Quarterly Coal Distribution Report
(Wed, 02 Apr 2025) The Quarterly Coal Distribution Report(QCDR) provides detailed U.S. domestic coal distribution data (excluding waste coal and imports) for fourth-quarter 2024 by coal-origin state, coal-destination state, mode of transportation, and consuming sector. Quarterly coal distribution data for all quarters are preliminary and will be updated in the corresponding Annual Coal Distribution Report.

How geology and climate control vegetation composition and distribution in the Yellowstone Geoecosystem
Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Cathy Whitlock, Regents Professor with the Department of Earth Science and the Paleoecology Lab at Montana State University. In Yellowstone, geology and ecology go hand in hand. In fact, the geology of Yellowstone can be mapped by its vegetation! For example, the glacial clays in the Lamar and Hayden valleys are rich in nutrients, like calcium and magnesium, and have high water-holding capacity; these qualities favor growth of grassland and sagebrush steppe. These landscapes are called the “Serengeti
