The 2013 Stretch Student Saga: A Change in Course

Joseph Blumberg

Professor Carl Renshaw and 11 students just completed an unanticipated venture into the flood-ravaged canyons of Boulder, Colo. This was a detour in their 10-week off-campus odyssey known as “the Stretch.” Their original destination—the national parks—had been rendered inaccessible by the Federal government shutdown.

In a period of eight days, from September 9 through 16, Boulder experienced more than 17 inches of rain, amounting to what the National Weather Service called a 1,000-year rain, causing a 100-year flood. Houses were toppled and cars were carried away by the raging torrents rushing through the Colorado canyons.

Dartmouth Scientists Study Irene’s Impact to Predict Future Flooding Hazards

The devastation recently wrought by Superstorm Sandy reawakens memories of Tropical Storm Irene, still fresh in the minds of many Vermonters. Irene’s legacy is evident in ruined rivers, shattered homes, and historic covered bridges washed away. Perhaps more unsettling is the prospect of more to come, say a pair of Dartmouth professors who are studying the damage Irene left behind.

“There is no smoking gun here that directly associates Irene with global warming, but all the climate models suggest that storms like Irene and Sandy are going to increase in intensity, magnitude, and frequency,” says Frank Magilligan, a professor in the Department of Geography at Dartmouth.
