On June 11, a massive landslide in a remote part of Glacier Bay National Park produced enough of a rumble to trigger a seismic signal of 3.7-magnitude on earthquake monitors in both Alaska and Canada. The 5.5 miles long slide was one of the biggest ever seen in North America. However, the extent of the slide wasn’t known until last week when a bush pilot flew over the park and snapped a few photos of the collapsed cliff face in the remote unnamed valley. Marten Geertsema, a research geomorphologist for the provincial forest service in British Columbia, says “”… If someone was trekking up this glacier when it happened, they would have been toast.”
