The Sequoia Crest plate. Relief from Copernicus GLO-30; rivers and lakes from USGS NHD; watersheds from the USGS Watershed Boundary Dataset; roads and city limits from Census TIGER 2024.
Sequoia Crest’s center stands about 7,030 ft above sea level. Within three miles the land runs from 3,930 ft to 9,040 ft, a difference of 5,110 ft: mountain country. The highest named summit within 15 miles is Vandever Mountain, about 11,890 ft, 15 miles north.
Under the town center the state geologic map shows Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges) (granodiorite), from the Permian to Tertiary, 2.6 to 260 million years old.
The section below crosses 3 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 2×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Granodiorite. Age: Permian to Tertiary, 2.6 to 260 million years old. About 22 mi of the line.
Schist, gneiss. Age: Paleoproterozoic to Cretaceous, 66 to 2,500 million years old. About 2 mi of the line.
Coarse-detrital. Age: Pleistocene to Holocene, less than 2.6 million years old. About 0.1 mi of the line.

A raindrop that lands in Sequoia Crest reaches the Tulare Lake basin by way of South Alder Creek, the North Fork Middle Fork Tule, the Middle Fork Tule and the Tule: about 80 river miles. The Tulare Lake basin has no outlet to the sea: the water leaves only by evaporating or soaking into the ground.
Lake on the way: Lake Success.
55 miles of the trip are on the Tule.
Often dry. About 50% of the way is mapped as streams that run only after rain or snowmelt; the water makes the whole trip in floods.
