Here we are in The Dalles, Oregon. It is not ‘Dalles’ or ‘Dallas,’ but rather ‘The Dalles,’ one of the most historic towns in the state. It was called Le Dalle by the early French trappers, which means flat topped rock or flagstone, as seen in the flat-topped basalt islands that surround the Highway 197 bridge. After dinner last night, we transited two dams, the John Day Lock and Dam and The Dalles Lock and Dam just before sunrise. The Dalles Dam has had the greatest impact on the history and culture of the Pacific Northwest. When it was closed on March 10, 1957, many native locations were submerged behind the dam.
