## Digital data and derivative products from a high-resolution aeromagnetic survey  of the central San Luis basin, covering parts of Alamosa, Conejos, Costilla,  and Rio Grande Counties, Colorado, and Taos County, New Mexico

#### By Viki Bankey, V.J.S. Grauch, Ank Webbers, and PRJ, Inc.

| This report describes data collected from a high-resolution aeromagnetic survey        flown over the central San Luis basin during October, 2004, by PRJ, Inc.,        on contract to the U.S. Geological Survey (USGS). The survey extends        from just north of Alamosa, Colorado, southward to just northwest of        Taos, New Mexico. It covers large parts of the San Luis Valley in Alamosa,        Conejos, Costilla, and Rio Grande Counties, southern Colorado, and the        Taos Plateau in Taos County, northern New Mexico. The survey was designed        to complement two surveys previously acquired along the eastern borders        of the San Luis Basin over the vicinities of Taos, New Mexico (Bankey        and others, 2004a) and Blanca, Colorado (Bankey and others, 2004b). Our        overall objective in conducting these surveys is to improve knowledge        of the subsurface geologic framework in order to understand ground-water        systems in populated alluvial basins along the Rio Grande. These USGS efforts are conducted in collaboration with other federal, state, and local governmental        entities where possible.
