From the Frontiersman.com:
Deep within Lake Clark National Park and Preserve, staff at a remote ranger station on the north shore of Telaquana Lake noted something amiss. Wolves, a mighty apex predator of the park, were seen scraping fish carcasses from the ice.
Though odd, the observation made sense. Wolves are opportunists and Lake Clark, situated at the headwaters of Bristol Bay, is flush with fish. Likewise, salmon make a relatively safe dinner. While moose fight back and can break a wolf’s legs, salmon simply flop or freeze.
