2015 Map of Twain
USGS Topo · Published 2015About this map
The N Fork Feather River carves a deep path through the Plumas County mountains, defining the geography of small riverside settlements like Twain and Virgilia. This portion of the Plumas National Forest is characterized by a high density of named ravines and gulches, reflecting a long history of surface and subterranean exploration. The mining legacy is evident at the Sunnyside Mine near Meeker Bar and the Monitor Mine to the east. Transportation through this difficult terrain is facilitated by the rail line featuring Tunnel Number 26 and several specialized forest roads, including the Greenville Twain Spur. Near the historic settlement of Seneca, the Big Flat Cemetery serves as a quiet marker of the early families who occupied these isolated flats and bars along the river forks.
