This data release includes data collected from the Villa Grove helicopter magnetic survey in northern San Luis Valley and Poncha Pass region in south-central Colorado, USA. The survey area extends over the northern part of Great Sand Dunes National Park, Poncha Pass and vicinity, and into the southern end of the Upper Arkansas Valley. It includes the communities of Crestone, Villa Grove, Saguache, and Salida. Several U.S. Geological Survey programs (including the National Cooperative Geologic Mapping Program, Mineral Resources Program, and Geothermal Program), as well as the Colorado Geological Survey, funded the survey. The data are part of studies to help refine our knowledge in this area about the nature of aquifers,...

This data release includes the airborne magnetic survey data collected from the Manchester region of Iowa. The Mineral Resources Program of the U.S. Geological Survey is tasked with understanding the nation's mineral resources. Precambrian rocks concealed under Paleozoic sedimentary rocks in northeast Iowa are poorly mapped and understood. Detailed high-resolution airborne magnetic surveys, ground gravity surveys, and limited borehole data are being used to better understand the lithology and structure of concealed Precambrian rocks. The primary goal of the airborne magnetic survey is to map lateral variations of magnetization that are related to differences in rock type.
