this case the team is eligible for awards in all
categories in which they meet the criteria.
Logical combinations of the above classifications will constitute awardable
categories, for example, "4 hour Supervet Women" or "2 hour
Junior Mixed". Categories with few teams will not be consolidated for the
purposes of awards.
9. Scoring, results, and awards
All teammates must stay within unaided voice distance and all must punch at a
checkpoint in order to claim credit, within 60 seconds (first to last). If one team
member is unable to continue, the whole team must report to the start/finish. A new
team may be formed and it may then go on the course, but it will be unable to claim
credit for checkpoints already visited.
The number of points awarded for visiting a checkpoint is the first digit of the
checkpoint's code, times 10; for example, Checkpoint 68 is worth
60 points. The penalty for being late is 10 points per minute, or fraction
thereof. Teams finishing more than 30 minutes after the deadline will be
disqualified and will get a score of 0.
Teams will be ranked within their division, age, and gender categories according to their total score. Among teams with
identical scores, the earliest finishing team will be ranked highest. Teams that are
disqualified or do not finish do not get a place.
(Every team that finishes within 30 minutes of
the time limit, and does not break certain rules, gets a score.
You don't have to stay out for the full 2 or 4 hours! You can finish earlier
if you feel like it.)
Upon finishing, teams should proceed to a SPORTident download station. Points will
be tallied, and each team will receive a copy of their score sheet that will contain
checkpoint-by-checkpoint split times, the total straight-line distance traveled, and
the approximate climb.
Top teams in all divisions, classes will get prizes from our . Event results, splits, and RouteGadget will be
promptly made available online.
10. Weather and recommended clothing
"Late winter" in inland Bay Area can assume a range of shapes. Sustained
rain is possible, as is sustained sunshine. It cannot be too cold; the recorded lows in
Antioch in March never dropped below freezing. It can, however, get in the 80s (above
+27 °C). The average high is +22 °C (71 °F) and the average
low, +8 °C (46 °F).
We will have tents erected, but there are no shelters or heated indoor facilities at
the parking/start/finish. These are available at the visitor center, about
0.9 miles (1.4 km) from the start/finish.
11. Parking
We are limited to about 40 participant vehicles, and will implement capacity
control and a shuttle from Road Runner Sports in Concord. Parking fee at Black Diamond
Mines is $5 per vehicle, payable in cash to the park. On top of this fee, each
participant vehicle is required to obtain a parking pass from us; this pass also
costs $5. This levy was agreed upon as a condition of us holding the event so as
to not overcrowd the limited parking, leaving room for regular park users; the parking
lots typically fill up on a good-weather March weekend even without a special event
going on. The parking pass will be e-mailed to the team upon payment for its
registration.
The shuttle will make a single trip from Road
Runner Sports according to the
event schedule. There will be a single return trip after the end of the
4 hour rogaine. The shuttle capacity is between 40 and 50 people; no
advance reservation is required for the shuttle.
12. The rules
Orienteering USA
Rules for Rogaine Competition and the International Rogaining Federation Rules of Rogaining will be in
effect, supplemented by this information. When there is a conflict between the two
sets of Rules, U.S. Rules take precedence.
Here are a few rules highlights:
- Team members must stay together (within unaided verbal contact) the whole time
they are on the course (Orienteering USA Rule 5.5).
- All team members must go to each checkpoint visited by the team, meaning all
must punch within 60 seconds (IRF Rule B16). (This rule is why
each team member must carry a SPORTident card.)
- All participants are required to respond to a distress signal and to assist a
participant who is injured and needs assistance (Orienteering USA
Rule 10.2).
- All participants are responsible for their own safety while they participate,
and participants should make themselves aware of the hazards associated with the
weather, rugged terrain, health risks of extreme exertion, equipment malfunction,
and remoteness from emergency assistance.
- Except in case of emergency, all participants must check in with event staff
before leaving the area; in case of emergency, an evacuated participant or her/his
team members should notify event staff of the situation as soon as possible after
attending to the emergency.
- Points will be deducted from the scores of late returning teams, and teams
finishing more than 30 minutes late will receive a score of zero
(Orienteering USA Rule 9.1).
- A team may be disqualified for infringing these rules
(Orienteering USA Rule 8.1).
- Solo participants are allowed in all divisions (exception to
Orienteering USA Rule 3.1 and IRF
Rule B1).
- GPS devices and altimeters (such as GPS tracking watches) may be
carried on the course (to allow tracking analysis afterward) but not used for
navigation by teams. If carried, any such devices that have a display must be
presented to race officals to be sealed (after tracking is activated, if desired)
before the start. Without going into the details of the sealing method, we can say
that participants with GPS watches and altimeters should plan to carry them, not
wear them. This is an exception to Orienteering USA Rule 5.2
and IRF Rule B7.
The required equipment is (we may modify this list up to one week before the
event):
- Each team must have bottles or other containers able to carry at least
0.5 liters of water per team member.
- Each participant must carry a whistle for signaling in case of emergency
(three short blasts).
- Each team must have a watch, or another time-telling device.
- Each individual must have a SPORTident card.
We will check this equipment before the start. Teams who do not possess it will
not be allowed to start.
13. Suggested equipment
Each team should have a cellphone (AT&T or Verizon); a compass; clothing
appropriate to the weather, accounting for the possibility of injury or exhaustion;
shoes with treads appropriate for the steep slopes; food/energy snacks; a first aid
kit; and a space blanket. Salt tablets are advised for 4 hour division
participants.
Travel and Accommodations
The directions to the start/finish are here. Public transit will get you to the event headquarters, and BART will deliver you within easy biking distance of the
start/finish.
Orienteering USA has negotiated discounted rates with its sponsor, Motel 6.
The closest Motel 6 property is in Pittsburg. At the time of this writing, members of
Orienteering USA were offered rates as low as $41.39 per night, plus tax. In order to
get these rates, you must book through the Motel 6/Orienteering USA partnership program. By making
your booking through this website, you will be supporting U.S. orienteering and
rogaining.
Entry and Registration
We have a limit of 70 participants.
This event will sell out. There will be no waitlist.
We will offer tech shirts with this design to the first 50 individuals and
teams who enter. All food during and after the event is included in the registration
price.
Pre-registration is open. Team members may enter together
(be entered by the same person), or separately. If you would like to go with a team,
but don't know your teammates' names yet, you can enter yourself and other members can
join the team at a later time.
As with all events by Get Lost!!, fees for teams are capped. Three, four, or
five people enter at the team price; each team member gets a map. The price for a team
is determined when the last member joins it; additions after the deadline will increase
the team fee. The fees are:

her/his size. Because of the lead time involved in printing the shirts, it is not possible
for us to provide shirts to late-entering participants.
Extras!!
Please add $5.00 if you would like a parking pass for one vehicle at Black
Diamond Preserve. Up to two passes can be ordered per team. There is a separate parking
fee of $5.00 per vehicle, payable in cash to the park upon entrance.
Discounts!!
On top of these prices, we offer the following discounts:

The BAOC and Orenteering USA discounts only apply to
individuals, not teams. For example, a registration for two people who are both BAOC
members will cost less than the team price. A three-person team is always best off taking
the team deal.
These discounts are taken and combined automatically by the registration system.

Event-Day Information
1. Safety
A. IN CASE OF EMERGENCY
If there is an emergency, call 911 and also notify the Administrative
Director. Contact info is on the front of your map.
B. REQUIRED AND SUGGESTED EQUIPMENT
REQUIRED: Bottles or other containers able to carry at least 0.5 liters
of water per team member; Whistle; Watch; SPORTident electronic tag (ONE PER
PARTICIPANT).
SUGGESTED: Cellphone (AT&T or Verizon); Compass; Appropriate clothing
and shoes; Salt tablets; Food/energy snacks; First aid kit; Space blanket.
AID: Two water-only stations on the course with plain bottled water.
C. HAZARDS
STEEP SLOPES: If we thought it's not safe, it's marked out of bounds
on the map. Shoes with a good tread are helpful.
HEAT EXPOSURE: Stay well hydrated. Look out for signs of heat stroke in your
teammate, such as absence of sweating, rapid pulse, difficulty breathing, and
confusion.
D. TIME LIMITS
2 hour event: 12:30 pm
4 hour event: 2:30 pm
E. INTENTION SHEET
Each team and individual participant must mark their intended route on a copy of the
competition map. This so-called intention sheet will be collected at the briefing
15 minutes before the start. Teams and participants who do not provide an intention
sheet will not be allowed to start. It is not critical that the team follow this plan,
however the intention sheet will give us a good idea where to look for a team should it
become missing.
F. TEAMMATES STAY TOGETHER
All teammates must stay within unaided voice distance and must punch at checkpoints
together in order to claim credit. Not staying together will yield disqualification.
G. SEARCH PROCEDURES
At 02:45:00 pm, that is 15 minutes after the 4 hour time limit, we will
generate a list of teams and individuals who have not reported back from the course. We
will take into account the download information and all cars/shuttles still missing
passengers. We may do so earlier for the 2 hour event. If the list is not empty, we
will first attempt to reach the participants' cell phones and then their listed emergency
contact numbers.
IIf these attempts are unsuccessful, we will retrieve the missing participants'
intention sheets, and use them to narrow down the areas to search. We will first dispatch
spotters to look for the missing person(s) from high points on the ridge. If unsuccessful,
we’ll then dispatch event staff to query SPORTident stations in this likely area. Past
experience shows that these workers are quite likely to discover the missing team(s). If
the missing participants are still not found, the stations will be read out to further
narrow down the search area.
Full-scale search will commence as soon as this information is generated, and will be
directed by the event's Administrative Director or by authorized emergency personnel.
H. CELL PHONE COVERAGE AND COMMUNICATIONS
Cellphone coverage varies for AT&T and Verizon. It is unreliable and/or absent in
the canyons, including the start/finish.
I. MEDICAL PERSONNEL
There will be an EMT stationed at the start/finish beginning at the completion of the
4 hour event.
2. Map, terrain, and course notes
For most extensive map notes, please refer to the map section. Here's the summary, with updates:
- The elevation contours are exquisitely accurate. There are no index contours nor
spot heights shown.
- The trails are accurate. We didn't show all of the cow paths. All of the relevant
info from the official park map is on our map, with the exception of trail names.
You can study the park map beforehand, but you cannot use it for course planning on
site nor take it with you on the course (International Rule B7.)
- Vegetation is shown, but is somewhat generalized. There is some chaparral, which
we have been asked not to enter, and you will be foolish if you do. The chaparral is
not marked out of bounds on your maps, but is marked as chaparral.
- Ponds and some creeks are shown. Rock and cliffs are not shown. Some fences and
most power lines are shown.
- There is a single area (EBRPD corporation yard and adjacent lands) that is out of
bounds. It is marked on your map with vertical purple lines.
- Areas outside the park are not shown in detail, and no checkpoints are outside
Black Diamond Mines Regional Preserve.
The course setters, Bill and Heidi Cusworth, were quite succinct in
their comments: Some of the fences (both mapped and unmapped) are quite strong, and may
slow you down. There is very little poison oak, and the course is quite long (28+ km
along one of the possible routes, straight lines), so no teams or individuals are expected
to collect all checkpoints. There are exactly 36 checkpoints.
We maintain a discussion board for all
our events on Attackpoint. Popular among map and adventure-sports athletes in
the U.S., Canada, Australia, New Zealand, and other countries, the site is the one to go
to for the latest adventure-running news, schedules, discussion, and gossip.
