In case you didn't believe there are waterfalls at the bottom of the Grand Canyon - this is Hermit Creek Falls. It's the most water I saw (aside from the Colorado River) the whole trip. This small pool generally has more rocks around it and is deeper. The week prior, there had been a flash flood that washed away a lot of the rocks and reduced the size of the pool. Still .. the falls are high enough that you can fit under them and walk into the water to an ankle deep level.
