2023 Map of Mormon Basin

About this map

Mormon Basin defines this high-desert territory along the border of Baker and Malheur Counties, where the landscape is etched by a complex system of drainage gulches and mining-era nomenclature. The terrain is anchored by significant elevations such as Pedro Mtn and California Mtn, rising above a network of seasonal water sources including Rooster Comb Spring and Mattie Spring. The naming conventions here, from French Gulch and Glengarry Gulch to Puget Sound Gulch, hint at the diverse origins of the prospectors who once worked these slopes.
