One of KC's all time favorite tracks, and not just because of the billboard, this one takes you over some of the most amazing jumps you'll find in any track. Using excavation textures and the road constructed out of the most unlikely of them, you'll find yourself constantly on the brink of plunging right off the edge and out of the race. Its most striking feature can be hinted at through its name: altitude. The altitude work is probably one of the best. No blind jumps, no blind curves; you see everything before it happens and you sometimes wonder whether you'll make it across, only to find that you somehow, amazingly, have. This track works at all levels and is a hoot in multiplayer.

Oh, but the steve miller race music only lasts for one play; sorry, no looping.
