The RZR's Edge
That's John in his Polaris RZR on the edge of the sink where snowmelt water disappears in Green Basin. The Basin is a huge meadow in the mountains in Cache National Forest, Idaho. As snow melts in spring it flows off the mountains into the basin where it becomes a torrent that drains into these rocks and disappears down a hole. There are limestone caverns in these hills (for example, Minnetonka Cave), so the water may end up in an underground river in one of them. Of course, this time of year the entire basin is dry.
