J.D. Anderson 1958 Journal June 8 Cottonwood Flat, 10 mi. W. Canby, 5500 ft., Modoc Co., Calif. from under look of a dead yellow pine. Worked Craig Springs area for Ambystoma. Will need to come back for some dip net work to be sure there are no Ambystoma larvae in pond before writing this area off. Country looks fine for those salamanders, lots of conifers, good cover & still plenty of moisture. However the ponds are mostly artificial now & there is no way of knowing whether these were ever suitable breeding areas here. All the meadows I have examined thus far are just soggy dryas with no good standing water. Only places I have seen frog tadpoles are in slow moving streams and small artificial ponds - not in meadows. Tomorrow may well tell whether or not this will be successful for salamanders. Left Craig Springs at 11 am & walked back to camp by 12:15 pm. Disappointing morning for hops. Too cool - saw snakes at all. Preserved specimens & put up bait after lunch. Then walked north out of camp following small stream to an aspen grove where I'd heard Hyla regilla. Unable to contact Hyla. Got 3 S. occidentalis, including gravid & ovoviviparous. Found a young Pteromys at edge of aspens. Kept him for a couple of hours for picture. Back to camp for supper. Birds seen so far vicinity of Cottonwood Flat:
