Alturas stands as the central hub of this northern California landscape, situated at the junction of U.S. 395 and U.S. 299. The map details a region defined by high volcanic plateaus and expansive basins, where the Pit River drainage system meets the high desert character of the Modoc Plateau. To the east, the steep rise of the Warner Mountains separates the central valley from the distinct, enclosed drainage of Surprise Valley, which contains the massive ephemeral beds of Upper Lake, Middle Alkali Lake, and Lower Lake.
