Note: this data release is currently being revised and is temporarily unavailable. The Monitoring Trends in Burn Severity (MTBS) Program assesses the frequency, extent, and magnitude (size and severity) of all large wildland fires (wildfires and prescribed fires) in the conterminous United States (CONUS), Alaska, Hawaii, and Puerto Rico for the period 1984 and beyond. All fires reported as greater than 1,000 acres in the western U.S. and greater than 500 acres in the eastern U.S. are mapped across all ownerships. MTBS produces a series of geospatial and tabular data for analysis at a range of spatial, temporal, and thematic scales and are intended to meet a variety of information needs that require consistent data...

Note: this data release is currently being revised and is temporarily unavailable. This data release is a compilation of the locations of airborne geophysical surveys in the United States. The inventory documents public airborne geophysical surveys primarily flown by or contracted by the USGS from 1943 to present. In addition, surveys from the State of Alaska, Department of Natural Resources, Division of Geological and Geophysical Surveys (DGGS): Airborne GeophysWeb, the Bureau of Land Management, the Department of Energy and other state agencies have also been included. The surveys have contributed to studies under USGS programs including Water, Geologic Mapping, Minerals, Energy, Environmental Health, Ecosystems,...

Quartz overgrowths on sandstone grains after clay formation, Nanushuk Group. Quartzose grains have overgrowths at points of low pressure (pore space) adjeacent to areas that were probably under high pressure (grain contacts). Overgrowths probably develop where clay coatings are absent. A polycrystalline quartz grain (upper left) has a pod of kaolinite growing on its surface. Sample 78ACh23, Kurupa anticline; magnification, 6.3 x 10, photomicrograph. Central North Slope, Alaska. Published as Figure 47A in U.S. Geological Survey Bulletin 1614. 1985.

Alaska. Deformation by front action of the wood bridge at milepost 456.7 on the Alaska Railroad in Goldstream Valley near Fairbanks. The cross brace has been split by upward thrusting of the pile. The cap beam has been chopped to lower the track after upward movement by frost heaving. February 11, 1954. Figure 45, U.S. Geological Survey Bulletin 1111-I.

The geochemical data included here were generated as part of the Earth Mapping Resources Initiative (Earth MRI), which was developed by the U.S. Geological Survey (USGS) in response to a Federal directive calling on various Federal agencies to address potential vulnerabilities in the Nation’s supply of critical mineral resources. Earth MRI is a partnership between the USGS, State Geological Surveys, and industry coordinating with other federal agencies to accomplish the mission. The primary purpose of this initiative is to identify potentially mineralized areas containing critical minerals by gathering new basic geologic data about the United States and its territories and to make these data publicly available through...
