When we were in Wyoming, Colby took me on a hike to see this intermittent spring. He described it and honestly, it didn't seem like it would be all that cool, but I went along with it because he was so excited to take me. I must admit now though, that it was pretty neat to see. This spring will be running full force, and then slowly stops completely. The water completely runs dry. The below picture is taken at full force, and the one below that is a wider view of the same area about 5 minutes prior--completely drained. It was crazy cool. So glad I went. Besides the spring, the leaves were just beginning to change and it was beautiful! I love the Rocky mountains!
