Redoubt 450 yBP
Start: 450 yBP [1]
Stop: 1800 [1]
Event Type: Explosive
Description: From Beget and Nye (1994): "A prehistoric pyroclastic flow deposit is exposed between two horizons of till in a stream cut through moraines just west of the piedmont lobe of the Drift Glacier (Fig. 1 [in original text]). The 1-2-m- thick flow rode up a steep, 10-m-high slope cut on the older moraine, and is truncated and buried by a younger moraine. These are the innermost moraines of the Drift Glacier, lying only a few hundred meters beyond its current border. They were probably deposited during the Little Ice Age of the 16th-19th century, so that the intercalated pyroclastic flow is also probably only a few hundred years old."
