A Whatizit? Photo for the Day

A nice little photo "what is it?" for the day. The dark chunks are about a foot across and the location is at the south end of Joshua Tree National Park. I was going through the photo archives of one of my meetings of the National Association of Geoscience Teachers, preparing a post about our roadguide for the geology of the Coachella Valley and surrounding mountains. You can check it out here.
