The disappearing Pedersen Glacier in Alaska alvin November 18, 2019 - 7:47am

The image here shows two photos of the Pedersen Glacier in Alaska. The black and white image is from 1917, and the open green field is from 2005. I found those photos in this YouTube video after viewing a short video about how warm it is in the Arctic Circle this year, where glaciers are melting during the winter instead of forming new ice.

For more information, the USGS has this page which shows many more examples of disappearing glaciers in Alaska.

A mile-wide meteor hit Greenland and was hidden by an ice sheet

The most interesting story for me yesterday was that a mile-wide meteor hit Greenland, possibly as recent as 12,000 years ago, and created an impact crater 19.3 miles wide. The impact would have released 47,000 times the amount of energy that was released by the Little Boy nuclear bomb that was dropped on Hiroshima in 1945. The impact crater was hidden by a half-mile thick sheet of ice until recently. (The image shown comes from the article I linked to.)

New Year’s Eve in Anchorage, Alaska

This is a series of Facebook posts from an adventurous day in Alaska, December 31, 2010:

1) Hmm, more bad weather today. Adding “tire chains” to the grocery list, and I’m out the door. Driving to Seward to celebrate the new year!

2) Famous Alaska saying: “There’s old pilots, and there’s bold pilots, but there ain’t no old and bold pilots.” Meaning I’m stopping in Anchorage tonight.

3) So ... I was trying to get to Seward tonight, but got stuck in a steep, icy parking lot in Wasilla for a while. I finally decided to drive-slide the car to the edge of the parking lot where there was a small strip of frozen dirt and grass that went up the side of the hill. I got the tires on the right side of the car on that strip, built up as much speed as I could, and finally got my car up the hill. It took more than an hour to get out of there. After that I tried even harder to find tire chains but could not, so I decided to stop in Anchorage. They started the fireworks at 5pm (because of the whole darkness thing), and various shows went on all night, which was a really cool way to spend the evening.

Slid sideways through an icy intersection

Slid sideways through an icy intersection just in time to see a helicopter lift off from the ground with a sunlit mountain range as its backdrop ... pretty awesome.
