May 1973 Journal 32 Colusa Co., Calif. trip walked a few ft when heard a Crotalus (virides?) in front of me. probably at base of brush ~ 3-4 ft away. Left immediately & didn't bother to go Stony Creek again. Returned to Stonyford and drove back into forest via 18N01 to Mill Creek campgd (near Ford Springs) to stay for night. Was ~ 5 P.M. Walked down to Mill Creek (which flows past campgd) and Lo! there were frogs - lots of them. Found egg masses; caught 2 (see species acct's - Rana boylii). Camped there. May collected along Mill Creek for 2 hrs Sunday AM (see species acct's). Drove up to North Fork campgd, turned & stopped at Red Lake Bridge. Walked up Mill Creek a few hundred feet - did see 4 frogs but not collected. Decided was time to go home (~12:30 PM PDT) so returned via 18N03 -> 18N01 to Stonyford - back to Maxwell & rto 5 -> rte 505 -> rto 50 to Berkeley.
