This data release is part of a larger project developed in response to the deadly December 2, 2020 landslide in Haines, Alaska. The project area includes portions of the Skagway A-1, A-2, B-1, B-2, and B-3 15-minute quadrangles, an area of approximately 777 square kilometers and produced a 50,000-scale bedrock and surficial geologic map of the Haines Takshanuk Mountains-Chilkat Peninsula area of Southeast Alaska. These data and report are available from the DGGS website: http://doi.org/10.14509/31416. Purpose: During the 2023 summer field season, geologists from the Alaska Division of Geological & Geophysical Surveys (DGGS) conducted fieldwork supporting surficial and bedrock mapping for the Haines-Takshanuk Mountains-Chilkat Peninsula area STATEMAP project. This publication serves as an archive of Schmidt hammer testing and unconfined compressive testing results from selected rock cores and supports research discussion and collaboration.

When applicable, errors are reported in the data tables. These data are being released in the DGGS Raw Data File series. Reports in this series present field data and analytical results with limited or no interpretation by DGGS staff or project collaborators. Analytical results may include interpretations by laboratories when an interpretive review of the analytical findings is necessary to develop usable output. The reports and accompanying data have been evaluated by project staff for general readability and logical consistency but have not undergone technical peer review. Logical_Consistency_Report: Not applicable Completeness_Report: This data release is complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: We recorded location information using GPS-enabled tablets running Esri ArcGIS Field Maps app, with a reported horizontal error of approximately 5 to 10 meters. Latitude and longitude are reported in the WGS84 coordinate system. Lineage: Process_Step: Process_Description: Sample collection - In August of 2023, field teams from the Alaska Division of Geological & Geophysical Surveys (DGGS) and the University of Alaska Fairbanks (UAF) conducted Schmidt hammer testing on 30 rock outcrops at selected field station locations and collected rock samples from four locations for unconfined compressive strength (UCS) testing. We recorded location information using GPS-enabled tablets running Esri's ArcGIS Field Maps app, with a reported horizontal error of approximately 5 to 10 meters. Latitude and longitude are reported in the WGS84 coordinate system. Process_Date: 2023 Process_Step: Process_Description: Schmidt hammer testing - The hammer is pressed perpendicularly against the concrete or rock surface until the spring-loaded piston rebounds. The rebound values displayed on the scale can be correlated to compressive strength using a conversion chart. We used Schmidt hammer types L and N, specifically designed explicitly for rocks and manufactured by Proceq, at each selected outcrop to assess the compressive strength of the rock. We took ten readings at each location using each hammer type. We performed the tests in general accordance with ASTM D5873-14, except that we did not use a grinding stone to smooth in situ rock surfaces. Testing was performed where the rock appeared most intact rather than being conducted on a grid pattern. The accompanying report provides additional detail. Process_Date: 2023 Process_Step: Process_Description: Unconfined compressive strength testing - We collected rock samples representing major rock types in the region for UCS testing. We collected at least five samples of each rock type that could potentially yield cores longer than 10.2 cm (4.0 in); because of weight and space constraints in transporting samples to Fairbanks, we only collected samples from four selected locations. We submitted samples to the Frozen Soil Testing Laboratory at UAF for preparation and testing. Testing was performed in accordance with ASTM D7012-14e1, "Standard Test Methods for Compressive Strength and Elastic Moduli of Intact Rock Core Specimens under Varying States of Stress and Temperatures, Method C" (ASTM International, 2014b). To obtain the 2:1 length-to-diameter ratio required by this method, a 5.08 cm (2 in) diameter coring bit was used to obtain cores that were then trimmed to a length of 10.16 cm (4 in). Depending on the dimensions and competency of the collected rock samples, up to four cores were obtained from each rock and subjected to UCS testing.
