The Cohos Trail had its origins in a disaster. In 1969, the great earthen and timber crib dam that held back beautiful 223-acre Nash Bog failed utterly high in what is now the Nash Stream Forest. Several years later, the late Arthur Muise, a much revered NH Fish and Game officer and the man for whom Mt. Muise is named, spun a yarn to me about the dam breach and the great flood that destroyed the Nash Stream valley and swamped the streets and the paper mill in Groveton village. His tale was so compelling, I jumped in my tin-can Datsun as soon as I could and drove up to the old dam site.
