This report presents the findings of a geologic and geotechnical evaluation of a landslide at the Yukon River bridge (the E.L. Patton Bridge). The Yukon River bridge landslide occurred in fall 2012 between approximately 375 and 575 feet west of the bridge. Although there was no damage to the bridge foundation, the landslide's close proximity to the bridge and concerns over additional failures prompted multiple evaluations, including landslide documentation, drainage assessments, and geotechnical studies. This report was prepared to convey the general characteristics of the rock mass, characteristics of rock discontinuities, and the geomorphic expression of the 2012 landslide in the vicinity of the bridge. We determined...
This Raw Data File provides lithologic descriptions of core fragments recovered from a series of core holes drilled by Exxon (mid-80s) in the uplands bordering the Yukon Flats basin. In addition to descriptions of the material, the tabulated file includes geographic location, core hole numbers, an age estimate, core fragment depth, general lithology, grain size, and facies interpretation. The author examined these core materials in Fairbanks during winter and spring 2002. This work was done in preparation for an assessment carried out by the U.S. Geological Survey of undiscovered, technically recoverable hydrocarbon resources in the Yukon Flats basin.
