Helicopter and ground reconnaissance surveys were conducted in the Yukon River area in the northwestern Livengood Quadrangle to assess the locations and relative activity of tectonic faults that could pose hazards to the Dalton Highway and proposed future infrastructure developments. Previously identified faults were evaluated, including the Victoria Creek fault (southern, middle, and northern strands), the Kaltag Extension fault, and the Tozitna fault. Several unnamed faults and the Hess Creek and Ray River lineaments were also investigated. The results indicate that none of the faults and lineaments investigated are expressed in Holocene deposits and none exhibit tectonic geomorphic features that indicate Quaternary deformation. High rates of geomorphic processes, low rates of tectonic deformation, and thick vegetative cover may inhibit the recognition of tectonic geomorphology. Future investigations using high-resolution topographic datasets would provide an opportunity to validate the conclusions.

"The Alaska Division of Geological & Geophysical Surveys completed surficial-geologic mapping, lidar data evaluations, and paleoseismic trenching investigations along the Minto Flats seismic zone (Minto fault), the Northern Foothills thrust and associated backthrust faults, and the Stampede–Little Panguingue Creek, Healy Creek, Healy, Park Road, Denali, and Castle Mountain faults. Additionally, aerial reconnaissance and lidar assessment were completed along the Tozitna, Kaltag Extension, and Victoria Creek faults. The purpose of these investigations was to summarize the relative tectonic activity for each structure of concern, evaluate fault rupture parameters, and delineate the locations of possible fault crossings of the proposed pipeline route"-- Summary and conclusions.

Reports on a Alaska Division of Geological & Geophysical Surveys multi-year geologic project which was focused on a corridor along the Alaska Highway between Delta Junction and the Canada border. This project provided information, including active fault hazards, is relevant to a proposed Alaska-Canada natural gas pipeline and other future development in the corridor.
