The impact zone was further exposed to a gigantic flotsam and jetsam torrential slide, trailed by the evidence of various lahars and pyroclastic streams. The major physiographic historic points on the guide incorporate the westbound depleting North-and South Forks of the Toutle River, Spirit Lake, and Johnston Ridge.
