Seep Spring

A seep spring in one of the cliff dwellings of Mesa Verde. It’s a nice shot and others have said they find it very picturesque so I decided to go ahead and put it up.

Explanation:
Rain water seeps down through the soil and more porous rock until it hits a denser layer that it can not easily pass through, it then works its way out along the surface of this dense layer until it finds escape, in this case the side of the cliff.
