Wasco County, in Oregon was established in 1854 and was named for the Wasco (or Wascopam) Indian tribe.
The Dalles is the County seat. Now the trading hub of north-central Oregon, The Dalles gained earlier fame as the town at the end of the Oregon Trail. Thousands of years before that, Native Americans painted pictographs and etched petroglyphs on rocks overlooking the Columbia River in this area.
