## About Vallejo White Sulphur Springs

Vallejo White Sulphur Springs is a named spring on the edge of Vallejo in Solano County, less than three miles from town. The water on file is 68 degrees, which is cool tap water, so the sulphur in the name is the point here. Any bathing history is not on record. Who owns the ground is unrecorded.

It is a roadside spring, about a hundred feet off an unnamed road, at low elevation. The climate is mild bay weather, twenty inches of rain in winter and none of it falling as snow. No land unit or manager is listed, and the record does not describe what stands around the outlet.

Winter months are what the record lists as best, which for a spring this cool means the contrast with cold air. No campground is on file within reach. No fee is recorded, and access is blank too, so take a look from the road and ask before walking onto anything that looks private. The temperature is a single reading with no sample date attached.
