Thacker 1959 Species Account Thomomys monticolus p.3 Oct. 4 (cut) of perhaps 2 or 3 acres surrounded by pines. The grass here is green and v overgrazed by sheep. The soil is moist, clinks and fine. There are a lot of gopher workings here. These animals seem to be relatively common in this meadow. 3.5 mi N, 1.9 mi E Calpine, 4910+ ft. Plumas Co. Calif. I got one of this species from the three lots in the dry stream bed here. The soil is v. gravelly since it is composed of stream outwash.
