About this map

The Nez Perce Indian Reservation Boundary cuts across this 1990 survey, marking a clear division in the high country between Latah and Nez Perce counties. The landscape is defined by the deep drainage systems of the Potlatch River and its tributaries, including Little Potlatch Creek and Middle Potlatch Cr. These watercourses carve through prominent uplands like Fix Ridge and the namesake Green Knob peak.

For local historians and genealogists, the presence of Overacker Cem and Fix Ridge Cem provides valuable points of interest for family research. Small-scale industrial activity is evidenced by a Gravel Pit located near the southern boundary, while the network of unimproved roads and trails suggests a region primarily focused on timber or ranching. The topographical detail follows the descent into Howard Gulch and the winding path of Catholic Creek as it flows toward the main river valley.
