Sunstone Knoll is a low volcanic rise in Millard County’s Black Rock Desert country where labradorite sunstone weathers from basalt and scoria. Collectors walk the slopes for yellow-to-orange feldspar that flashes in the sun. GNIS places the named summit here (not Beaver County). Stay on public land, avoid active claims, and pack out trash.
