1892 Map of Modoc Lava Bed

About this map

Modoc Lava Bed topography dominates this late 19th-century reconnaissance, covering the intersection of Siskiyou, Modoc, Shasta, and Lassen counties. The landscape is defined by volcanic features, including Glass Mt, Cinder Cone, and an Ice Cave, while the northern portion of the sheet shows the original extent of Tule Lake and Lower Klamath Lake before massive reclamation projects altered the regional hydrology. Local history is anchored by markers of the Modoc War, such as the Modoc Rifle Pit and Bloody Point on the shores of Tule Lake, alongside the early cattle-and-timber outpost of Bieber in Big Valley.
