Online_Linkage: https://doi.org/10.14509/31517 Description: Abstract: Thin section analysis of samples from the Haines-Takshanuk Mountains-Chilkat Peninsula area STATEMAP project, Southeast Alaska, collected 2022 and 2023, Raw Data File 2025-6, offers comprehensive petrographic descriptions of rock samples collected from various stations visited during fieldwork for the Haines-Takshanuk Mountains-Chilkat Peninsula area STATEMAP project near Haines, Alaska. The project area encompasses portions of the Skagway A-1, A-2, B-1, B-2, and B-3 15-minute quadrangles, covering approximately 300 square miles. The data tables provide observations on lithologic classification, texture, mineral crystal structure and development sequence, and mineral components. This work primarily aims to differentiate between igneous rocks, volcaniclastic metasedimentary rocks, and volcaniclastic metavolcanic rocks. These data and report are available from the DGGS website: http://doi.org/10.14509/31517. Images are archived in the Geologic Photos of Alaska database (Athey and others, 2017, https://maps.dggs.alaska.gov/photodb/#search=rdf2025-6). Purpose: On December 2, 2020, a landslide triggered by an atmospheric river weather phenomenon at Beach Road in Haines, Alaska, claimed two lives. During the same rain event, numerous debris flows were recorded around town, especially along Lutak Spur Road (Nicolazzo and Larsen, 2025). The goal of the Haines-Takshanuk Mountains-Chilkat Peninsula area STATEMAP project was to construct a comprehensive 1:50,000-scale geologic map using modern analytical methods to assist land managers and residents in making informed decisions when planning future development and evaluating risks to infrastructure.

It has undergone limited technical review but does not necessarily conform to DGGS editorial standards. Interpretations contained in this publication are subject to change. Observations in the data tables include lithologic classification, texture, mineral crystal structure and development sequence, and mineral components. Mineral and component modal percentages apply only to the portion of the rock displayed in the thin section. Although the classifications and descriptions have been lightly edited for spelling and consistency, the descriptions are typically freeform text written to note key features and highlight uncertainties that may warrant subsequent investigation. Logical_Consistency_Report: Not applicable Completeness_Report: This data release is complete. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Location data for field stations were collected using GPS-enabled tablets or smartphones running the Esri Field Maps app. Data were merged into an ArcGIS geodatabase. The devices have a reported error of 10-12 m. Latitude and longitude are reported in the WGS84 datum. Lineage: Process_Step: Process_Description: Sample descriptions - We cut thin section billets for 55 rock samples for thin section analysis at the DGGS office. The cut samples were sent to Vancouver Petrographics Ltd. for final cutting, impregnation, and mounting. Vancouver Petrographics Ltd. retained 45 thin sections for further staining, photography, and analysis. The remaining thin sections were returned to DGGS in Fairbanks, photographed and analyzed in-house.
