About this map

The San Andreas Fault cuts a diagonal line across this portion of the Carrizo Plain, marking the geological divide between the flat valley floor and the rising heights of the Temblor Range. This arid landscape is centered on the small settlement of Simmler, where a dense grid of named trails and roads like Belmont Trl and Clements Trl crisscross the basin. To the south, the terrain descends toward the seasonal basin of Soda Lake, a prominent endorheic feature that dominates the local hydrology.

The map reveals an intricate network of specialized transport routes, such as Chowchilla Trl and Caliente Trl, which speak to the historic ranching and land-use patterns of this remote interior valley. The presence of Thompson Spring highlights the critical importance of isolated water sources in this rain-shadow environment, while the county line between San Luis Obispo and Kern counties bisects the northeastern corner of the survey area.
