This has all the grizzly features of trench foot, or jungle rot, that WWI vets suffered from prolonged exposure to unsanitary conditions and constant wet/
dry feet. Lake Powell Foot is the result of brutal exposure to
mid-summer Utah sunshine, zero humidity, barefoot
10 mile slot canyon
death marches, and days of drunken horse shoes on the hot Lake Powell sand.
Not necessarily a bad thing to have, considering your surroundings.
