Crystal Hot Springs, near Bluffdale in Salt Lake County, is scalding. The water arrives far hotter than a boiling pot, enough to burn badly on contact, which rules out soaking entirely. The record names no owner and says nothing about access. The chemistry on hand was sampled back in 1958.

Location

Under four hundred feet of walking separates the spring from the road, a bit under two miles from Bluffdale. Winters bring about four feet of snow and this is a wet record for Utah at twenty inches of precipitation.

Keep skin out of this water. At 187 degrees it will scald instantly. The record marks it a short walk from the road and says nothing about fences or permission, so approach with caution. Winter is listed as the best season. The chemistry dates to 1958.

Heat Below
92 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 34% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
