Kendall Warm Spring
What this number is, and is not
86°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.

Frequently Asked Questions
Kendall Warm Spring was recorded at 86°F (30°C), which classifies as Warm (86–99°F (30–37°C)). Pleasantly warm and below typical hot-tub heat. That figure is the maximum surface temperature measured at the vent during the USGS/NOAA survey between 1965–1980 — not a current reading, and not the temperature of any pool downstream of the vent.
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.
Kendall Warm Spring is in Wyoming at approximately 43.2820, -110.0190. The nearest graded lake is Upper New Fork Lake, about 13.1 miles away. Coordinates come from the USGS/NOAA inventory and locate the vent, not a trailhead or parking area.
