First published in 1955, Midwest Gem Fossil and Mineral Trails - Prairie States is an indispensable guide for any rockhound collecting in Iowa, Kansas, Missouri, Nebraska, Missouri, North Dakota, or South Dakota.
For the rock hobbyist, lapidary and fossil enthusiast these states have much to offer. Lake Superior agates are widespread. Magnificent fossils occur in each state. Superb crystals of quartz, calcite, pyrite, marcasite, dolomite, celestite, selenite, spalerite, and barite are not difficult to come by. There are also numerous rare minerals which provide an extra thrill for the field collector.
Helpful hints for collecting minerals, gem materials, and invertebrate fossils are highlighted by an author who has collected in these states for over 50 years.
An essential guide for the beginning and experienced collector alike, Midwest Gem Fossil and Mineral Trails - Prairie States, highlights the best of the region in one handy volume. 128 pgs.
The Mineral Hardness Ruler is a stimulating visual aid, educates in one phase of mineralogy, and provides the standard ruler measurement scales needed in classes.
Rockhounds, mineral enthusiasts, students, teachers, geologists, and any one interested in rocks and minerals will find the Mineral Hardness Ruler a handy visual aid for quick information on mineral hardness.
The two-sided, flexible, glossy, vinyl ruler consists of five scales: three measurement scales and two mineral hardness scales. The measurement scales are in standard ruler measurements of tenths of inches, sixteenths of inches, and millimeters. Mohs' relative hardness numbers are integrated into the inch scales, while a separate scale exists for an absolute mineral hardness scale by Rosiwal.
On one side of the ruler are pictures of the ten common minerals, in full color, selected by Mohs for his relative hardness scale. On the reverse side of the ruler are six common items with their relative hardnesses. These items, along with known minerals, can be used as a handy field kit to test the relative hardness of an unknown mineral.
Hardness is one property of a mineral that can be used to distinguish among similar minerals. A given mineral can scratch any other mineral of the same or softer hardness. Over a hundred years ago, the German mineralogist Frederick Mohs devised the relative hardness scale that has found favor with mineralogists for over a century. Others, such as Rosiwal, formed absolute hardness scales using the same minerals as Mohs. For example, diamond, the hardest substance in Nature is not twice as hard as apatite, 10 versus 5, but over twenty thousand times as hard, 140,000 versus 6.5.

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.
