Within the last decade, my main scholarly output has been six solo-authored books. All are available through bookstores and online. The first three deal with New England’s historic stone walls. The next two deal with the galaxy of kettle lakes from Maine to Montana, and the most famous one being Walden Pond, in Concord, MA. My last book, a celebration of the bicentennial of Thoreau’s birth, is biography and environmental history.
