Of the tradition of roadside geologic descriptions, Buchanan and McCauley write: "In some ways highways provide convenient access to geology because roads often cut through hills, exposing formations never seen before. . . . For many geologist, road construction is an occasion akin to Christmas or the Fourth of July."
The nine highways, which criss-cross Kansas, were chosen for a variety of reasons. Some, like I-70, I-35, and the Kansas Turnpike, carry heavy traffic; some, like U.S. Highways 69 and 36, are the main highways in various parts of the state; others, like U.S. Highways 160 and 83, cut through some of the state's most interesting geology; and one, U.S. Highway 56, was picked because of its history--the road parallels the historic Santa Fe Trail for much of its route, passing the site of old forts and Indian battles.
This unique guidebook combines geological, historical, and cultural information with more than 100 photographs, drawings, and maps. Presented in a refreshingly nontechnical way, it is sure to appeal to tourist and native Kansas alike.
The Deluxe Moh's Hardness Pick Set now comes in two case types. The wooden case is small enough to carry and the top screws into the base to make a perfect desk stand. The plastic case is longer but the thinner size makes it easier to carry in your field tool set.Hardness is an important and quantifiable physical characteristic of a mineral and in your effort to identify an unknown mineral, the hardness, if known, combined with other properties, can narrow your search to just a handful of possibilities. Simply scratch a smooth surface of your unknown mineral with the picks of various indicated hardness. As an example, if a No. 5 pick scratches the mineral, but a No. 4 pick does not, then your mineral hardness is 4.5. Then compare this against a table of minerals listing hardness values to aid in identifying the unknown mineral.
