45 YearsAgo: Mount St. Helens Eruption Caught on Camera – May 18, 1980 At 9:20 AM, USGS scientist Don Swanson captured the unthinkable: a towering, rotating ash column rising from a massive lateral blast—the summit gone, the landscape transformed. ⚠️ A dark, twisting helix of ash, lightning within the plume, mudflows racing down slopes, forests flattened.
