Alone, either of the Maroon Bells would be gorgeous — a towering pyramid surrounded by much more randomly shaped mountains. But it wouldn’t be the same if there were only one. They need each other. They are famous because they are a couple. Twins. Bells, not Bell. Never mind the challenges they present to would-be conquerors, in the climbing/skiing sense. The Maroon Bells are a symbol of Colorado’s freedom, possibility, and beauty. Perhaps the symbol. Here is what they looked like last Friday, from the north ridge of Highland Bowl — an Aspen landmark in its own right.
