SkyWatch Friday: Montana Summer Skies, Endless Blue

The Big Sky above Butte, Montana has been very clear, from crystalline sunset (view from Walkerville, Montana):

To bright blue morning moonset (view of Mt Haggin near Anaconda, Montana; moon on ridge at center right):

On a hike along the Continental Divide between the Clark Fork and Big Hole Rivers, the bluebird sky made a good contrast with a lodgepole pine and juniper spotted of pink weathered rock:

Though summer is nearly over in the high country, you'd never know it from these blazing hot clear days (we hit 90 deg F for the first time this summer). But some morning soon, we'll awake to a heavy frost and perhaps a dusting of snow. Soon.
