Marshall, 1947 Two stops June 21st at the Silver Creek, Eldorado Co., Caly. to "transition forest". Only 1 humit Thrush pewees, Hammonds, Red-Tr. sapwekers, jincos, chippies, robins, And Warblers etc'. It is rather amazing to see Jeffrey Pine forest here on gentle s facing slopes, & Yellow Pine, White Fir, Sugar Pine, Cedar much higher on N-facing slopes. There is not much actual slope around here however. In late afternoon we drove up canyon to Nth for 2 miles thus being in cross valley running N & S on SE side of Robb's Peak. Parked in little str. ravine running E choked with Azaleas in full bloom. The view up this ravine was wonderful - all the trees flanking it were perfect - mature yet with conical tops - no dead ones. Found Solitaries nest with 9 sitting on 3 or 4 eggs on rd cut 1 ft off rd. Hermit Thrushes singing, also Hermit Warblers. This valley had the usual magnificent growth of magnif forest, Sugar Pine, White Fir Cedar, & Yellow Pine. Only 1 Doug fir seen, a giant. Hiked about a mile N to summit of road in large
