Thawing permafrost under the pipeline

There’s a section of the Trans-Alaska Pipeline north of Fairbanks that is threatened by thawing permafrost, and steps are being taken to prevent or mitigate damage. Jack says the work is not visible from the Dalton. We’ll provide photos in the future if they become available, but for now here are some of the thermosyphons that are used to keep the permafrost cold under the pipeline, photos taken by us several years ago at about 26 Mile Dalton.

Refreezing Thawing Permafrost

The Dalton Highway in September

Last fall we took a camping/hunting trip up the Dalton.  We were lucky to get tons of beautiful weather.  Only a little rain.  Summer is almost here!

Minus 57 degrees!

Happy 2020!  Jack has been seeing very cold temperatures up on the Dalton.  It’s been as cold as 40 below around Fairbanks but closer to 60 below up north.  Here are some photos from the recent weeks.  Hope everyone enjoyed the holidays and has a terrific 2020!

Welcome to the Dalton

Jack welcomes you to the Dalton, but kind of in the wrong order.  Instead of just getting on the Dalton, he’s just leaving it.  At the very end you can see the Elliot Highway to the right where it continues on to Manley, and at that point he has left the Dalton and is on the Elliot.  It’s a lot simpler than it sounds.  The Elliot Highway was finished in 1959, goes north from Fairbanks and turns west toward Manley, a town a few miles from the Tanana River.  The Dalton Highway was built in the 1970s to supply and access the Trans-Alaska Pipeline and starts where the Elliot turns west to Manley.  If Jack could, he’d redo this video so it goes the right away, welcoming you to the Dalton at it’s beginning.  But it’s such a beautiful day!

Comin’ down The Shelf

You can barely see the surrounding hills and mountains while Jack drives during a snowfall.  Just a nice calm driving experience with a little music to make it more interesting.
