An opal deposit on the north side of Gooch Table, originally discovered by Leah Brashear, Michael Ford, and Chris Wentzell in 1994-1995. Named for the original 7 individuals who were to be owners, including Brashear, Ford, Wentzell, Gottschalk, and others.
Subsequently located by Brashear and others as a mining claim; however the claim was subsequently voided and closed by the BLM as the location is within an area withdrawn from mining location and closed to mineral entry.

| Pliocene - Miocene 2.588 - 23.03 Ma ID: 2775925 | Younger tuffaceous sedimentary rocks Age: Neogene (2.588 - 23.03 Ma) Stratigraphic Name: Horse Camp Formation; Esmeralda Formation; Belted Range Tuff; Timber Mountain Tuff; Paintbrush Tuff; Crater Flat Tuff; Muddy Creek Formation; Siebert Tuff Description: Tuffaceous and other young Tertiary sedimentary rocks. Most of these rocks are sedimentary with a strong volcanic component - a few are tuffaceous with a strong sedimentary component. This unit includes rocks originally mapped as the High Rock sequence in Washoe County; the Horse Camp Formation in northern Nye County; the Esmeralda Formation in Mineral and Esmeralda Counties; older lake beds in Lincoln County; the Belted Range Tuff; the Indian Trail Formation (now abandoned); Timber Mountain, Paintbrush, and Crater Flat Tuffs; Wahmonie and Salyer Formations in southern Nye County; the Siebert Tuff in Esmeralda County; the Muddy Creek Formation in Clark County; and the Thousand Creek and Virgin Valley “beds” in Humboldt County; and other unnamed units. It corresponds to units Ts3 and Tts from the 1978 State map. It is present in all counties.
