Tumac Mountain
One of the other REU students was an avid hiker, and got two of us to go hiking with her up Tumac Moutains - in the Cascade mountains. Not the hardest hike, but very nice and beautiful scenery. The only problem was the large number of mosquitoes - more than I've ever seen before. In fact, it's possible to see them in some of my photographs. Still, we did survive to make it back down the mountain.
