May 30 what appears to be similar environmental conditions?
June 1 .2 miles W of Donna Pass Summit, 8900 ft., Incline Co., Coly. 3 p.m. (D.S.) most of area described by Joe Brown as good habitat is under snow. (See journal for slides taken of area). The dwarf willow growth, however is free of it, and seeps water runs thru the lower areas. The 40° and steeper canyon slope to the S and SE has a full pack of snow probably drifted up to 4' thickness, although a few higher spots are bare. Patches of snow are left up under the ledge side pines to the E. The stem is very high and loaded by thick snow accumulation.
Air temp. 3:32 p.m., look slided, up under scattered pines over line, dry ground 13.2° C. The wind approaches gale velocity most of the time. It has already torn off sheet from my notebook. Wildflowers on slopes have to 3-4". The dwarfed willow is just commencing to burst its buds.
June 3 Mono (?) Meadow, 7100 ft., Y.N.P., Mariposa Co., Calif. 8 p.m. Evening check of at least part of this meadow (1.5 miles E of Peavoy). Plenty of surface melt water covering a third of this elongated (200 yds x 75 yds) section. Slow deep creek runs thru it. Crosses to 8". Dodderstem in bloom, 6" tall. One Rana collected. No amphiuma calls of any kind, yet this appears to be favorable Hyla and Bufo habitat. Mt. chickadee and screech owls heard in pine woods.
