USGS capturing glacial decline in Glacier National Park through repeat photography

Glacier National Park Decline

From USGS  --  Climate change research in Glacier National Park, Montana entails many methods of documenting the landscape change, including the decline of the parks namesake glaciers. While less quantitative than other high-tech methods of recording glacial mass, depth, and rate of retreat, repeat photography has become a valuable tool for communicating effects of global warming.

Yellowstone's Steamboat Geyser has rare eruption

Yellowstone National Park's Steamboat Geyser — the world's tallest — has erupted for the first time in more than eight years. On July 31, 2013, the nine-minute blast sent steaming hot water an estimated 200 to 300 feet in the air. Unlike the park's popular and famous Old Faithful geyser, which spews water like clockwork every hour-and-a-half, no one knows when Steamboat will erupt next. In the past, it's gone as long as 50 years without a major event. In 1964, it erupted a record 29 times. The last blast came in 2005.
