From Calif. 99 at Hawkins Bar (in Trinity County), turn onto the road to Denny and travel 1.7 miles down this road to a fork; take the left fork (not leading to Denny but to Waterman Ridge and Zeigler Point) and travel 6.7 miles down this road to another fork. Take the rt. fork (away from the rd. leading to Waterman Ridge and Willow Creek). On this rd. (FD 7 NO4) travel 1.5 miles to another fork; continue on 7No4N (the left fork) for 7.4 miles. At this point, take 7NO4N, the rd to Groves Prairie. The collection site is about 50m to the right near the Groves Prairie Creek sign. The site is 17.9 miles from Hawkins Bar just beyond mile marker 9.; Groves Prairie
