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

The park is a 6,695 acre regional recreation area, nestled in the hills east of Gilroy, CA, and features a 449 acre lake for fishing and boating. The park provides habitats for many species of birds, reptiles, amphibians, insects and mammals. The park is home to rare western pond turtle, California tiger salamander and Bay checkerspot butterfly. Two-Hundred-Nineteen species of birds have been seen, including our “National Bird” the bald eagle. During your visit you can also be sure to see black-tailed deer, and turkeys. Visitors can explore over 33 miles of trails that wind through cool oak forests and along breezy ridgelines with wonderful views.

About the Map

The Harvey Bear Ranch & Coyote Lake map was made by Matej Šebo for 2012 Golden Goat. The map has been revised and expanded for other BAOC events.

The map will be printed at a 1:12,500 scale on 22”x17" paper. The contour interval is 5 meters.

Most of the park is open land (mapped orange) with some forest (mapped white). Vegetation boundaries are reliable and detailed. Large lone trees are mapped with the hollow, green circle symbol; small lone trees and bushes are shown as green dots. Brown ×'s are fallen trees, green ×'s are dead trees that are still standing.
