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.
