I thought it might be nice to give some concept of the terrain on other sections of trail besides what's provided in the Nome Council Link. For those who don't have Google Earth I've attached are a couple of screen shots from Google Earth giving a "musher's eye" view of the terrain.
As you can see from the eye altitude, at bottom left in the screenshots, the virtual musher is pretty tall
They aren't kidding about the area being remote and, judging from the terrain, windswept.
