About this map

Sierra Army Depot dominates the southern reaches of this landscape, where the arid high desert floor of the Honey Lake Valley meets the rising slopes of the Amedee Mountains. Surveyed in the late 1980s, the map reveals a highly utilitarian landscape marked by numerous Borrow Pits, Disposal Pit sites, and a network of 4WD trails. The rail connection at Herlong (Siding) serves as a primary point of access for this military and industrial area.

To the north, the terrain becomes increasingly complex as it ascends into the Skedaddle Mountains and reaches its height at Hot Springs Peak. This northern section is defined by a series of isolated water sources essential for desert life, including Little Cottonwood Spring and Telephone Spring. The contrast between the organized, gated infrastructure of the depot and the remote, creek-cut canyons like Thousand Spring Canyon highlights the dual nature of this Lassen County border region.
