Detrital zircon geochronology along a structural transect across the Kahiltna assemblage in the western Alaska Range: Implications for emplacement of the Alexander-Wrangellia-Peninsular terrane against North America Detrital zircon geochronology along a structural transect across the Kahiltna assemblage in the western Alaska Range: Implications for emplacement of the Alexander-Wrangellia-Peninsular terrane against North America
The Kahiltna assemblage in the western Alaska Range consists of deformed Upper Jurassic and Cretaceous clastic strata that lie between the Alexander-Wrangellia-Peninsular (AWP) terrane to the south, and the Farewell and other peri-cratonic terranes to the north. Differences in detrital zircon populations and sandstone petrography allow geographic separation of the strata into two...

Bathymetry and geomorphology of Shelikof Strait and the western Gulf of Alaska Bathymetry and geomorphology of Shelikof Strait and the western Gulf of Alaska
We defined the bathymetry of Shelikof Strait and the western Gulf of Alaska (WGOA) from the edges of the land masses down to about 7000 m deep in the Aleutian Trench. This map was produced by combining soundings from historical National Ocean Service (NOS) smooth sheets (2.7 million soundings); shallow multibeam and LIDAR (light detection and ranging) data sets from the NOS and others...

Tsunamigenic splay faults imply a long-term asperity in southern Prince William Sound, Alaska Tsunamigenic splay faults imply a long-term asperity in southern Prince William Sound, Alaska
Coseismic slip partitioning and uplift over multiple earthquake cycles is critical to understanding upper‐plate fault development. Bathymetric and seismic reflection data from the 1964 Mw9.2 Great Alaska earthquake rupture area reveal sea floor scarps along the tsunamigenic Patton Bay/Cape Cleare/Middleton Island fault system. The faults splay from a megathrust where duplexing and...

Dropstones in lacustrine sediments as a record of snow avalanches - A validation of the proxy by combining satellite imagery and varve chronology at Kenai Lake (south-central Alaska) Dropstones in lacustrine sediments as a record of snow avalanches - A validation of the proxy by combining satellite imagery and varve chronology at Kenai Lake (south-central Alaska)
Snow avalanches cause many fatalities every year and damage local economies worldwide. The present-day climate change affects the snowpack and, thus, the properties and frequency of snow avalanches. Reconstructing snow avalanche records can help us understand past variations in avalanche frequency and their relationship to climate change. Previous avalanche records have primarily been

Pace and process of active folding and fluvial incision across the Kantishna Hills anticline, central Alaska Pace and process of active folding and fluvial incision across the Kantishna Hills anticline, central Alaska
Rates of northern Alaska Range thrust system deformation are poorly constrained. Shortening at the system's west end is focused on the Kantishna Hills anticline. Where the McKinley River cuts across the anticline, the landscape records both Late Pleistocene deformation and climatic change. New optically stimulated luminescence and cosmogenic 10Be depth profile dates of three McKinley...

New approach to assessing age uncertainties – The 2300-year varve chronology from Eklutna Lake, Alaska (USA) New approach to assessing age uncertainties – The 2300-year varve chronology from Eklutna Lake, Alaska (USA)
Developing robust chronological frameworks of lacustrine sediment is central to reconstructing past environmental changes. We present varve chronologies from five sites extending back 2300 years from Eklutna Lake, in the Chugach Mountains of south-central Alaska. The chronologies are built from image analysis of high-resolution photographs and CT scans of sediment cores. The age...
