This report presents the findings of a geologic and geotechnical evaluation of a landslide at the Yukon River bridge, conducted by the State of Alaska, Division of Geological & Geophysical Surveys (DGGS) through a reimbursable services agreement with the State of Alaska Department of Transportation & Public Facilities (ADOT&PF). De Anne S. P. Stevens provided a technical review of the report.

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 Yukon River bridge. However, this assessment should be considered preliminary and should not be used to determine areas of potential future slope instabilities. A significant amount of additional exploration and slope stability analysis is required to fully understand the landslide hazard in the area of the bridge, as well as the potential for reactivation and/or expansion of the 2012 landslide into adjacent slopes.

Data sources used in this process:
The attributes listed in this dataset were transcribed from field-data collection sheets. The field-data sheets were also scanned and included as an appendix to the manuscript. The geologic interpretations presented in this report have undergone technical review by a geologist of comparable technical expertise. We incorporated the reviewer's suggestions into the final draft when deemed appropriate.
We assigned a "station number" to each outcrop discussed in this report. Near the center of each outcrop, we recorded a single GPS waypoint to approximate the location of each "station." A station number (and GPS waypoint) was not recorded for the area between the stations 10 and 11. However, we did record observations in this area.
Users should note that this table is a compilation of the information provided in tables 1 and 2 to the manuscript. These tables provide only the outcrop locations and rock mass values. To see all of the outcrop measurements and descriptions, users should refer to the field-data sheets (see Appendix B of the manuscript).
