Dark basalt volcanic dome rising above Queen Valley inside Joshua Tree National Park—one of the park’s clearest windows into young Mojave volcanism. Hard black basalt weathers slowly against pale monzogranite, and a short Geology Tour Road spur plus a ~1.6 mi out-and-back scramble put visitors on the hill’s lower slopes with wide views across the park’s basin-and-range landscape.
