Jump-off Joe was a massive 100-foot-tall sea stack geological formation composed of middle Miocene concretionary sandstone at Nye Beach in Newport, Oregon. It was a well-known tourist attraction before World War I. It formed sometime before the 1880s when it was connected to the mainland and was a major impediment walking the beach. Early travelers would have to jump off the side to get over it, hence the name. Early writers claimed the site was connected with Native American mythology. Erosion separated it from the mainland in the 1890s, possibly accelerated by the construction of jetties at Yaquina Bay, and its large arch collapsed in 1916. Between 1920 and 1970, the majority of the sea stack collapsed, and by 1990 it had been swept away, and little trace remains today. A series of pictures that show the gradual demise of the sea stack is here. Click here to download the CoastView app and explore Nye Beach and the Oregon Coast.
