Poker Flat and the small settlement of Skyhigh occupy this high-elevation landscape in Plumas County, where a network of forest roads and steep ravines traces a legacy of mountain activity. The terrain is defined by dramatic ridgelines and watercourses, including the Downie River and its various forks, which have carved deep features like Gold Canyon and China Ravine. This 2012 survey illustrates the remote character of the northern Sierra Nevada, where names like Mount Fillmore and Stafford Mountain dominate the skyline. Local history and genealogy researchers can locate specific high points like Democrat Peak and Bunker Hill, alongside named flats such as Tamarack Flat. The map provides a precise look at the junction of waterways like Little Grizzly Cr and Big Grizzly Cr, which are central to the drainage patterns of this mountain region.
