The U.S. Geological Survey plans a series of low-level airplane flights over the next year that will map mineral resources across four states, including parts of Iowa, Illinois and Wisconsin. A press release states that the flights are a collaborative effort between the USGS Earth Mapping Resources Initiative and the geological surveys of Illinois, Iowa, Missouri and Wisconsin, and are part of a national effort to “map critical mineral resources and modernize mapping of the nation’s geology.” The survey began in November and will take approximately a year to complete. According to the release, the small fixed-wing aircraft to be used will be equipped with sensors and no photography or video data will be collected during the surveys, which will be conducted during daylight hours only.
Planes mapping mineral resources will be in the tri-state area
