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.
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.

“The next big earthquake on the Seattle fault could trigger destructive landslides in the city, potentially affecting a much larger area than previously thought, and in areas outside those currently considered to be landslide prone.” Quoted from the University of Washington press release.
“The use of hydraulic fracturing has unlocked vast new reserves of natural gas. Now Alta Rock, a startup based in Seattle, is developing technology that might do the same for geothermal resources, turning a marginal power source into a major source of carbon-free electricity and heat.” Quoted from the MIT TechnologyReview.com article.

The geographic distribution of scientists and engineers in the United States is not uniform. Some states have much higher percentages of these professionals than other states. Virginia, Washington, Maryland and Colorado have higher than average numbers of these professionals. Arkansas, Kentucky, Louisiana, Mississippi, North Dakota and South Dakota have lower percentages.
The Fish and Wildlife Service has an article about how they moved a small population of endangered Columbian white-tailed deer from Julia Butler Hansen Refuge for the Columbian White-Tailed Deer to Ridgefield National Wildlife Refuge (both sites in Washington).
They needed a helicopter to get some of the deer out.
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.
“Mount St. Helens seized the world’s attention in 1980 when the largest historical landslide on Earth and a powerful explosive eruption reshaped the volcano, created its distinctive crater, and dramatically modified the surrounding landscape.” Quoted from the USGS Fact Sheet titled…. Mount St. Helens, 1980 to Now—What’s Going On?
The Washington Department of Natural Resources is reporting on the Whidbey Island landslide. They have links to photo collections, official report, the best “before/after” image pair we have seen, geologic map and more.
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.
