Description :
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 existence of either permafrost or seasonally frozen ground. The deformations reflect thermokarst activity that occurred when permafrost degraded. Optically-stimulated luminescence permits construction of a tentative Late-Pleistocene permafrost chronology for southern New Jersey.
