Deposit: The montmorillonite is an alteration product of a perlitic pitchstone. The perlitic bed is underlain by a greenish-gray tuff breccia and overlain by a volcanic flow then a light colored tuff breccia. Montmorillonite exposed in the northwestern 1200 feet of the perlitic bed. Most of exposed bed is a mixture of montmorillonite, perlite and some calcite. Clay is white, fine-grained, and compact. Perlitic bed can be traced for more than 3000 ft, but most of the montmorillonite is in the northwestern half. Some of the clay has high swelling and high viscosity. Prospected by a number of shallow pits dug into the steep hillside ; info.src : 1 pub lit
Development: Prospected by a number of shallow pits. Semiactive; recent mining (1984).
