Appended is the course setter's notes for the Las Trampas orienteering event, please read....
Also, remember that we will have to rent e-Punch devices at the event. Please factor this into your cost. $3.
(Ohh, and I just noticed that compass rental is only $1 so that could be a good choice for those who don't have one)
Even by BAOC standards, the oak and grassland hillsides of Las Trampas Regional
Wilderness can be a little rugged. But that's all part of its charm. And that's
also why we traditionally save this event until sometime during the last two
months of the year, when mild temperatures make the slogging up those slopes a
whole lot easier. We'll also continue another Las Trampas tradition that's
emerged in recent years which tends to keep the wildness down: All courses will
be confined to the lower third of the park south of Bolinger Canyon Road, where
the terrain is much more open and the canyons are considerably less steep than
in the savage forests of the upper two-thirds.
THE COURSES
The "standard 7" courses will be provided. But since only the lower third of
the park will be used, this leaves us with a smaller area than that of a typical
BAOC wilderness event. So we sometimes use this as an excuse to do something a
little creative with some of the courses. This is one of those times.
First, the specs:
COURSE CONTROLS LENGTH CLIMB DIFFICULTY
White ..... 9 ..... 2.4 km .... 75 m .... Easy Beginner
Yellow ... 13 ..... 2.5 km ... 172 m .... Beginner
Orange ... 11 ..... 3.6 km ... 240 m .... Intermediate
Brown .... 10 ..... 3.5 km ... 255 m .... Hard
Green .... 12 ..... 4.1 km ... 345 m .... Harder
Red ...... 13 ..... 5.2 km ... 360 m .... Brutal
Blue ..... 14 ..... 5.8 km ... 405 m .... Abandon all hope
Electronic punching (e-punch) will be provided on all courses.
FOR ADVANCED COURSES ONLY, all utility pole lines and almost all trails will
be left off the map. This will add a bit more navigational challenge to those
courses in a way that we hope will provide some worthwhile map-focus training
for BAOC's "O' in the Oaks '08" A-meet coming up on November 14-16. Since
we've increased the technical challenge, we've accordingly decreased the
physical challenge: All advanced courses will be a little shorter than usual.
Maps for the White, Yellow, and Orange courses will show all trails, utility
pole lines, and other features as they ordinarily would.
SPECIAL NOTE FOR YELLOW COURSE RUNNERS: This course will take you through the
Little Hills Ranch next to the parking lot we'll be using for this event. You
will enter this area through a pedestrian gate next to a larger green gate at
the front of the ranch. You'll exit the area through a gated opening in the
barbed wire fence at the back.
The Yellow course also traverses a small area where the trails are obscured by
a covering of fallen leaves. Don't worry. There will always be a nearby fence,
also shown on your map, that you can use as a guide.
MAP AND TERRAIN
Like all orienteering maps, the BAOC Las Trampas map has its own "personality" .
This map was field checked and drawn by George Kirkov in 2002. Since then, many
of the man-made features, especially fences, have changed quite a bit. We have
corrected the map to reflect these changes in all areas where any course runner
is likely to set foot.
IMPORTANT: The interval between adjacent contour lines on the map is 7.5 meters,
not the usual 5-meter contour interval found on most orienteering maps. Slopes
can turn out to be a lot steeper than they may appear from a casual glance at
the map. Visualize 3 contour lines for every 2 lines you see on the Las Trampas
map and that will give you an idea of how steep the terrain would appear on a map
with the typical 5-meter contour interval.
The terrain is also deceptively rugged in another way: The upper parts of many of
the steeper streambeds and re-entrants actually have sides which are almost
vertical, even though they are not indicated as gullies on the map. Such gullies
are impassable, or passable only with great difficulty. Rule of thumb: If it's
a particularly steep-looking portion of a stream or re-entrant, do not plan on
crossing it.
Green point features are also mapped in a curious style. A lone tree (a single
tree not touching any other trees) can be indicated on the map as a green "X" or
a green "O". The same applies to a distinguished tree (a tree that stands out
clearly from its neighbors in some way).
HAZARDS AND PRECAUTIONS
Because it's autumn and because almost all the trees in the park are deciduous,
many areas are covered in fallen leaves. Since it's hardly rained yet, the
ground underneath those leaves can be fairly hard. All of this, combined with
the steep terrain, is a recipe for "slippery slope". If you intend to run an
advanced course, YOU MUST WEAR CLEATS! Do not attempt to slither your way
around one of these courses in old running shoes. On the Orange course as well,
cleats or hiking shoes/boots with good traction are highly recommended.
Poison oak is always lurking somewhere on just about any vegetated hillside in
the Bay Area. At Las Trampas, poison oak is present throughout the park in the
forested areas. But it's spread very sparsely and it's alomst always very low to
the ground. The only places where you'll find it in bush form are impassable
areas of thick vegetation shown in dark green on the map. At this time of year,
poison oak has shed many of its leaves, so it's harder to spot but less potent
if you do happen to make contact.
Las Trampas Regional Wilderness is a popular area for equestrians, particularly
the trails that will be traversed by participants on the White, Yellow, and Orange
courses. If you come across a horse and rider, STOP and wait for them to pass.
Do not run past the horse! It might get spooked and throw the rider. ABSOLUTELY
DO NOT run out of the forest and suddenly pop onto a trail in front of a horse and
rider. This is a surefire recipe for disaster.

Go punch 'em!
