The Valley 20 oz Pointed Tip Rock Hammer is similar in weight, and quality, to the Estwing 22oz Pointed Tip Rock Hammer. It is a smaller rock pick than all the Estwing rock picks except the Estwing 14 oz Pointed Tip Rock Hammer. It has a square faced striking surface, larger than the Estwing rock picks, on one end and a pointed pick tip on the other. Made in China but it's high quality. We've sold over 2100 and have only had one returned for a broken tip. (The hammer had what looked like vice marks on it so I suspect the damage was artificially introduced.). This Valley 20 oz Pointed Tip Rock Hammer is a great tool for the professional, student, or recreational geologist and a great rock hammer for rockhounds. It will last you a life time.

This book is both a wonderful source of information for rock hounds and the perfect backpacking companion for tourists and outdoor enthusiasts. Lavishly illustrated with color and black-and-white photographs, as well as extensive graphs and maps, Minnesota's Geology will inform and delight for years to come.

This is a great little pocket guide to rocks and minerals. It uses color drawings to illustrate the rocks and minerals which I find is far more handy that pictures of museum quality specimens. Rocks and minerals in the field often don't know what they're supposed to look like so they are more average than those museum exhibits!
In this book two renowned experts share their lifelong passion for geodes and their extensive knowledge of world-class geode deposits as they present the latest theories on the formation and occurrence of these amazing mineral gifts of nature.
The most comprehensive book ever written on geodes of the Americas - a definitive reference for serious collectors and a delightful mineral exploration for both experts and novices.
