Greetings to WyGeo -
The USGS recently released some more aerial LiDAR point cloud (LPC) tiles for Wyoming and Montana. These tiles are QL1 data, the highest quality typically provided by USGS.
New coverage is of several hydrographic sub-basins of the Yellowstone River within Yellowstone National Park and the Custer Gallatin National Forest, along with a small part of the Shoshone National Forest. Communities covered include Mammoth, Wyoming as well as Gardiner, Silver Gate, and Cooke City, Montana. The coverage area was particularly affected during the rain-on-snow event of June 2022 that caused much flooding and associated damage. The data released this week was collected after that event.
A georeferenced PDF map showing the area of the latest releases is available here.
The yellow area on that map was released on Thursday 02 January 2025. The black line running east-west around the center of the yellow area is the Montana-Wyoming border and the blue line is the Yellowstone National Park boundary.
The new LPC coverage areas do not appear on the image currently provided at The National Map Download when you click on "Show" but that should change in the next few days. On Friday 03 January 2025 the tiles are there ready for free downloading using the various selection methods.
It appears that raster (GeoTIFF) one-meter digital elevation models (DEMs) are not yet available for this new data. Generally USGS delays issuing new DEMs until after all LPCs in a project are completed and released. The USGS refers to this project as "WY GrandTetonNP D22" and this project is called "2022 Grand Teton National Park Lidar" on the US Interagency Elevation Inventory webpage.
