On July 24, 1993: a 100-acre (0.4 sq km) swath of land failed and slid into the Snake River, temporarily blocking it and permanently diverting it southward. Travel to the scene of this recent geologic event with geology professor Shawn Willsey. Take in the entirety of the "Bliss Landslide" (actually an earthflow) from the south before journeying out to the margin of the slide to examine the material that failed. Finally, head down to the toe of the slide to investigate the 50,000 year old lava dam and pillow lava that tie into the story.
