Raven Maps are beautiful examples of shaded-relief wall maps that display the elevation of a state in vibrant colors. These large maps look great in a classroom, den or office. Use one to mark the locations of your work or company.
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.
“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.
The folks at MyTopo.com are now printing TopoPhotos. They are aerial photographs with contour lines and topographic map annotations lightly superimposed. They give you the advantages of an aerial photograph but also include the elevation, road and place name details of a topographic map. You can use their website to order a TopoPhoto centered anywhere in the United States and have it printed in a variety of sizes in either landscape or portrait orientation. You can print them up to a huge 8′ x 5′ (or 5′ x 8′) in size.

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.
