What this number is, and is not

68°F is the maximum surface temperature measured at the vent during the USGS/NOAA thermal springs survey (1965–1980). It is not a current reading, and the temperature of any pool downstream of a vent is almost always lower.

This page also records nothing about access. Land ownership, legal entry, trail conditions, and whether a usable pool exists are all outside this dataset. Confirm with the managing agency before setting out.

This page classifies a temperature; it does not tell you whether a spring can be legally or safely reached. The inventory carries no information about land ownership, access, trail conditions, or whether a usable pool exists at all — many listed springs sit on private land or inside protected thermal areas where entry is prohibited. Confirm with the managing agency before setting out.
