Happy Camp’s center stands about 1,100 ft above sea level. Within three miles the land runs from 1,070 ft to 2,950 ft, a difference of 1,880 ft: steep hill country. The highest named summit within 15 miles is Kings Castle, about 7,340 ft, 15 miles south-southeast.
Under the town center the state geologic map shows Paleozoic marine rocks, undivided, unit 9 (Western Klamath Mountains) (melange), from the Devonian to Jurassic, 145 to 422 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 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 12 mi of the line.
Peridotite, serpentinite. Age: Neoproterozoic to Early Jurassic, 175 to 1,000 million years old. About 8 mi of the line.
Slate, graywacke. Age: Triassic to Late Jurassic, 145 to 252 million years old. About 4 mi of the line.
From the USGS State Geologic Map Compilation (Horton and others, 2017), the states’ geologic maps joined at a common scale.
Heights from Copernicus GLO-90 (a surface model: it includes buildings and tree canopy); summits from USGS GNIS; rivers from USGS NHDPlus HR; rock from the USGS State Geologic Map Compilation.
A raindrop that lands in Happy Camp reaches the Pacific Ocean by way of Indian Creek and the Klamath: about 110 river miles.
Traced down the USGS NHDPlus V2.1 river network from the Census center point of Happy Camp; river miles along the main stem, rounded.
