High Resolution LiDAR Point Cloud of Bridge and Roadway Infrastructure in Arctic Winter Conditions along the Dalton Highway (81 km road from Finger Mountain), Alaska, 2024

Remote sensing makes it possible to gather data rapidly, accurately, and non-destructively, allowing for access to remote areas in near real-time. LiDAR sensor data were collected along Alaska's Dalton Highway as part of continued efforts to provide more geospatial data in Arctic regions relevant to cold region research. The Dalton Highway, also referred to as Alaska Route 11, is a remote and vital transportation corridor extending approximately 414 miles from Livengood to Deadhorse near the Arctic Ocean. The highway plays a critical role in facilitating access to the Prudhoe Bay Oil Fields and is a key logistical route for energy development in the region. Finger Mountain, located along the Dalton Highway in central Alaska, is a distinctive geological formation characterized by a prominent rock outcrop that resembles an uplifted finger. The region is notable for its permafrost, unique alpine vegetation, and wildlife, making it of interest to geologists and ecologists. The survey was conducted in August 2024; the corresponding point cloud data shows evidence of road degradation as well as other features of the environment.
