This terrain is a large terrain featuring a trenching gorge-like feature that curves around in a semi-circular shape and slight hills. It's exactly 100,000 faces/54097 vertices, but the terrain is originally scaled at about 9000 sq. kilometers (about 3475 sq. miles). This terrain was purposely left a bit plain for easy modification (sculpting terrain), untextured, and is ideal for low-poly games.
UPDATE (Feb. 2, 2013):
Issues with the normal map have been brought to my awareness. I'm in the process of fixing them. I'm also retopologizing the terrain into nice even quads and making the file size smaller. I'll put it up as soon as I'm done.
