Patelka 1946 June 23 Southern Washoe and Ormsby counties, Nevada. immediately to the east of Steamboat Valley. The island of yellow pines with on NE slopes of Steamboat scattered pinons around its periphery provides a stepping stone, if not suitable breeding habitat, between the two main ranges. South of the Virginia Range, the gap separating that range from the upper end of the Pin Nut Mountains is small, and although it is cut by the Carson River, scattered pinons occur in the gap. The Virginia-Pinon Nut mountain axis would appear to permit free interchange of individuals in north-south direction. Along the west side of the Washoe Valley, yellow pines occur to the base of the slope. There are willow thickets and manzanita locally, and Aphelocoma occurs in certain areas at least, even though there is no pinon-juniper for miles to the north, south, or east. F. Richardson has observed Aphelocoma along a stream above the home of R. G. Miller near Franktown on the west side of the Valley. I have one juvenile specimen from the northern end of Washoe Valley sent to me by Richardson over a year ago.
