Kingstley 1980 41 16- 17 Sept 5 mi E and 1 mi N Grapevine Peak 5500 FT. This is approximately one of the locations cited by ER Hall in Mammals of Nevada. Harvey I. Fisher on 2 June 1940 trapped Notiosorex crawfordi here. HE (evidently) also collected Sylvilagus auduboni, Perognathus parvus, P. formosus, Dipodomys microps, Onychomys torridus, Peromyscus crinitus, P. maniculatus, P. truei, and Neotoma copida here. The area is sagebrush community, with pinyons visible on highest hills surrounded and in valley about 1/4-1/2 mile west and 100-200 feet higher. Sagebrush (Artemisia tridentata) is dominant on the ridges and valley here. A valley about 200 yds wide is between two ridges of a least 40 ft elevation above valley. Ridge on S side of valley is very rocky, several rock outcrops and small talus slopes. Other vegetation that was conspicuous included: Ephedra (viridis?) in patches, especially on rocky ridge. Mendota spinicera, Cleophasmus nanus. Weather was partly cloudy, light breeze, comfortably warm. A 1/2 moon set around 9 pm. I set 100 traps Sherman's, oats-peanut butter-bacon grease bait in 3 lines. Forty traps in line on rocky ridge on S side of valley beginning at outcrop nearest road. 40 in valley, 20 in sand-gravel wash. Area has been impacted by cattle - a couple of Purshia in wash have been severely pruned by them. Many cow pies, old and new), fresh tracks. Set traps by 1800 hs.
