what's the history behind the name "cape disappointment state park" in WA state?

Answer 1

History
In 1788, while in search of the Columbia River, English Captain John Meares missed the passage over the river bar and named the nearby headland Cape Disappointment for his failure in finding the river. In 1792, American Captain Robert Gray successfully crossed the river bar and named the river "Columbia" after his ship, the Columbia Rediviva. Only a few years later, in 1805, the Lewis and Clark Expedition arrived at Cape Disappointment.
