## About Lava Hot Springs (Thermal Mineral Springs)

This listing covers the Lava Hot Springs thermal mineral springs as a system, the geothermal springs Wikipedia describes in and around the Idaho town of the same name. No temperature is attached to this record, so the page makes no claim about how hot the water is. What is on file is a 1976 chemistry sample with a high mineral load, some iron among it, and a position on Main Street in town. The record places it in Caribou County, with Soda Springs as the nearest city, roughly twenty-two miles.

Main Street runs about seventy feet from the point on record, which is to say the springs are in town. No land owner or public access status is attached to this entry. The climate here is moderate, with winters that are snowy without being extreme and a year that leans dry. Elevation is not recorded.

The springs gave the city of Lava Hot Springs its name, according to Wikipedia, which places the system in Bannock County, Idaho. A USGS thermal site number is attached to the record.

No best season is listed. Pebble Guard Station, about eleven miles away, is the only campground on file. Without a temperature on record there is no heat warning to give beyond the usual care around thermal water. Ownership and access are not recorded here, so look to the city itself for current arrangements.
