Since 1972 the “Roadside Geology” series has provided introductory information on the geology of states and small regions of the United States.
The books provide a combination of maps, travel logs, photos and commentary for the geology that can be seen along highways or visited at parks and public viewing areas. They are popular with geologists, teachers, students and others who are interested in the Earth.
The Energy Information Administration has published an interactive map that they call their “Coal Data Browser”. It allows you to see statewide averages for variables such as total coal production, total consumption, mine productivity, tons produced per employee hour, sulfur content burned in power production and many, many more. Check it out if you like coal datasulfur-content.gif
“Using a geology-based assessment methodology, the U.S. Geological Survey estimated in-place resources of 1.07 trillion short tons of coal in the Powder River Basin, Wyoming and Montana. Of that total, with a maximum stripping ratio of 10:1, recoverable coal was 162 billion tons. The estimate of economically recoverable resources was 25 billion tons.” Quoted from the USGS fact sheet.
Lots of people enjoy going to fee mining sites where you can prospect inactive surface mines, mine tailings, soil, sediments or outcrops and keep any rocks, gems, minerals or fossils that you find. Examples include: Herkimer Diamond Mines where you can search for doubly-terminated quartz crystals, and Crater of Diamonds where you might be lucky enough to find a real diamond.
You have probably heard of the Richter Scale for measuring earthquakes, the Saffir-Simpson Scale for hurricanes and the Fujita Scale for tornadoes. The Volcanic Explosivity Index is used to compare the size of explosive volcanic eruptions.
The Powder River Basin of Wyoming and Montana contains about 162 billion short tons of recoverable coal from a total of 1.07 trillion short tons of in-place resources according to a new USGS assessment.
The United States Geological Survey has published: New Vitrinite Reflectance Data for the Wind River Basin, Wyoming. “The purpose of this report is to present new vitrinite reflectance data collected mainly from Cretaceous marine shales in the Wind River Basin to better characterize their thermal maturity and hydrocarbon potential.” Quoted from the USGS publication announcement.
“The United States Geological Survey has published: In-Place Oil Shale Resources Examined by Grade in the Major Basins of the Green River Formation, Colorado, Utah, and Wyoming.”
