1989 Map of Central Peak

USGS Topo · Published 1989

About this map

The Colville Indian Reservation encompasses this high-elevation landscape in the late 1980s, defined by the sharp topographic relief of the Broken Mountains and the prominent summit of Central Peak. The drainage patterns here are distinct, with Bear Creek and North Nanamkin Creek carving deep valleys through the rugged Okanogan Highlands. The boundary between Okanogan and Ferry counties runs directly through these peaks, following the natural ridgelines that divide the watersheds. This survey captures the area just before the turn of the decade, showing the intricate network of forest roads and trails that connect remote drainage systems like South Nanamkin Creek and Owhi Creek. The map is a detailed record of the natural geography and resource management boundaries within the reservation at this time.
