Medano Creek

One of the country’s top 25 beaches is here in landlocked Colorado in Great Sand Dunes National Park. Medano creek appears every spring as snowmelt runs off the Sangre de Cristo mountains. As it flows into the valley, the water forms deep ripples in the creekbed, sand dams which stand against the flow until water pressure breaks them every 20 seconds or so. Each one sends a wave down the creek. In a wet year, waves can be as much as a foot high! Medano Creek in May looks like a typical ocean beach. People build sandcastles and frolic in the clean, fresh waves. But the creek dries up by August. Medano Creek is more than recreation. It washes wind-blown sand back down to the valley floor and that maintains the size and shape of the tallest dunes in North America.
