V. Kemmler 1941 Itinerary May 22, Russian Gulch State Park, Mendocino Co., Calif. elevation 70 feet. There were 5 Peromyscus maniculatus 2 ♀'s and 3 ♂'s, 1 ♀ Sorex pacificus, 3 ♂ Neurotrichus, and 1 ♂ Lepus. May 23, Jean Boulware, Josephine Crowley, Mrs. Gunnell and I set out to explore the trails on the north side of the park. We found that the road in the gulch extends eastward for about 1½ miles beyond the camp grounds and ends in a curve. From this point we took a trail to the falls one mile distant from this point. The trail continued on beyond the falls up the same creek for about ½ a mile and then turned up a canyon and led out onto the Pnie Marrens. There is a road across the Marrens in an east west direction along the fence which marks the boundary to this Park. We followed this west to the top of the north trail. As we passed down the north trail we collected the traps set out from May 21 st.
