About
Eighteenmile Island is a 9.89 acre (4 ha) island on the Oregon side of the Columbia River at river mile 174 in Wasco County, Oregon, United States. The official name derives from its location 18 nautical miles west of Big Eddy and the historic narrows now covered by The Dalles Dam. It is about a half mile (0.8 km) downstream of Mosier, Oregon and four miles (6.4 km) upstream of Hood River. It can be seen from Interstate 84, which runs along the Oregon side of the Columbia River, and from the Historic Columbia River Highway. A small rocky "island" downstream of Eighteenmile Island houses a navigational light. The island is mentioned in the journal of Meriwether Lewis, from the Lewis and Clark Expedition.
