A couple of canyons down from us were some Indian ruins called Defiance House. In years past, the water level was a short hike below the ruins. Knowing the water level was a bit lower, we took our tennis shoes. (Or, in my case, my chacos.) Sure enough, the water was low enough that we had to walk off to the right a bit to get around the trees surrounding the channel of water. And by "a bit" I mean, it added about 30-45 minutes of walking on hot sand and rock and backtracking because there was no marked train onto our hike.) We were smart and decided to go during the hottest part of the day.
Here are the ruins.
Monica and Teresa were exhausted by the time they got to the top. (Did I mention that we were smart and left our water in the boat?)
They continued to be exhausted, even after they got to swim back to the boat while the rest of us took that ridiculously hot hike back.
I think Kessa can say what all of us were feeling.
