The famous Estwing Geo/Paleo Pick GP100 has made a grand reentry after being out of production for several years. The handle has been beefed up to make the unit even stronger. It is 25 inches long with a total weight of 3 pounds. Painted steel with a soft vinyl grip. The light weight but great strength of this makes it a great field tool for any geologist or rockhound.
Not only is this a great digging tool but I use mine to help me navigate the steep slopes of mine tailings. Jab the tip in and pull yourself up then use the hoe end to cut a quick shelf to work from.
A fascinating treasure hunt awaits you in the Centennial State. Rockhounding Colorado takes you to nearly one hundred of the best rockhounding sites in the state. Search for amethyst and quartz at the Crystal Hill Mine. Check out the view at Douglas Pass while looking for leaf imprints and insect fossils. Or head to Saint Peters Dome to uncover green, white, and purple fluorite.
Veteran rockhounders William and Cora Kappele lend their more than thirty years of experience, outlining some of the best places to turn up rhodonite, agate, pyrite, and more. You?ll get the inside dirt on the best seasons to hunt, what you?ll find at each site, where to spend the night, and even special attractions to visit while you?re in the area.
Look inside for: detailed descriptions of each site; information on what tools to bring; advice on what kind of vehicle is needed to get to each site; lists of BLM, county office, and National Forest contact information.
Whether you?re a beginner or veteran collector, let Rockhounding Colorado be your guide on your next rockhounding adventure.
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.
