Earthquake Point

Earthquake Point, 2 miles north of Entiat on Highway 97 Alternate

The sign below this point reads,

This site on Ribbon Cliff, called Broken Mountain by the Indians, experienced a violent earthquake in December, 1872. The shock split the mountain, forming the cliff to the west and causing a huge rockslide which stopped the flow of the Columbia River for several hours. The black ribbons of the cliff are lava-filled fissures. Plateau of the region later covered the rock mass. The white volcanic ash in road excavation is so recent as to have buried undecayed logs. It was blown from Glacier Peak, a volcanic cone, 50 miles to the northwest
