A chronology of Late‐Pleistocene permafrost events in southern New Jersey, Eastern USA
Abstract Frost fissures, filled with wind‐abraded sand and mineral soil, and numerous small‐scale non‐diastrophic deformations, occur in the near‐surface sediments of the Pine Barrens of southern New Jersey. The fissures are the result of thermal‐contraction cracking and indicate the previous existe...
