Unlike most sand dunes, these are not made of tiny bits of quartz, but of gypsum and calcium sulfate.
Hence the brilliant white, and a texture that is almost like powder.
In steep places, the grains seem to "flow," which helps explain why the dunes aren't very high compared to quartz dunes.
No permanent standing water in White Sands that I know about, Bev.
But a recent rain had dumped enough water in the surrounding higher areas that this low spot took on the temporary status of a very shallow lake.
Elsewhere there was a "river" of sorts that also was very shallow.

Spent 30 days there whilst in the Army back in '85. I saw some the strangest creatures there, and some seriously huge jack rabbits. Just wish I had been into photography back then. Then again, I was more worried about being run over by track vehicles who's drivers couldn't see you parked behind one of those "dunes." Great shots Charlie and thanks for sparking the memory!
There was a Bedouin village there not so long ago. Would have been interesting with a couple camels crossing the sands. My friend was there shooting Transformers II. She sent me a photo with her and a camel. I thought that must be an extraordinary place to photograph. From the looks of it Charlie, I was right. Nicely done.
Very interesting images. Nice job on exposure, also. The whitesand must've been tough to deal with in the sunlight.
I also appreciate the info as to what makes up the sand.
Thanks Dennis and Wayne.
After a few dozen years shooting Kodachrome slide film, I automatically took readings off something about 18% grey, set the exposures manually, and then looked for the shot I wanted. It took longer to write about it than to do it, and the system usually worked okay.
I'm a traveler first- then a photographer- so learning something about the subject is usually an important part of the experience. Well, it is for me .
