Summary:
Nodules of orbicular gabbro found weathered out of rock on the summit of Hiriart mountain were first described by Kunz in 1905, and later by Schaller in 1911. According to Schaller, these nodules measured from 2 to 2.5 inches in diameter and were composed of olivine, hypersthene, hornblende, feldspar, and iron oxides. He also stated that they had a radiating structure. The deposit was covered by the Vanderberg claim. Elevation approximately 1728' AMSL.
