A few months ago we featured the work of astrophotographer Matt Dieterich, whose iconic photo of star trails over Mt. Rainier was selected for a special series of U. S. postage stamps commemorating the 100th anniversary of the U.

S. National Park Service. If you haven't seen those photos, you should definitely check them out.

In honor of International Dark Sky Week, Dieterich has just released a time-lapse video called Pacific Northwest Nights, using photos shot while working at Mt. Rainier National Park. Of course, we love it because it highlights places in our own backyard, but even if you've never been to our part of the world it's a beautiful video, and a reminder of why dark skies matter.

If you pay close attention at 0:50 and 2:45 you can even see the glow of headlamps as climbers ascend Mt. Rainier. You can find more of Dieterich's work at his website and on Instagram.
