The history of Gresham, Oregon, is rooted in the pioneers who trekked along the Oregon Trail in the 1800s. Traveling down the Columbia River or over the precipitous route by scenic Mount Hood, they arrived in what was then called Powell Valley, so named by the first settlers. They found trees that were unparalleled, tall, and straight, which they used to build their first communities. The rich, fertile land was cleared to grow an array of crops that would eventually make the area well known for its agriculture.
