The field guide you hold in your hands began with a frog. Well, kind of-Frog Rock in New Boston, New Hampshire.When outdoors writer Dan Szczesny and his daughter Uma hiked out to the famous landmark boulder that looks remarkably like a frog, his six-year-old asked if there were other rocks in the state that were famous as well. Turns out, there are many! And so began a state-wide adventure to visit, document, and learn about one of the state's most famous features-thousands of rocks and boulders.From one of the largest glacier erratics in North America, to the memorial of the state's only convicted witch, to a rock that marks the most New Hampshire-esque love story on record, Dan and Uma narrowed the list down and created a Patch Quest to encourage families to get out and explore parts of the state they might not normally visit. Now, it's your turn. Use this guide to navigate to some of the strangest, most interesting stories-and rocks-in the Granite State.Get out there and start rocking!
