C. Russell Dunn is a retired New York State-licensed hiking guide and the author of many regional outdoors and history-oriented hiking guidebooks, including Adirondack Waterfall Guide: New York’s Cool Cascade; Catskill Region Waterfall Guide; Trails with Tales: History Hikes through the Capital Region, Saratoga, Berkshires, Catskills and Hudson Valley; and Paths to the Past: History Hikes through the Hudson River Valley, Catskills, Berkshires, Taconics, Saratoga and Capital Region, (the latter two cowritten with his wife, Barbara Delaney). He lives in Albany, New York.
""Russell Dunn, who has written many, many books taking us outdoors throughout our region, commonly to see waterfalls, has done it again. He has written a book about rocks, lots of them. He claims it is about 'boulders and unusual rock formations,' but it is far more than that. If it is made of rock and is interesting, then it is fair game for this book Somehow, he has amassed a list of notable boulders, caves, outcrops, etc. in our region and researched them all. He takes you to each one and tells you all about them. None of us will ever get to see them all, but we will all want to try. This is the perfect gift for your rockhound friend or your rockhound self."" — Robert Titus, coauthor of The Hudson Valley in the Ice Age
