      Strain accumulation in the Yakataga seismic gap has been estimated from the deformation of a 60 km × 40 km trilateration network surveyed in –, , and The contraction in the approximate direction (N19°W) of plate convergence is ± μstrain/yr, and there is a minor ( ± μstrain/yr) orthogonal by: YAKATAQA AREA PLAN POINT RIOU TO YAKUTAT BAY - TIDELANDS, SUBMERQED LANDS, AND SHORELANDS Background Unit 6 is characterized by its remoteness and glacially-influenced topography. Physical features Yakutat Bay and Russell Fiord were formed by the scouring forces of glacier advance and subsequent retreat.

      Alaska geology, though, doesn’t only consist of the catastrophic. Besides a vast array of massive glaciers, Alaska features geologic oddities like Katmai National Park’s Valley of Ten Thousand Smokes, where ash from a volcanic eruption remains in some places more than feet thick! Geologic Map of Baranof Island, southeastern Alaska. This map updates the geology of Baranof Island based on fieldwork, petrographic analyses, paleontologic ages, and isotopic ages. These new data provide constraints on depositional and metamorphic ages of lithostratigraphic rock units and the timing of structures that separate them.

Geology of the Yakataga district, Gulf of Alaska Tertiary province, Alaska: Series title: Open-File Report: Series number: DOI: /ofr Edition-Year Published: CHAPTER 1. INTRODUCTION. The Yakataga Area Plan directs how the Alaska Department of Natural Resources (DNR) will manage state uplands, shorelands, tidelands, and submerged lands between Cape Suckling and the northern boundary of Glacier Bay National Park (near Dry Bay).

A summary chapter provides an overview and presents a possible model for Alaska's Phanerozoic evolution. The Geology of Alaska is the largest publication produced in the Decade of North American Geology program, a fitting tribute to this magnificent area.

Glacial marine sedimentation began during the late Miocene and is recorded in lowermost Yakataga strata exposed at Yakataga Reef by the abrupt arrival in a deep basin of turbidites and chaotically bedded debris flows.

Debris flows, as much as 19 m thick are composed largely of glacial debris brought down to sea level by tidewater glaciers.

A gravel road leads one mile from the Yakataga airstrip to the Duktoth River and bridge. The road and bridge do not receive regular maintenance and may pose a safety hazard and liability. Beyond the bridge, an abandoned roadbed heads west across the lowlands from Duktoth River to Kaliakh River.

George Plafker (written commun., ) reports that the Yakataga Formation is at least 4, m thick in the Mount Saint Elias and Mount Fairweather quadrangle. Interbedded gray to dark-gray and greenish-gray siltstone, mudstone, and sandstone predominate in lower third of formation.
