I ran a rectangular magnet over the sand to pick up the mineral Magnetite, a.k.a. Fe₃O₄ or Iron Oxide.

Excellent circle pattern made by a single strand of something blowing in the wind.

Barren wasteland: Dave and Joe head toward the 600 foot dune.

On the way up I saw bird tracks. This is one footprint. This shot also shows the constituency of the sand which is largely rose quartz peppered with magnetite, amphibole, and a host of other minor members.

Dave resting on the dune spine.

Cracks in the sand, probably causes by the added weight of rain water.
