1892 Map of Modoc Lava Bed

USGS Topo · Published 1931

About this map

Lava Bed volcanic formations dominate this 1880s-era reconnaissance, capturing a rugged expanse where water and geology define the limits of human settlement. The map documents the complex shoreline of Tule Lake and Lower Klamath Lake before massive irrigation projects fundamentally altered these basins. Notable historic sites such as the Modoc Rifle Pit provide a tangible link to the regional conflicts of the previous decade.
