Summary:

Leslie Gulch Ash-Flow Tuff Member of Sucker Creek Formation of Kittleman and others (1965) has K-Ar age of 15.5 +/-0.5 Ma obtained on sanidine. On basis of mapping by Vander Meulen and others (1987) unit is divided into 3 facies: intracaldera facies, outflow facies, and air-fall facies. All 3 facies were deposited during collapse of Mahogany Mountain caldera.
