Event Summary

Wildcat Canyon and the adjacent Tilden Park is a pretty large area with hills, lots of trails and varied terrain like oaks, grassy hills and eucalyptus groves. Using two maps specifically designed for navigation sports, course setter Vicki Woolworth will be treating us to a Map Adventure sure to please any navigation sports enthusiast, whether you are looking for a scenic 2 hr hike in the green hills, or a 4 hr endurance race against some of the best in the West.

New to Map Trekking or Rogaining?

Map Trekking is a “Navigation Sport” that has elements of a few other sports and activities like Trail Running, Fell Running (XC hill running), Hiking, Orienteering and Geo Caching.  More specifically, Map Trekking is a time-based challenge, 2 hrs or more in length, where participants try to score as many points as possible within the time allowed, by visiting checkpoints scattered across a vast, wild landscape.  Participants are free to decide which checkpoints to visit, and in what order.  Typically, a set time is allowed before the start for participants to study the map, and determine their route.  Participants travel on foot and navigate their chosen route using the map and a compass (No GPS allowed except for recording your track).  A late finish comes with point penalties, adding another layer of challenge to the sport.  Checkpoints vary in difficulty and the point value reflects the same, so that easy ones yield a lower point value than difficult ones.  To encourage beginners, course setters typically provide plenty of easy checkpoints near the start and finish location.

Venue / Park Info

Wildcat Canyon Regional Park encompasses 2,427 acres along the Wildcat Creek watershed and the surrounding hills and ridges east of Richmond. Wildcat Canyon is a popular destination for hikers, mountain bikers, equestrians, looking to enjoy it’s 25miles of trails.

Large coast live oaks, bay laurels, and a scattering of bigleaf maples and madrones grow on the park's east-facing slopes., while north-facing hillsides support some beautiful, nearly pure stands of bay laurel, fringed with coast live oak. Moist chaparral of coyote brush, poison oak, elderberry, snowberry, bracken fern, and blackberry grow in thickets high on the north-facing slopes.

In the gorge of bedrock-cutting Wildcat Creek grows a riparian forest of alder, willow, creek dogwood, and bay laurel. The forest extends the length of Wildcat Creek and part way up the tributaries. The west- and south-facing canyon slopes are covered with introduced annual grasses. A few stands of native bunch grasses persist. There are many native wildflower species, which will hopefully be in spring bloom during our event.

Expect to have get some great views of the surrounding Bay Area as you climb the hills of the park.

About the Map

The two maps used for this event have important differences. One is an up-to-date ISOM standard orienteering map (Tilden) of a well visited park, and one is older (Wildcat) with basic vegetation, trails, fences, water features and contours (lots of them) in a park frequented by more cows than people. Both have 5 m contours, but Tilden will be printed at 1:10000 and Wildcat at 1:15000, so watch your step (counting) when you switch between the two.

Green on the Wildcat map can mean anything from open forest to dense thickets. While the latter can be extremely difficult to cross, remember that cows can get pretty thirsty, and if there is water in the middle of the dense vegetation, cows will find a way and so can you if you follow the hoof prints. For control descriptions I have used "road" for paved (asphalt) and "trail" for gravel or dirt.
