McKenzie Pass-Santiam Pass Scenic Byway
Three Sisters, OR

The three tallest peaks in Oregon, after Mt. Hood and Mt. Jefferson, are the snowcapped Three Sisters. The North Sister (10,085'), Middle Sister (10,047'), and South Sister (10,358'), are all very popular with climbers (the North and Middle Sisters are especially challenging), and hikers (the popular Pacific Crest National Recreation Trail traverses their western flank).

Here's an interesting fact about the Sisters: they were almost going to be named Faith, Hope and Charity, but the Oregon Geographic Names Board turned down this proposal in 1975.
