The George Creek unit is approximately 11,000 acres located in Asotin County about a half-dozen miles southwest of the town of Asotin. George Creek forms the largest subbasin within the Asotin Creek watershed, but this creek, along with its tributaries Pintler and Rockpile creeks, has no surface flow for the majority of the lower reaches. This unit, including the Smoothing Iron ridge of the former Schlee Ranch, was acquired beginning in 2003 primarily for high quality steppe habitats of sharp-tailed grouse and elk.
