Obregonia denegrii clearly thrives here, but many plants had been washed out of the ground by rain. Charlie Glass tells us that there have been washed out plants every time he has visited the site, and there is serious erosion. Interestingly, someone had made quite an extensive planting of Agave lechuguilla, the istle agave, apparently partly to increase the supply of fibres, but also undoubtedly to help fight the erosion.
Here is a picture of the same species
flowering in cultivation.

with Ariocarpus trigonus,
and Astrophtum myriostigma.
