Wm B Richardson 1935 Thomys bottae young grass plants which had been taken into the burrow in entirety. The soil in most cases is of a fine sandy nature but sometimes it is mixed with coarse bits of graphite or bits of wood or other refuse that has evidently been washed in with the sand or collected there from the near by oak grove some two. Don caught 3 gophers on the shelf of the north facing canyon wall 200 ft above camp. He stated that the soil and vegetation is the same as to be found along the river but it's in a larger area with a greater quantity of graphite in the immediate lava. There is estimated that there is 30 acres of gopher land suitable for gophers on this shelf. Dec 23 Don Tapper took 3 gophers today from the same area as the 6 caught yesterday. Dec 24 Caught 1 gopher from along the river this morning. Habitat is the alluvial flats along the river which has become vegetated with grasses and oak (Quercus wickiupis) Continuing notes are in the Museum of Nat. Zoology.
