Digital products such as this map would not exist without the geologic mapping of generations of geologists whose work contributed to the small-scale state geologic maps that have been published by most states. We gratefully acknowledge the work of the geologists and agencies that supported compilation of this map. Those agencies include the US Geological Survey and the Washington State Department of Natural Resources. We particularly wish to acknowledge Patrick Geehan, the Bureau of Land Management Project coordinator for the Interior Columbia River Basin Ecosystem Management Project, for recognizing the importance of geology to ecosystem management and for supplying funds to digitize the Washington map.
