For those willing to venture to Great Sand Dunes National Park without the Alamosa Supercharger Station, Medano Creek was as wide as I've ever seen it yesterday:
More snow than average plus a later than usual melt has delayed peak flow from mid May to late May. The flow was surging as sand dams form and break, which is what Medano Creek is known for. The creek was numbing cold in early morning and rather pleasant by mid morning. By afternoon children are happily playing in the water as it has been heated by the sun while flowing around the dunes. Seeing the creek next to the gigantic dunes with the Sangre de Cristo Mountains behind is well worth doing! You can monitor creek flows on the National Park website.
This is a view of the creek and parking area from 500 feet up the dunes:
Hiking the dunes is best done in the morning before the sand gets hot and the wind picks up. Fair warning: hiking sand dunes at 8000+ feet starting elevation is a workout.
Made it to the top, about 650 feet:
These are the tallest dunes, over 700 feet:
The park rangers said that it is about a six mile hike to the tallest dunes, for those who want to give it a try.
