Rough Rocks share similar coloring but different values of the same texture. These two somehow belong together. One too jagged the other barely.
Rough rocks from my collection! The first one (above) is from my trip to Chaco Canyon. I don’t remember where I found it but it reminded me of a chunk of broken concrete. It might be.
This one is from the campus of BYU. More specifically the Museum of Art courtyard. Even more specifically from the cobble-y stone walls surrounding the courtyard. I might have found a loose one between mortar and more rocks and took it. Oops?
