While not what it was originally named, Cape Disappointment was so named by British Captain John Meares after he failed to find the mouth of the Columbia River. Now a state park in Washington, Cape Disappointment is a popular location for photographing the dramatically high and picturesque waves produced by king tides. Perhaps the Corps of Discovery witnessed such an autumn sunrise with crashing waves during their mostly soggy stay along the Pacific Coast in Washington and Oregon, at the end of the Lewis and Clark National Historic Trail.
