2021 Map of Upper Centennial Flat

About this map

Upper Centennial Flat and the surrounding high-desert terrain of the Coso Range dominate this recent topographic study. The landscape is defined by its arid geography, where critical water sources like Upper Centennial Spring and Upper Haiwee Spring appear as vital points of interest in a region otherwise characterized by expansive basins and sharp elevations. The map reveals a complex system of drainage and relief, including the steep descents of Centennial Canyon, Lacey Canyon, and Thorndyke Canyon, which cut through the uplifted peaks of Silver Mtn and Pinon Peak. This 2021 survey illustrates the modern configuration of Inyo County's high-altitude flats, such as McCloud Flat and Upper Cactus Flat, situated on the northern edge of the Mojave Desert. The presence of established township lines and sections provides a clear framework for researchers tracing land parcels or geological features across these prominent western landforms.
