1979 Map of Swain Mountain

USGS Topo · Published 1995

About this map

Lassen National Forest terrain dominates this high-country landscape, where the volcanic topography of the southern Cascades creates a complex network of meadows and seasonal drainages. The Susan River originates in the northern section of the sheet, winding through Clover Valley before reaching Lake Norvell at Norvell Flat. This area serves as a critical hydrological junction, where waters flow toward both the Great Basin and the Sacramento River watershed. Significant landmarks like Swain Mountain and Jennie Mtn rise above the timbered flats, providing prominent reference points for early travelers. The historic Lassen Trail cuts across the northeastern corner, tracing a path used by mid-century emigrants. Land use is evidenced by the Cinder Pit near Clover Butte and the winding Silver Lake Road, reflecting the region's history of logging and resource management within the forest boundaries at the Lassen and Plumas county line.
