Since its earliest days, the U.S. Geological Survey (USGS) has played a critical role in the development of Alaska. During the gold rushes of the 1890s, the USGS encouraged settlement and development of the region by mapping routes to the gold fields. Today the USGS maintains an Alaskan Science Center in Anchorage to study the region’s natural resources, hazards, and ecosystems.
