Friday fold: Three from Alaska

Posted by Callan Bentley

Earlier this week, I was alerted to an online photo collection from the Alaska Division of Geological and Geophysical Surveys. For those of us who are feeling the lack of field work over the past year, it’s pleasant to browse through them and get a taste of backcountry Alaska. Many of the photos are shot on old slide film, but that kind of adds to the “Alaskaness” of them in my view.

Here are a couple of fold photos from the collection, both by Melanie Werdon, both from 2016 near Tok:

And one from 1977 by Charles G. (Gil) Mull:

Happy Friday to you.
