Top of ridge had unstabilized rocky talus and crown of mature Jeffrey pine. Total area of site ~250m x 300m, bounded by forest. 25 Museum special snaptraps set at ~10m. intervals in direct line up slope, baited with peanut butter and oatmeal. When possible, traps were set along fallen logs or under pine saplings. Traps 1-17 in manzanita brush, 18-19 in manzanita/talus edge, 20-25 in forest/rocky talus edge. 1 ♀ Eutamias amoenus was found caught in trap #1 when returning down line at 1820. Trap was reset.

N. side of stream had nearby rock field with abundant sign (scat and marking) of Neotoma cinereus. Rick and I set the snaptraps in vole runways when possible, but increasing darkness made it difficult. Jim and several members of the class had set 8 Tomahawk
