A Snapshot and The Scoop: The Vanishing Creek

There is a place, deep in the heart of Colorado where towering sand dunes are surrounded by rugged mountain ranges, where water flows above ground only during certain times of the year. Medano Creek borders the dune field at Great Sand Dunes National Park, flowing only when the snow is melting from the slopes of the mountains upstream. Once the snow is gone the creek stops flowing above ground, instead sinking the moisture into the sand while still travelling downstream, surfacing beyond the park in lush wetlands that play host to migrating birds, elk, deer, moose, and bears. Sometimes, during spring and early summer, the creek is cold and deep and fast-moving, stretching all the way from the dunes parking lot to the dunes themselves. During our visit last year Torrey and I followed all that was left of the stream, a little trickle of water, all they way to its end, when it gives up on the surface and soaks into the sand below. In all my visits to the park I've never actually seen the end of the creek - I've only ever seen it full and flowing or completely dry - so this was a fun little sight to see, there at the end of summer.
