Previous week, dead Walrus carcasses were discovered on a northwest Alaska beach, and according to the US Fish and Wildlife Service (FWS), their deaths seemed to be natural. They were found near Point Lay, the same place where 35,000 walrus were spotted on shore September 2.

In a press release on Thursday, the agency said that an employee of the US Geological Survey gave an image of the walrus carcasses. The service mentioned that it has been analyzing the photo to find out whether the carcasses were new or old, and attempting to determine an age range of the walruses. After it, an investigator will have to give a confirmation onsite.

The service mentioned that there was probably no foul play as the carcasses were intact. The service hasn't given any details regarding the number of dead walruses.

Walruses united in massive herds can stampede if a polar bear, hunter or airplane approaches them. In the rush to reach the safe ocean water, young animals might get crushed. The carcasses of over 130, most of them young walruses, were counted following a stampede at Alaska's Icy Cape in September 2009. The cause of the animals' death at Point Lay was not found.

The US Attorney in Alaska has been observing the investigation of 25 walruses discovered dead that were spotted at Cape Lisburne around 100 miles southwest of Point Lay. A handful of personnel run an Air Force radar station in Cape Lisburne.
