Permafrost and ground-water conditions in the Glennallen area, Alaska

This report is an outgrowth of permafrost and geologic field studies now in progress in the southeastern Copper River basin, Alaska and is in response to inquiries for information on permafrost and ground-water conditions. Various private and governmental groups have encountered severe differential settlement of building foundations on permafrost, and consequent maintenance problems. Settlement and expansion of communities in the area also have been retarded by the apparent lack of a ready and large source of potable water. The information below is presented to make available data on permafrost and ground-water conditions for the benefit of those undertaking construction projects in the area.
