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--
