ELKahstun 1955 Bifur Caurus Oct. 22 Tioga Pass - 11:10 A.M. Jim Anderson got a hot spot with Tricalor 40 yards N of tree (t). First reading about 170-180 c.p.m. but we get a maximum at a few spots ran soil surface of ~200 c.p.m. I get about 50 c.p.s. with scintillometer which probably picks up the dirt radioactivity from greater area. Microtues burrow led in under shallow bank 3" below meager grass sod surface. Ran lock about 14 inches before diverging into several surface tunnels. young-of-year toads (3) found in the same about 3" below surface. Animal sluggish but could move. Soil just at saturation point or water could be squeezed from it. toaddlets here surface runs opening Not to scale. 6' all sedge area, Sedges to 16". divide varying 2-3" surface level N running water. Ditch 10" deep air temp. in subsoil run about 2" below surface 3.2°C. Ground surface temp. (b.s.) 9.6°C. at 11:23. Warm sun has been elevating surface temps, probably for several hours but burrow temp. may be similar to minimum of last night. The juveniles may not move for this under to search feel to find retreat. Burbs of breeding scintillate ad pools are
