1979 Map of Swain Mountain

About this map

The Lassen Trail winds through this high-country landscape in the late 1970s, marking a corridor of historical transit across the Lassen National Forest. The map captures a rugged transition between the Susan River headwaters and prominent volcanic peaks like Swain Mountain and Jennie Mtn. Resource and transportation infrastructure is well-defined, showing a Cinder Pit near Clover Butte and the Western Pacific line skirting Norvell Flat, including a section of railroad labeled Abandoned. Water sources are abundant across the terrain, from Silver Lake and Lake Norvell to numerous isolated springs such as Robbers Spring and Barrel Spring, illustrating how the drainage patterns of Robbers Creek and its tributaries shaped the land use of the Lassen and Plumas County border region.
