The Burnt Ranch 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.
Burnt Ranch’s center stands about 1,490 ft above sea level. Within three miles the land runs from 940 ft to 5,010 ft, a difference of 4,070 ft: mountain country. The highest named summit within 15 miles is Green Mountain, about 6,390 ft, 12 miles east-northeast.
Under the town center the state geologic map shows Pre-Cenozoic metasedimentary and metavolcanic rocks undivided (schist, gneiss), from the Paleoproterozoic to Cretaceous, 66 to 2,500 million years old.
The section below crosses 5 rock units mapped at the surface.
Heights every 0.1 mile from the Copernicus GLO-90 surface model; vertical exaggeration about 4×. The colored band under the surface is the rock the state geologic map shows at the surface, not a picture of what lies beneath.
Melange. Age: Devonian to Jurassic, 145 to 422 million years old. About 14 mi of the line.
Diorite. Age: Jurassic to Early Cretaceous, 100 to 202 million years old. About 7 mi of the line.
Slate, graywacke. Age: Triassic to Late Jurassic, 145 to 252 million years old. About 2 mi of the line.
Schist, gneiss. Age: Paleoproterozoic to Cretaceous, 66 to 2,500 million years old. About 0.8 mi of the line.
Mica-schist. Age: Early Cretaceous, 110 to 143 million years old. About 0.8 mi of the line.

A raindrop that lands in Burnt Ranch reaches the Pacific Ocean by way of McDonald Creek, the Trinity and the Klamath: about 90 river miles.
