Close up of Quartz conglomerate. See the quarts pebbles mingled in this sedimentary rock?
Wind , water and wear of time cause these rocks to turn loose of the pebbles within their matrix and large holes erode. See how honeycombed this stone is now? Makes for good climbing!
Standing atop the overlook of Black Mountain Summit. Gazing across the rocky surface. The deep holes here are filled with rain water that is lightly frozen.
