Pumice
Walking out in the desert this morning with my little black doggie Inu I picked up a couple of very light, low density rocks.
I am certain that they are volcanic in origin. After doing a little research it sure seems like the proper word to describe them would be pumice.
They probably originated either from the various explosive volcanic mars around Kilbourne’s hole, the West Potrillo cinder cones, or the volcanic activity up around Pena Blanca, which is just south of the Organ Mountains and Las Cruces, New Mexico.
Either way they were clearly ejected far up into the atmosphere and then were blown eastward by the prevailing westerly winds. -
Probably around 20 to 40 miles away (32 km - 65 km).
