The Study Of Groundhogs: A Real Life Look At Marmots

This short documentary explores the groundhog research center in the Rocky Mountains of Colorado. Produced for Sony Home Entertainment's 15th-anniversary edition DVD of the 1993 film Groundhog Day, the program was filmed on location in the silver-mining ghost town of Gothic, Colorado, near Crested Butte. The Rocky Mountain Biological Laboratory has been located there since its founding in 1928.
