Great Sand Dunes NP
Medano Creek runs at the edge of the sand dunes. It flows heavily in the spring due to snowmelt in the mountains. A fun thing to watch is the little surges of water that come down the creek every few minutes. It happens when sand grains build up slowing down the water. When the build up breaks down, water surges. The little surge is visible in this photo.
