High waters in Yellowstone National Park and the Madison River are forcing bison to wander outside the Park's boundaries -- and Montana officials are working to push them back via hazing.

Rains and spring runoff is causing flooding throughout the greater Yellowstone region, causing officials to warn the public to be careful as they travel through the area.

Bad weather led to a drop in Yellowstone National Park attendance from May 2009 when compared to May 2010, but don't be concerned: the 2010 numbers are up overall, and the May 2010 final tally is still the fourth-best in Park history.
