W.B. Davis 1935 402 Elba, Cassia Co., Idaho. June 2. armatus up in willows where they probably had been feeding. I have failed so far to take an adult &; all being adult & save for 1 subadult &. All are quite fat. Thomomys quadratus are scarce on this ranch; the cause for this, I believe is too much water. The chief crop is marsh hay which requires a good deal of water and the gophers are limited in areas along the ditches and in one high piece of ground. I took on two occasions an old & and a & in the same burrow system - probably correlated with mating activities. The &'s were certainly in the breeding season. All &'s had 4 pairs of mammae and none contained embryos. June 8 was spent in hiking up Mt. Independence. I got nearly to the lakes and collected few birds - Golden-crowned King let, Cassian Purple Finch Mountain Chickadee and Audubon Warbler & Junco. Saw only two of the lact, although the trip was made specially for them. I saw two mule deer - no antlers - and one Marmot.
