GIF--Figure 1
Figure 1. Outline of northern Great Plains study area. Inset shows position of study area on North American continent. Study area boundaries are as follows: north--border between United States and Canada; east--eastern edge of Missouri Coteau (modified slightly from Fenneman 1931); south--Keya Paha River, Niobrara River, Nebraska Sandhills, and South Platte River; west--western edge of Great Plains as mapped by Aandahl (1972). Areas (in black) within study area were not sampled (see text).
