“Not to make light of a terrible situation, but I’d get in the water...”
Not exactly sure where in the Mammoth area this is but some of these pools are volcanic heated water. There is no going in. I had a buddy spend six weeks in a So Cal burn unit about 35 years back from falling into one of the heated Mammoth pools.
Not in Mammoth Lakes, on the other side of the Sierra about 50 miles west of there.
