From our friend and colleague Allen Kriesman is the Ultimate Terrain series of landscape enhancement programs for Flight Simulator. Ultimate Alaska X is the perfect companion to our own Alaskan sceneries, providing a replacement of the default MS coast lines, roads, rivers and mesh and with increased quality landclass. Not as detailed as Tongass Fjords of course, but ideal to enhance the terrain around it ! Read all about it on his website and order it through Flight1.
