Aeromagnetic and complete Bouguer gravity anomaly maps have been prepared for the Maroon Bells-Snowmass Wilderness and additions, near Aspen, Colorado. An extreme gravity low, which may be indicative of mineralization, occurs over the White Rock pluton in the southeastern part of the study area. Modeling of the gravity and magnetic anomalies shows that the Sopris, Snowmass, and White Rock pluton
