1950 Map of Boot Mtn

About this map

Colville Indian Reservation lands dominate this mid-century landscape, where the plateau terrain is punctuated by significant volcanic and glacial features. The Columbia River forms a major boundary, showing the river before modern impoundments deeply altered its course. Along its banks, researchers can find numerous navigation hazards and landmarks like White Cap Rapids, Parson Rapids, and Island Shoal. The map captures a moment of transition for local education, noting both active facilities like Duley Lake School and shuttered sites such as Del Rio School (Aban'd) and Ragged Butte School (Aban'd). Settlement patterns are sparse, centered around small hubs like Timentwa and Del Rio, while the Condon Ferry (Site) serves as a reminder of earlier river crossings before the regional road network matured.
