A S-salt-limestone-gypsum/anhydrite deposit located 11.8 km (7.4 miles) SW of Benavides and 11 miles SW of San Diego. Discovered in 1901. MRDS database accuracy for this location is not stated.

Mineralization is a salt dome deposit (Mineral occurrence model information: Model code: 255; USGS model code: 35a.7 (35ag); Deposit model name: Salt-dome sulfur), hosted in Louann limestone and salt. Local alteration includes biogenic alteration of anhydrock to limestone. The depth to caprock is 389 feet, to sulfur it is 450 feet and to salt it is 500 feet. The salt volume is 3.6 cubic miles to 10,000 feet of depth. Local rocks include rocks of the Goliad Formation.

Local geologic structures include a piercement salt dome.
