ELK Aridatum 1956 Journal June 29 Tioga Pass - sunny afternoon but strong cool breeze. Sky clouded up eastern 1/2 of sky late afternoon. Collected '9' adults, recently laid eggs, and a series of "yearling" trout at the pond edge. Single C-60 trapped adult -> recovered on surface, first detected with scintillometer, then seen.

Drove north past Sierra Pass road (State 8 & 395) junction its relatively new State Hwy 89 westward past Heaton Lake to State No. 4. Glenn to Woodfords. Information County Road maintenance station, 3/4 mi. south of Woodfords, as to accessibility of road between Lower and Upper Blue Lakes. Foreman reported it took about 2 weeks instead of usual 4-5 days to get road open to Lower Blue Lake. Heavy rains caused icing of snow piles. We drove State No. 88 SW to Blue Lakes Road. First stop Faith Valley, 7500 ft., a locality where I collected broods larvae a year ago. More found this time. Bero muscosa adults (2) collected. Clusters of eyes (to re-emerge stage) in slow streams. Next stop at woods side pond Christy Valley, 7700 ft - Bero's trouts more abundant than I've ever seen them, breaking edge of small pools and larger pond. Hydra regilla adults collected streamside
