Sunset on Round Mountain...


in Castle Valley, Utah this evening (click to enlarge.) This trachyte porphyry stock is an offshoot of the larger laccolithic structures comprising the La Sal Mountains that rise in the background. These resistant igneous intrusive rocks have been exposed by the erosion and collapse of the salt-cored anticline in which the community of Castle Valley is located.

Never mind the details, just enjoy the picture. I'm getting back to my single malt.
