J.G.Hall 1952 75 Sagehen Creek, 3 mi. NW Hobart Mills, Nevada Co., Calif. Sept 4 shelf where one was last night. It floated suspiciously for 5 minutes, gradually working upstream before it finally got up enough courage to climb over the small dam at which camera was aimed. I pressed the switch, firing both cam- era and flash this time, when the beaver was in a good position. At the flash, he reacted exactly as (he?) had reacted last night, diving headlong for the same bank burrow. 6:48 the medium size animal appeared at same spot he was last seen, came down to crossing & crossed over into upper pond. Meanwhile the "monster" had also reappeared from his retreat & floated back and forth just above scene of his recent flight as if wishing to go back down to mud shelf. It floated, dove, surfaced, rested on partly sub- merged log and even got to within 3 feet of the dam before suddenly deciding not to risk it again at 6:51 and swam back upstream to cross over into upper pond.
