Sometime in the middle of the last night, 12 climbers from the organization scaled Mt. Rushmore carrying a 75-pound banner. Once unfurled in the morning hours, the 65 feet by 35 feet wide banner showed an unfinished picture of Obama's face with the words, "America honors leaders, not politicians: Stop Global Warming.”
The banner managed to stay securely anchored to the side of the monument (something organizers said was done in a way to ensure no harm came to the landmark) for roughtly one hour before being cut away by park rangers. For more information, check out the Greenpeace statement on the stunt here.
