The only field guide to stone walls in the Northeast. "Every stone wall is unique and every stone tells a story," says Robert M. Thorson, the author of the first field guide to historic New England stone walls-- one that helps you identify and appreciate those in your yard, neighborhood, and throughout the Northeast. Exploring Stone Walls is like being in Thorson"s geology classroom, as he presents the many clues that allow you to determine any wall"s history, age, and purpose. Thorson highlights forty-five places to see interesting and noteworthy walls, many of which are in public parks and preserves, from Acadia National Park in Maine to the South Fork of Long Island. Visit the tallest stone wall (Cliff Walk in Newport, Rhode Island), the most famous (Robert Frost"s mending wall in Derry, New Hampshire), and many more. This field guide will broaden your horizons and deepen your appreciation of New England"s rural history.
