Bruce Leis has been an enthusiastic collector and researcher of stromatolites for over two decades. He has visited them worldwide, photographing their distinctive patterns and studying their geologic setting. In 2015 he teamed up with retired professor Bruce Stinchcomb and paleo-artist Terry McKee to produce a unique book detailing these wonderful and important geologic features. Anyone interested in earth’s geologic history and the development of life on this planet should enjoy their wonderfully illustrated 176 full page size treatise.
A music review ? Well, if you are a rockhound (and you probably are if you stumbled to my blog), and you like music (who doesn’t) then this might be just for you. With song titles like “The Crystals that I’ve Known”, “Agate Lickers”, “Gold is Where you Find it”, “The Mineral Dealer”, and Damn the Glaciers” how could you possibly not be interested in a music CD entitled “Nuggets and High Grade”?
What do you call chemical compounds that are comprised of isolated silica tetrahedron: that is, where the tetrahedrons do not share any corner oxygens with other tetrahedron, but rather are connected by cations in various configurations? Why, orthosilicates, of course. Olivine, garnets, zircon, staurolite, and topaz are orthosilicates, to name a few. So is titanite, one of our favorite Bancroft, Ontario minerals.
When Dr. Robert Lauf arrived at the Rochester Mineralogy Symposium in April he was carting several boxes of his newly minted book entitled “Collector’s Guide to the Silicates: Orthosilicates”. After his Friday morning talk on the topic, the line to obtain signed copies was predictably long. I got there early to secure mine, but I do believe Robert was prepared and everyone who desired a signed copy at the symposium was rewarded. Continue reading
Another wonderful book on a classic New York State mineral location is available. Many of us have ventured to the Bower Powers Farm in Pierrepont to collect black tourmaline. We have driven Post Road to the washed out bridge over Leonard Brook, hiked along the brook to the tourmaline laden pits, and collected what we could carry. But did you ever want to know more about the rich history of the location, the multiple collecting sites, the varied geology, or the complete mineralogy of this classic site?
BOOK REVIEW: New York Rocks and Minerals: A Field Guide to the Empire State, by Dan and Bob Lynch (2016)
There is a new publication available entitled “New York Rocks and Minerals: A Guide to the Empire State”. It is authored by Dan and Bob Lynch and published by Adventure Publications of Cambridge, MN. The 2016 book is available online for less than $20 on Amazon.
For each of 105 rocks, minerals, and fossils found in New York State this book provides a page of pictures designed to illustrate the specimen’s most characteristic identifying traits and an opposing page providing information on environment, what to look for to identify it, size, color, occurrence, and a notes section with other pertinent information. The format and presentation is very easy to use. In addition, beginners should enjoy the several page overview of New York geology. The 14 page “Quick Identification Guide” based on color and then expanding into other properties may be just the ticket for some.
Thanks to Mike Walter, a teacher and mineral dealer by trade, but a true collector by heart, we can learn more about the little (and sometimes not so little) doubly terminated clear quartz crystals than most thought probably could be known.

The cold has arrived and the snow has covered our favorite collecting sites, but that does not mean that we cannot read about them. There are even novels written about some of the fossil-rich sites in western New York. In this case, a children’s novel, set in the prized fossil location, Kashong Glen.
Cynthia DeFelice, a nationally known writer of children’s books, attended William Smith College in Geneva and never left the area. She was a school librarian in our club’s home town of Newark in the 1980’s and now claims she does most of her writing from a second floor room in her home in Geneva overlooking Seneca Lake. She has authored over 30 children’s books including a series of ghost stories featuring Allie Nichols, who is a 6th grader when she encounters a ghost in Kashong Glen near her home.
Field Guide to the Devonian Fossils of New York by Karl A. Wilson (Paleontological Research Institute, 2014): This compact (6” by 9”) spiral bound fieldbook is a update to the1994 PRI publication by David Linsley. After introductory sections on general Devonian stratigraphy and geology and a section of fossil collecting methods, the book systematically introduces Devonian fossils. Sections on sponges, corals, bryozoa, brachiopods, mollusks, anthropods, trilobites, echinoderms, and more follow with diagrammatic plates offset by descriptive pages detailing the fossils. By limiting the species to those found in New York, you are much more likely to identify your finds with this book than with a more inclusive book. The PRI price is $18 and the book can be obtained online with a modest additional shipping charge. Mine arrived in 3 days !
Some of us have been discussing a long trip to the Lake Superior region next summer, Thunder Bay amethyst, Keweenaw Peninsula copper and more, Petoskey stones, and, of course all those Lake Superior agates. If you like agates, or want to see what we might be able to collect there, I can recommend the following book by Dan and Bob Lynch and published by Adventure Publications in 2011. It lists for $19.95 online, but I found mine at Barnes and Noble.
The compositional variety, the range of color variation, and the diverse origin of tourmalines has led to several books on the subject. Some are very technical, either mineralogically or technically, but for me one stands out for the mineral collector. The Collector’s Guide to the Tourmaline Group by Robert J. Lauf (Schiffer Publishing) combines adequate detail on tourmaline chemistry and taxonomy with a pictorial account of all the recognized tourmaline species. Lauf does all this at a level that is not daunting for the non-geologist. The price is right also, $19.99 list for the oversize softcover book, and I found it for a few dollars less online.
Incidentally, this is one of a series of books published by Schiffer on various minerals or mineral groups. All are informative and affordable and well illustrated.
Rockhounding New York: A Field Guide to the State’s Best Rockhounding Sites by Robert Beard Falcon Guides (2014)
With this informative guide, you can explore the mineral-rich state of New York, from the beaches to the mountains. The book describes the states’ best rockhounding sites and covers popular and commercial sites as well as numerous little-known areas. Although the technical and mineralogical data on the 98 sites is a bit brief, this handy guide does include maps and directions to each site and enough rockhounding information to at least prepare you for your visit.
Brief sections in the front of the book review the state’s bedrock geology and natural resources and there is also a short section on basic rockhounding.
