Intrigued, Haeussler recruited Rob Witter, whom he met at the Chile conference, to join his team at the USGS Alaska Science Center in Anchorage. (Witter was to be part of the team at Allison Lake but suffered a broken collarbone in a recent mountain bike crash).<\/p>\n\t\t\t\t
At Allison Lake, after acquiring a “fantastic grid” of mini seismic data all over the lake, the scientists hiked back to their Arctic Oven for the night.<\/p>\n\t\t\t\t
The rain did not stop. It got so heavy that Haeussler’s Valdez contact called him and recommended his team leave their campsite as soon as possible. The steep gravel road to the highway was eroding so much it would become undriveable soon, he warned.<\/p>\n\t\t\t\t
With night falling, Haeussler and the team decided to leave the next morning after securing their gear by the lakeside for retrieval later.<\/p>\n\t\t\t\t
The next day, creeping along in the truck, they made it back to the Valdez highway, and after seven hours, back to Anchorage. With them was a laptop with information about the old and ancient earthquakes that rocked Allison Lake and maybe all of Prince William Sound.<\/p>\n\t\t\t\t
With that evidence, and that from other lakes they have probed such as Eklutna and Skilak, they are writing a history of Alaska earthquakes, old and new.<\/p>\n\t\t\t\t
