White Sand Dunes National Monument.




This was my favorite part of the trip.
















We hiked the Alkali Flat Trail which is a 5 mile loop. The day was cool and sunny - perfect for hiking on the sand.











The white dunes went on for miles. It was quiet and peaceful out on the trail. Few people walked further than a half mile out.














The sand is made from gypsum. It was very fine and soft. Tahoe enjoyed running on it.











The sand was packed very tightly by the wind, so we had no trouble hiking on either side of the dunes.
















A torrey yucca. I was amazed at the tenacity of the plants which grew on moving sand.
