Dark Skies

5 Star Route

East of Bend by 30 minutes or so, are some of the darkest skies in all of the US. In the late 1960’s, Oregon University took advantage of this and built Pine Mountain Observatory.

The route takes in the beautiful scrub desert of Millican valley and Kotzman basin along with Ponderosa forests higher up on Pine Mountain.

In 2011, the observatory had three large reflector telescopes, with mirrors of thirty-two inches, twenty-four inches, and fourteen inches in diameter, housed in three domes. Observational work under Director Greg Bothun focuses on low-luminescent galaxies, with remote high-speed digital connections between the observatory and the University of Oregon campus and other astronomical data centers.

This ride is unique in that it can make for a very remarkable experience with a bit of planning. With that start your ride an hour or so before dusk and time your arrival at the peak for dusk. Grab a snack. Do a tour of the observatory, view the stars, kick in your courage … and when ready, hop back on your bike and begin the descent with your lights ablazing! **Click to Read More
