As a lpollock pointed out to me from his experience of climbing to the North Peak of Cascade via the Upper Pole Coulior "it almost felt like cheating". It only took 2 hours to top the mountain, and about 15 more minutes to summit the north peak. So I wandered over the the north most peak with the weather (or maybe radio?) tower on it too. Upper Pole is a great way to climb this mountain.
I tried this once in the summer, but couldn't even find it. Then tried again last spring, but chickened out part way up. Finally made it to the top yesterday (April 14, 2007). It was perfect conditions. Awesome! Best/easiest way up Cascade...
