High point (9654 ft/2943 m) of the House Range, in the Basin & Range of western Utah. Looking north from Highway 6-50. The cliffs are composed of metamorphosed limestone from cooking by a granite body, the edge of which is just visible on the skyline at left (the pinkish outcrops). Somewhere I saw it asserted that the cliffs here are the tallest in the Great Basin, but I haven't been able to track that claim down. I did a bunch of field work here back in the late 70s. Contact metamorphism of a limestone is a classic setting for tungsten mineralization, so there was a big network of prospecting roads coming in from the east side, which led to better access than you might expect. Dunno whether they're all shut off now, tho--

House Range, western Utah, USA. Looking east. Metamorphosed Paleozoic sedimentary rocks form the cliff, which has been claimed to be the tallest in the Great Basin. The pinkish outcrops in the foreground are of the Jurassic granite that caused the metamorphism.
