ANCHORAGE, Alaska, June 26 (UPI) -- U.S. biologists have reportedly built a 250-foot-long fence to stop walruses from plunging over cliffs above an Alaskan beach. About 30 bull walruses plunged to their deaths onto a Bristol Bay beach last year, Rob MacDonald,ugg classic 5825, a biologist with the Togiak National Wildlife Refuge, told the Anchorage (Alaska) Daily News. The deaths seem to occur only at Cape Peirce, where thousands of walruses sometimes gather to rest between meals, MacDonald said. He said if too many walruses crowd onto the quarter-mile-long beach, dozens walk up a chute to a grassy plateau. Then, when it's time to feed, the animals -- which have poor eyesight -- seem to make a beeline for the water, which leads them across the plateau and over a cliff that's about 150 feet high, MacDonald told the newspaper. Sand dunes used to block the chute, but the 3,000-pound walruses,UGG Classic Metallic, with help from the wind, wore away the dunes. The $2,ugg boots sale,500, 3-foot-tall, fence is expected to work as a snow fence, creating sand dunes up to 16 feet high, MacDonald said, keeping the walruses from straying to the plateau.Related articles：
