Water, Water everywhere. . . . .but, where???

Maverick says, "Mile 317.4 on 4/21/13. It appears that we were the first ones to find this water source this year. It was completely overgrown with grasses but we did our best to clear it and make it more visible. We needed this water too! You could barely make out the faintest sound of running water underneath the overgrowth. It's just a small pipe driven into the side of a hill that taps into an underground spring. It would have been a not so fun night if we hadn't found this. I even used this water source to wash some cloths and shower up."
