2021 Map of Swain Mountain

About this map

Lassen National Forest terrain dominates this 2021 survey, centered on the high ridges and hidden springs of the northern Sierra Nevada. The small settlement of Norvell sits in the northeast corner near Lake Norvell and Norvell Flat, marking a point of human contact in an otherwise wild landscape. Numerous water sources, such as Robbers Spring, Jennie Spring, and Barrel Spring, are mapped alongside the upper reaches of the Susan River. The geography is defined by prominent peaks including Swain Mtn, Jennie Mtn, and Griffith Hill, while drainage systems like Robbers Cr carve through Clover Valley and Barnes Flat. This map captures the modern forest road network, including Mooney Road (LA 103) and the Clover/Swain Mtn Tie, which provide access to these remote elevations across the Lassen and Plumas county lines.
