YELLOWSTONE NATIONAL PARK, Wyo. -- A small earthquake jolted Yellowstone National Park near Old Faithful geyser on Sunday.
The U.S. Geological Survey says the 3.6 magnitude temblor occurred just before 10 a.m. with the epicenter located about 6 miles north of Old Faithful, one of the park's main attractions.
Yellowstone National Park officials didn't return a call from The Associated Press on Sunday.
A live video feed provided by the National Park Service showed Old Faithful erupting later in the day in front of several hundred onlookers.
