EL Kadet 1955 Bufor coronus June 26 turreled numerous logs and dug many rodent burrows. Breeding must have taken place about 2 weeks ago. One yearling tad collected in grass near seepage pool. Pool described by hazy as less than 10" deep. Some toads at margin of cold deeper and most majority in sedge filled shoulder (1-2") 3/4 mile from gravel. 1:50 p.m. we continued our work to Highland Lake 2 1/2 mi S Elbert's Pass, 8000 ft, Colgan Cr., Colo. Dense concentration of tadpoles in seepage pockets in meadow. It looked as if I laid the eggs in these two depressions only 3' 4" 8-10" 3' the intervening and adjacent pockets have no larvae at all. Daylight (no x.) <2". Temp. 2:15 p.m. 29.2 C. 1" below surface. Tadpoles total length about 12-13 mm. Seepage flows over sedge and wild onion covered ground. Willows, corn lilies abundant. Willows have between depressions (cattle or horses) to 6-8" high. Toads in smaller depression must number close to 1000. Horses found at a half dozen localities in this area (250 yds. square) meadows but no eggs. Hatched out larvae are very close in size, varying from 10-18 mm. But that range can be found in one group. Average size of those seen down & 14 mm. which is rare 4-5 mm. smaller than expected.
