EL Karsten 1956 Bufo canorus June 30 Upper Blue Lake, 8100 ft., Alpine Co., Coly. - silty. Also located 40 yards from edge of lake. Broods were concentrated near edge of lake, and breeding probably occurs along the grassy margin where streams enter. This could represent ecological separation in preference for breeding sites. However, I would be surprised if some hybrid moties do not occur at this locality. July 30 Paul K. Anderson reports canorus breeding at west side of Saddlebag Lake, 10,051 ft., Mono Co., Coly. on July 29. Some recently hatched embryos. Adults also seen along stream area between Emness Glacier and Saddlebag Lake, about 11,000 feet. The breeding stage suggests a later season. Paul says that there was lots of snow around Saddlebag, chunks falling into the lake. Still some snow along Terga Lake, too, and patches in Pass area.
