When was the last time you had to reroute your hike because of a whale carcass? That's the situation at Glacier Bay National Park, where the remains of a humpback whale have come ashore and turned into a magnet for bears and other scavengers.

The remains were floating about the Scidmore Cut area in 2010, and recently washed ashore north of the Geikie Inlet, according to park officials. Park Service employees are monitoring the remains, and the bears gorging themselves on it, to determine when the shoreline can be reopened to hikers and overnight camping.

Park officials point out that not only is it a crime to disturb wildlife, and that boaters should avoid getting so close to the shore that the scavengers alter their behavior, but also note that it's a crime to remove whale bones under the National Park Service and Endangered Species Act regulations.
