The floodplain of the Rio Grande in the San Luis Valley, with Blanca Peak in the distance.
The San Luis Valley
Medano Creek flowing along the edge of the dunes, where it disappears into the sand.
A rolling dune gathers no moss (or other vegetation), but parts of the Great Sand Dunes have stayed still long enough to become partially vegetated. Here we see a view of the sandsheet shrublands, west of the dune field.
Sabkha wetlands at the "sump" - the bottom end of the closed basin.
Semi-desert shrub-steppe and the San Luis Hills.
Stay tuned for more in part 2 - when we fly over the southern Sangre de Cristo Mountains.
