This will be a standard event with the full range of courses offered. The standard schedule for registration, starts and course closure will be followed. E-punch will be used for Orange and advanced courses. Maps are 1:10000. Poison oak prevalence in the park is low, but if you are very sensitive, please take precautions. A portable toilet will be available near the registration area.
We have been instructed by the park ranger NOT to cross fences. Hence, crossing a fence without using a gate will be an automatic disqualification. The White, Yellow, Orange, Brown, and Green courses do not encounter fences. If you are on these courses and find yourself wanting to cross a fence, think again. On the Red and Blue courses, you will need to cross the fence several times. A control has been set at each of the gates that must be used to cross.
Map quality is generally poor. There are unmapped and extended trails, and some of the existing trails are not mapped precisely. Boulders are not reliable and contours sometimes require interpretation. White "forest" or vegetation boundary is sometimes just a single tree. However, the map quality should not be a problem for this event since orienteering in Shell Ridge is not technically difficult.
