Black and white postcard showing the Oregon-Washington Railroad & Navigation Company's mainline along the Columbia River as seen from Crown Point, Oregon, circa 1916. The view is looking west towards Portland. Rooster Rock, a natural basalt obelisk, is visible at lower right, while the Rooster Rock Cannery can be seen at bottom center. Nothing remains of the cannery, but Rooster Rock is now the site of a popular state park. The O-WR&N was a subsidiary of Union Pacific and its identity eventually disappeared into the larger road's around 1950. The route along the Columbia River remains a major freight corridor in today's Union Pacific's system. During the 1960s, an interstate highway (designated I-84 in 1980) was constructed through the Columbia Gorge, built between the railroad and the river at this location.
