Surficial geologic map of parts of the Misheguk Mountain and Baird Mountains quadrangles, Noatak National Preserve, Alaska Surficial geologic map of parts of the Misheguk Mountain and Baird Mountains quadrangles, Noatak National Preserve, Alaska
The map area, which comprises part of the Noatak National Preserve, includes approximately the southern two-thirds of the Misheguk Mountain quadrangle and the northern one-third of the Baird Mountains quadrangle. It is centered on a belt of west-trending lowlands along the Noatak River which separates the De Long Mountains to the north from the Baird Mountains to the south (Burch, 1990...

Geophysical identification and geological Implications of the southern Alaska magnetic trough Geophysical identification and geological Implications of the southern Alaska magnetic trough
The southern Alaska magnetic trough (SAMT) is one of the fundamental, crustal-scale, magnetic features of Alaska. It is readily recognized on 10 km upward-continued aeromagnetic maps of the state. The arcuate SAMT ranges from 30 to 100 km wide and extends in two separate segments along the southern Alaska margin for about 1200 km onshore (from near the Alaska/Canada border at about 60...

Inventory of marine and estuarine fishes in southeast and central Alaska National Parks Inventory of marine and estuarine fishes in southeast and central Alaska National Parks
As part of a national inventory program funded by the National Park Service, we conducted an inventory of marine and estuarine fishes in Glacier Bay National Park and Preserve, Wrangell-St. Elias National Park and Preserve, Sitka National Historical Park, and Klondike Gold Rush National Historical Park in 2001 and 2002. In addition, marine fish data from a previous project that focused...
