Carroll was an invigorating teaching colleague, a hiking friend with a head full of Latin names for flowers, a ski patrol protector of the beginning skier, a classical-music-with-lunch host in his Biology lab, a cheerleader for Ideas, a reflective skeptic with reverence for the act of thinking. Unique in his community, he can be remembered everywhere: in the landscaping and track at the high school, in the Columbia Gorge Scenic Area, on the mountain trails he loved, and wherever residents gather for thoughtful disagreement and debate. Lucky are we whose paths he crossed.
