## About Unnamed thermal spring

Five miles or so from Alturas, this unnamed Modoc County thermal point barely qualifies as warm, running in the low seventies. BLM ground, Black Rock Field Office, listed open. The one water measurement on record, dissolved solids from a spring 1980 sample, came back low, so this is fairly fresh water that happens to be a bit above ground temperature.

The road is close, a hundred and thirty feet give or take, and unnamed in the record. Elevation moderate. Snow runs a bit over two feet a winter, precipitation about ten inches a year, so dry summers and cold white winters. No campground shows up on file, and the BLM land carries no special designation.

Winter gets the top rating on the record, though the water will not warm anyone on a cold day. Roadside, so no walking. A fee? None recorded. The dissolved solids number is from 1980 and no pH was ever measured. Ask the Black Rock Field Office if you need more than the word open.
