Hot Springs At Sevenmile Hole
Do not enter this water
At 189°F this water is at or above the temperature that causes serious burns within seconds. Springs in this range are frequently vents, geysers, or boiling pools and are for viewing only.
What this number is, and is not
189°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.

Many springs this hot are vents, geysers, or boiling pools meant for viewing only — do not enter. 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.
We can't tell you that, and at 189°F the question is largely settled by the temperature itself: this is above the 104°F ceiling health agencies recommend for hot water. At this temperature water can cause serious burns within seconds, and springs this hot are frequently vents or boiling pools meant for viewing only. Separately, this inventory records no information about land ownership, legal access, or whether a usable pool exists.
