photo truck delivering caliche

Road (and runway) building in south texas is done with Caliche. Caliche is soil that has had water from limestone aquifers percolate up through and evaporate in, leaving calcium impregnated grainy soil with a few soft "rocks" in it. A neighboring ranch had some abandoned oil drilling pads that were being reclaimed and revegetated. They were looking for a place to dispose of waste caliche. Right here, please, in this strip 18' wide. I got 187 truckloads.
