This Just In
"We could see the top of one hill and think that was the last. But when we gained that, others kept rising before us. To look back, in retreat, seemed utterly out of the question. To look forward was to look directly upwards, as the ascent seemed almost perpendicular." Harriet Hitchcock, 13, 1865, Oregon Trail
The OE is Green!
Our editorial process is completely paperless — authors and editors use a one-of-a-kind online workshop developed by Portland State University. We've published hundreds of authoritative entries on Oregon history and culture without hurting a single Douglas Fir. Donate your green to The OE and keep us — and the trees — growing.
