From California 299 at Hawkins Bar (in Trinity County), turn onto the road to Denny and travel 1.7 miles down this road to a fork in the road. Take the lefthand road (leading to Waterman Ridge, Zeigler Point) and travel 6.7 miles down this road to another fork in the road. Take the right fork (away from the road leading to Waterman Ridge and Willow Creek). On this road (7NO4), travel 2.5 miles to another fork; continue on 7NO4 (the left fork) for 7.4 miles. At this point, take 7NO4N, the road to Groves Prairie. The collection site is a short distance up this road.; Groves Prairie
