Über die Autorin bzw. den Autor

Dan R. Lynch has a degree in graphic design with emphasis on photography from the University of Minnesota Duluth. But before his love of the arts came a passion for rocks and minerals, developed during his lifetime growing up in his parents’ rock shop in Two Harbors, Minnesota. Combining the two aspects of his life seemed a natural choice and he enjoys researching, writing about, and taking photographs of rocks and minerals. Working with his father, Bob Lynch, a respected veteran of Lake Superior’s agate-collecting community, Dan spearheads their series of rock and mineral field guides—definitive guidebooks that help amateurs “decode” the complexities of geology and mineralogy. He also takes special care to ensure that his photographs compliment the text and always represent each rock or mineral exactly as it appears in person. He currently works as a writer and photographer in Madison, Wisconsin, with his beautiful wife, Julie. Bob Lynch is a lapidary and jeweler living and working in Two Harbors, Minnesota. He has been cutting and polishing rocks and minerals since 1973, when he desired more variation in gemstones for his work with jewelry. When he moved from Douglas, Arizona, to Two Harbors in 1982, his eyes were opened to Lake Superior’s entirely new world of minerals. In 1992, Bob and his wife Nancy, whom he taught the art of jewelry making, acquired Agate City Rock Shop, a family business founded by Nancy’s grandfather, Art Rafn, in 1962. Since the shop’s revitalization, Bob has made a name for himself as a highly acclaimed agate polisher and as an expert resource for curious collectors seeking advice. Now, the two jewelers keep Agate City Rocks and Gifts open year-round and are the leading source for Lake Superior agates, with more on display and for sale than any other shop in the country.

<p><b>Quartz</b> <p><b>Hardness:</b> 7 <b>Streak:</b> White <p><b>Area:</b> Extremely prevalent in all three states <p><b>Environment:</b> Lakeshore, riverbeds, gravel pits, and mine dumps—virtually everywhere <p><b>What to look for:</b> White crystals or masses that often fill in the holes or gaps in other rock, or as white, rounded beach pebbles on the lakeshore <p><b>Size:</b> Quartz is very common and can be found in a wide range of sizes, but most commonly, it is walnut-sized or smaller when found on the beach. <p><b>Color:</b> Quartz is generally white or clear but can be stained or tinted to a different color, including gray, yellow, purple, pink or red. <p><b>Occurrence:</b> Very common <p><b>Notes:</b> Quartz is one of the most common minerals in the world and can be found in almost every geological environment. It plays a very large role in forming many rocks and minerals. In the Lake Superior region, it is easily found as white, rounded beach pebbles, or within vesicles (cavities formed by gas bubbles) with a thin lining of crystal points. You can commonly find it filling cracks in large basalt flows. <p>Quartz is responsible for many of Lake Superior’s collectible stones, such as agate and jasper. In fact, these stones are almost made up entirely of hard, dense quartz. <p><b>Where to Look:</b> Quartz is very common around the lake, and it is particularly easy to find where there is exposed rock, especially near the lakeshore.</p></p></p></p></p></p></p></p></p></p></p>
