Crater Lake, Oregon, with lake-bed terrain.
Created from Space Shuttle Radar Topography mission 30m data for the land, and the Crater Lake 2000 bathymetry survey data for the lake-bed (http://oe.oregonexplorer.info/craterlake/bathymetry.html)
After printing I painted the lake-bed area, and filled it up to the correct water-level with transparent resin. Once the resin was set I painted the surrounding landscape with acrylics and inks.
6 top layers to ensure a smooth and gap-free top surface.
