The summer Milky Way sets over the Milk River on the last weekend of the summer.

This was the view last night, Sunday, September 1, from the Visitor Centre hill overlooking the spectacular Milk River valley and the sandstone formations of Writing-on-Stone Provincial Park, Alberta.

The Milk River winds around the park’s campsite, filled on a beautiful long weekend with campers enjoying the clear skies and temperatures in the 30s by day. At night, conditions were perfect. Warm, dry, no bugs, no wind. The best.

I set up two cameras: one for a day-to-night time lapse and one for a time-lapse panning the scene as the Milky Way moved to the west. These two images are frames from the latter.

Above is a shot from later in the evening when the sky was dark …

… while this image is from earlier in the shoot, when the last of the blue twilight still lit the sky and the camera was aimed a little more to the east.

On the horizon at left in the image above lie the Sweetgrass Hills of Montana, a prominent landmark in southern Alberta. The yellow sky glows are from towns in northern Montana.

Lights from the campground and car headlights illuminate the landscape and the eroded hoodoo formations.

Writing-on-Stone Park preserves ancient rock petroglyphs that record scenes from before and after contact with Europeans. It is a sacred site to First Nations people and is a marvellous place for stargazing.
