The Bonneville Landslide sent fifteen square kilometers of debris cascading a thousand meters down into the Columbia River Gorge, damming the river with a wall some 200 feet high and three and a half miles long, and backing up a lake that stretched, by the best reconstructions, a hundred miles or more upriver. The Columbia eventually broke through, leaving four miles of rapids — the Cascades of the Columbia, what Lewis and Clark called the Great Schute — and a submerged forest that still stood, in places, into the era of photography.","For centuries before the geology was measured, the crossing was remembered. Klickitat oral tradition holds that a bridge once spanned the Columbia here — a way across \"without getting their feet wet\" — and the Oregon Encyclopedia's account preserves the tradition's own summary of the event: the river dammed, the waters rising far above, then cutting down through the mass to leave the rapids."]},{"heading":"The documented record","paragraphs":["The science and the story have run in parallel for a hundred years. Earlier dating put the slide around 1100 or in the 1600s — close enough to the great Cascadia earthquake of 1700 to tempt a link — but the newest radiocarbon work on three trees killed by the slide and the rising lake fixes it in the mid-fifteenth century, too early for that trigger. The toe of the landslide is still there, anchoring both the Cascade Locks built in 1896 and, at the pinch point, Bonneville Dam, whose reservoir drowned the rapids in 1938.","The steel-truss Bridge of the Gods — built in 1926, raised when the dam pool rose — takes its name from the old one, and stands roughly where the crossing held."]},{"heading":"The sacred narratives","paragraphs":["The oral traditions give the event actors. In the most-told version, the mountains were people: Wy'east — Mount Hood — and Pahto — Mount Adams — were sons of Coyote who both loved the maiden Mount St. Helens, and fought across a great bridge until Coyote brought it down to end the feud. Another telling names the bridge Tahmahnaw and gives the affair to a chief, Ka'nax, and two mountain princesses.","The file treats these the way the tribes do: as sacred narratives and oral histories, not ghost stories. The Bridge of the Gods dossier contains no haunting — what it contains is a catastrophe so large that the people who saw it built a legend accurate enough to check against the geology, and the geology kept confirming it."]},{"heading":"What remains","paragraphs":["What remains is the most legible legend in the archive: a drowned forest dated to the decade, a riverbed still shaped by the dam, a mountain face still scarred, and a toll bridge named for the crossing everyone remembered but no one could find — until the cores came back. The file's verdict: no ghosts filed, one mountain dissolved, and an oral tradition that out-reported the survey maps by five hundred years."]}],"name":"Bridge of the Gods — Bonneville Landslide","aliases":["Bonneville Landslide natural bridge"],"type":"LEGEND_LANDSCAPE","type_label":"Legend Landscape","cats":["LOCAL_LEGEND","STRANGE_NATURAL_PHENOMENON","INDIGENOUS","GEOLOGY","LEGEND"],"groups":["legends","unexplained"],"desc":"Columbia Gorge landslide landscape linked to Klickitat oral tradition.","full_desc":"Bridge of the Gods — Bonneville Landslide is a legend landscape in Washington.
