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).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.>data: Table of identification numbers, coordinates, photomicrograph descriptions, and an accompanying data dictionary.20242025ground conditionCompleteNone planned-135.743526-135.05764859.40917258.841734ISO 19115 Topic CategorygeoscientificInformationAlaska Division of Geological & Geophysical SurveysActinoliteAmphiboliteAnalysesAnalyses and SamplingAnalytical Lab ResultsAnalytical ResultsAndesiteApatiteArkoseBedrockBedrock GeologyCalciteCementChertChloriteClayConglomerateCrystalsDiopsideDioriteEpidoteFeldsparGabbroGeologyGlassGranodioriteHematiteHornblendeIgneousIgneous RocksIntrusiveIronKaoliniteMagnetiteMetamorphic RocksMonzodioriteMonzograniteMonzoniteMuscovitePetrographicPetrographyPetrologyPlagioclasePotassiumPumicePyritePyroxenitePyrrhotiteQuartzQuartziteSample LocationSandSandstoneSedimentarySedimentary RocksSericiteSiltSiltstoneSmectiteSyeniteThin SectionTonaliteTrachyteTremoliteTuffVolcanicZirconAlaska Division of Geological & Geophysical SurveysBattery PointBattery Point TrailChilkat PeninsulaChilkat State ParkComet MinesFalse Battery PointFerebee RiverFerebee ValleyHainesHalutu RidgeJohnson CreekJualin MineKasidaya CreekKelgaya PointKochu IslandLehunua IslandLehunua PointLetnikof CoveLily LakeLow PointMink CreekMount VillardParadise CoveSoutheast AlaskaTananiTanani PointTanani VillageTlegu BeachTukgahgo MountainThis report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).Any hard copies or published datasets utilizing these datasets shall clearly indicate their source.

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.Not applicableThis data release is complete.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.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.2024point0.00000010.0000001decimal degreesWGS84WGS 846378137298.257223563rdf2025_006_haines-petrography_data.csv, rdf2025_006_haines-petrography_data_dictionary.csvTable of identification numbers, coordinates, photomicrograph descriptions, and an accompanying data dictionary.DGGSdataAlaska Division of Geological & Geophysical SurveysMetadata Managermailing and physical
