The Buried Forest of Alaska's Kruzof Island: a Window into the Past

Seldom does one find a way to directly date a prehistoric volcanic eruption, but 11-year-old Blake LaPerriere opened such a door for excited scientists in Southeast Alaska.

Last September, Blake, his parents, and his younger brothers were exploring a beach on southwestern Kruzof Island, part of the Tongass National Forest landscape and just west of Sitka, Alaska, where they live. Blake investigated a deeply incised creek behind a pile of beach drift where he found a standing burnt tree embedded in a tall bank of pumice. He brought it to his family’s attention, asking “Do you think that’s from a volcanic eruption a long time ago?”

Curious, Blake’s father Zach took photos and sent them my way.
