I use https://coast.noaa.gov/inventory/ quite a lot to see what elevation products (usually looking for lidar) are available for any given area.
So LIDAR was flown in 2016 in the Bethel area. https://coast.noaa.gov/dataviewer/#/lidar/search/where:ID=6264 There's an option to bulk download the raw laz files. I'm curious what your process is for incorporating the lidar into osm.
