    • The Cascades really are an awesome and interesting range. The way the mountains are punctuated with these solitary peaks is so memorable. One of my favorite spots is up on Smith Rock, where you can see them lined up, punctuating the horizon all the way up to Washington! You are right too, in recognizing how each has its unique personality.

  4. This is a very intriguing synopsis of these Cascade giants. I horde maps and study their topographic terrain and elevations. When we lived in Oregon, I studied and memorized all of the Cascade highpoint elevations, ridges, trail systems, summit approaches and mountain climbing accidents from Lassen to Garibaldi. I summited some of them and even almost fell in Mt. St. Helens in July of 2004 just weeks before she blew again and the trail was closed until 2007. I even made my wife summit South Sister where I proposed to her on what was the last good day up there in late September 2011 before the winter blanket. I still have all of the maps and occasionally study them but now in the very rugged and high mountain state of Idaho, I’m now studying the endless ranges out here. Just a question, what were your findings on Lassen Peak, Mt. Jefferson, Glacier Peak and Mt. Baker? And would the Three Sisters be considered one mountain or are they three individual mountains? I also remember years back that geologists found that a fourth Sister Mountain is growing. As stated in the above comment, I am kind of a nerd when it comes to these statistics (in addition to knife steels and guns). I’ve been in contact with multiple topographic map companies like Adventure Hiking Maps (Oregon) and Beartooth Publishing (Montana) about this stuff and making even more maps! Especially here in Idaho. Great article and keep us updated.

    • I forgot to add Newberry Caldera. Did you add that in your findings? I have to add, interestingly Humphrey’s Peak in Arizona is another massive mountain that blew like Mt. St. Helens in 1980. At one point it was one massive volcanic cone that rose to between 16,000 and 20,000 feet! I always wondered how big some of the Cascade peaks were. Supposedly Mt. Rainier could have topped out at 16,000 feet as evidenced from the three cones on top. Mt. Adams obviously was higher as well, seeing that massive slide from the Takhlakh Lake side of the mountain. In addition, Mt. Hood supposedly had an elevation above 12,000 feet and Mt. Jefferson must have been higher as well. Mt Mazama’s elevation is the real unknown. But I was always curious at what elevations the eroded peaks like the ‘Lightning Rod’ Mt. Thielsen, Mt. Washington, Three Fingered Jack and Newberry Caldera before the glaciers carved out what’s left of their interiors.
