These are two of the “Three Sisters”, a range of mountains located west of Bend, Oregon. You are seeing North Sister and Middle Sister. South Sister is a little shy and is hiding behind Middle Sister from this vantage point. The locals have nicknamed the three mountain peaks Faith, Hope and Charity.
This photo was taken from the parking lot of the Dee Wright Observatory, located along the McKenzie Pass Scenic Highway. To get here I traveled through the little town of Sisters (go figure), a real cute little town which hosts lots of music festivals and a huge annual quilting event.
