Tongass National Forest Karst Vulnerability Public View

This data contains the most up-to-date and comprehensive information on the known karst and karst vulnerability within the Tongass National Forest. The data was last updated December 2025 by the Tongass Geology Office in Thorne Bay. Development plans for the Tongass that include surface disturbances, such as timber harvest, road construction, or quarry development, should reference this layer. Plans that would impact areas of high karst vulnerability should be avoided. Data marked with "Lidar Analysis" in the "verification" field are highly likely to be vulnerable areas, though not guaranteed. They have been identified through manual geospatial analysis, not field assessment. Coordinate with the Thorne Bay Geology Office early in the development planning process if your proposal intersects these areas. Not all forest areas have been fully assessed for karst vulnerability. Unassigned areas indicate a lack of assessment, not low vulnerability. As more data becomes available, the vulnerability layer will be updated. Our analysis relies on a geospatial database of karst features (survey points, sinking streams, caves). Surface features were buffered 100 feet from their edge, and caves were buffered based on surveyed passage depth. Sinking streams and their tributaries were buffered 100 feet upstream for at least 0.25 miles. All buffers adhere to the 2016 TNF Forest Plan and amendments. Vulnerability polygons were derived from two sources: field surveys and lidar analysis. * Field Surveyed Polygons: These were collected using modern GPS technology and have known origins. They are attributed as "Field Checked" or "Field Checked Older Data" based on data quality and provenance. * Lidar Analysis Polygons: These were created using high-resolution DEMs and manual assessment by geologists. They were assigned vulnerability based on factors such as feature size, depth, slope, proximity to known karst, and water flow patterns. In LUD2 and Geological Special Interest areas, vulnerability assessments were conducted by buffering all internal drainage areas. The decision to use this method took into account field observations, geospatial data and land use goals.
AKFlow Stream Gages

These datasets have been developed through a cooperative effort between Interagency Hydrology Committee for Alaska (IHCA) members. The University of Alaska Anchorage's (UAA) Alaska Center for Conservation Science (ACCS) geographer compiled data supplied by individual agency staff from the Alaska Department of Fish and Game (ADF&G), Alaska Department of Natural Resources (ADNR), the National Weather Service's (NWS) Alaska-Pacific River Forecast Center (APRFC), the US Bureau of Land Management (BLM), University of Alaska Fairbanks (UAF), the US Fish and Wildlife Service (USFWS), and the US Geological Survey. AKFlow project staff at ACCS have assembled basic metadata pertaining to each gage's location, status (active or inactive), dates of operation, contact information, and links to available online data where available. The AKFlow inventory also includes 775 polygons representing the upstream drainages for 837 gage records. These drainages were sourced directly from the USGS (https://www.sciencebase.gov/catalog/item/66440867d34e1955f5a427fa) and here https://www.sciencebase.gov/catalog/item/66440948d34e1955f5a427ff or they were derived using current HUC12 drainages from the latest Watershed Boundary Dataset (WBD) and a combination of satellite imagery and a 5 meter digital elevation model (Alaska IfSAR).
OTC Timber Sales Public View

This layer stores all timber sale records for the Alaska Division of Forestry Over The Counter timber sales. This view was created for the public to view and bid on Over-The-Counter (OTC) timber sales for immediate purchase. This list is updated periodically as sales are sold. All sales that have a status of 'OTC' are in this view layer. This view is derived from the Silviculture hosted feature layer, where all features with a status of 'OTC' are included in this view. This layer contains all OTC sales throughout the state. Over the Counter Timber Sales are sales that have been offered at auction and were not purchased. More information about Over The Counter sales can be found [here].
Timber Sales Statewide Public View

This public view displays the statewide Alaska Division of Forestry timber sales. This view is derived from the Silviculture hosted feature layer, where all features with a status of 'Active' or 'Terminated' are included in this view. Though this dataset contains historical timber sale data, there are timber sales sold by DOF that predate GIS records and are largely not included in this layer. This layer can be used to track the sale and termination dates of harvest units, as well as the products sold within the unit. DOF Area offices responsible for the sale, and the land owners, are also included with each harvest unit feature. To find proposed or developing sales, the Five Year Schedule of Timber Sales view should be referenced, as those units will not be included in this dataset.
Scheduled Timber Sales Public view

This layer is the compilations of Timber Sales Layers from across Alaska. Previous layers compiled to create this single layer included the Timber Sales layer (which represented all active and terminated sales statewide), the Five Year Schedule of Timber Sales layer, the Over-The-Counter timber sales layer, as well as each region's locally stored timber sale GIS data records. Those layers have since been deprecated and unshared. Views from this layer have replaced those individual layers, and are editing restricted public facing. Editing views for each area office have also been created, in which the foresters from the respective offices should do create, edit, and store GIS data for the timber sales within their regions. This layer was created primarily by collaboration between the Fairbanks GIS office and the Fairbanks Area foresters. Further adaptions and attributes have been added to incorporate region specific data for different offices. Those attributes have been queried within views for the offices which use them. Please contact DOF GIS with any questions. This public view is created from the Silviculture data using a query of In Current or Preceeding FYSTS is Yes
Alaska Coal Resources

This data contains the location of coal resources within the State of Alaska and created in cooperation with the Alaska Coal Association. Total hypothetical coal resources in Alaska exceed 5.5 trillion short tons, equal to about half the estimated coal resources of the United States. Major coal deposits occur in the Northern Alaska, Nenana, and Cook Inlet-Susitna provinces.

Facilities - 2022 Statewide Comprehensive Outdoor Recreation Plan

Data Last Updated: April 2026 Purpose: The purpose of these data was to provide an inventory of Facilities and Activities for analysis of the supply of recreational facility related recreational resources to develop the 2022 Statewide Comprehensive Outdoor Recreation Plan. These data are of various qualities and level of completeness. Organizations that maintain park facilities data were contacted between February and November of 2022 to gather these data from open data sites or internal data sources. Methodology: Each Facility was gathered, inventoried, reviewed then processed using a geoprocessing model which ran through the following steps: 1) Data was transformed into Alaska Albers Projection. 2) Data was queried to remove Facilities that were outside of the State of Alaska. 3) Attribute fields were standardize to the SCORP data model. The source facilities layers had 273 unique facility types. These records were simplified to match the symbols supported by National Park Service Official Style. This consolidated all the facility types into 102 facility and activity types represented by the NPS model. Using this model automates the development of the legend symbols. Although the NPS model is very robust some facility types from the original data were not found in the NPS model. [National Park Service Official Style] 5) Data was appended to the SCORP Facilities layer for mapping and analysis. Notes: There was an attempt to buffer these locations in order to analysis the points against mobility data but it was found that these data were unsuitable to do bulk analysis because for the small size of the locations, Overlap in the buffers, Poor spatial accuracy resulting in erroneous results. These data are instead being used to help interpret use in the heat maps by representing the facility at a particulate location in a park.
Trails - 2022 Statewide Comprehensive Outdoor Recreation Plan

Data Last Updated: April 2026 Purpose: The purpose of these data was to provide an inventory of trails for analysis of the supply of trail related recreational resources to develop the 2022 Statewide Comprehensive Outdoor Recreation Plan. These data are of various qualities and level of completeness. Organizations that maintain trails data were contacted between February and November of 2022 to gather these data from open data sites or internal data sources. Methodology: Each trail was gathered, inventoried, reviewed then processed using a geoprocessing model which ran through the following steps: 1) Data was transformed into Alaska Albers Projection. 2) Data was queried to remove trails that were outside of the State of Alaska. 3) Each layer was reviewed for duplication across datasets and where possible duplicates were queried out from the organization that was a secondary source. With the limitations of this project not all duplicates were able to be found and removed a more though or review outside of the scope of the SCORP project would be appropriate for improving these data. 4) Attribute fields were standardize to the SCORP data model. A SCORP legend field for trails assigns each trail to one of the following types Water, Winter, Terra or RS 2477. Originally the source data had 33 original trail types. The source organization and URL link was added to the data to get easy access to the original dataset. Regional and organization fields were also added to support developing reports and dashboards. 5) Data was appended to the SCORP trails layer for mapping and analysis. Notes: Selected trail systems were buffered and overlaid with park information then compared to cell phone mobility data to analyze use of individual trails. These trail systems included the Caribou Hills Snowmobile Trails, Petersville Area Snowmobile Trails, Chugach State Park, Denali State Park, and a few other areas.
