First digital Alaska geologic map published

The U.S. Geological Survey has released the first ever digital geologic map of Alaska, the agency said Jan. 5. The map provides in a beautifully detailed and accessible visual format a context for the abundant mineral and energy resources found throughout the state - it will provide land users, land managers and scientists with information for the evaluation of land use for resource extraction, conservation, natural hazards and recreation, USGS said.

The map, a completely new compilation of geologic data, builds on knowledge from the past while also reflecting modern geologic concepts. More than 750 reference sources ranging in origin from 1908 to 2015 contributed to the map’s contents. And, being digital in nature, the map and its associated database will enable the creation of a variety of derivative maps and other products, USGS said.

“I am pleased that Alaska now has a state-wide digital map detailing surface geologic features of this vast region of the United States that is difficult to access,” said Suzette Kimball, newly confirmed director of USGS. “This geologic map provides important information for the mineral and energy industries for exploration and remediation strategies. It will enable resource managers and land management agencies to evaluate resources and land use, and to prepare for natural hazards, such as earthquakes.”

“This work is an important synthesis that will both increase public access to critical information and enhance the fundamental understanding of Alaska’s history, natural resources and environment,” said Mark Myers, commissioner of the Alaska Department of Natural Resources. “I applaud the collaborative nature of this effort, including the input provided by the Alaska Division of Geological and Geophysical Surveys, which will be useful for natural disaster preparation, resource development, land use planning and management, infrastructure and urban planning and management, education, and scientific research.”
