There isn't a great deal else to describe about this trip. The scenery was as beautiful as it always is. We're in danger of being blase about this, but it's hard to describe in a way that might be interesting to others. Sometimes we pass green boggy plains of muskeg and bright green vegetation, other times it's timeless forests of spruce and hemlock towering over us. Almost invariably snow capped mountains and occasional glaciers loom in the background. 

One thing that was unusual about the scenery on this trip was the trans-Alaska oil pipeline. It's about 850 miles long, and about half is buried. The other half passes through areas where the permafrost starts a few feet below ground and descends in some cases hundreds of feet further. You can't risk burying the pipeline here, because once the heat of the oil melts the permafrost everything gets very unstable. So the thing rides on stilts and suspension bridges for hundreds of miles alongside the highway. All very impressive.

Another effect of the permafrost is occasional road subsidence, where once again a little melting causes undulations in the road. These are often labelled by cunning road signs that say "BUMP". In some cases where things have deteriorated a lot, the sign might say "BUMPS" instead.

Other events on this trip: spied a herd of bison and took in (yet) another glacier. I've given up raving about the beauty of these, so suffice to say there's another picture here and that the Worthington Glacier is the first one that I actually got to chip a piece off with Leatherman.
