To find the northernmost point in Michigan, you have to take a boat or seaplane to Isle Royale.The island is the largest in Lake Superior and it's also home to Michigan's only National Park.The remoteness of the island, and the fact that the island is largely untouched by humans has made for a perfect place to watch nature take its course.Michigan Radio's Rebecca Williams and Mark Brush traveled to Isle Royale to meet the researchers who have been watching how wolves and moose interact for 54 years. The research project is the longest continuous study of any predator-prey system in the world.What researchers have learned on this natural island laboratory has informed ecological science around the world.

Wolf biologist Rolf Peterson taking us to the site of a moose carcass on Caribou Island. He and other researchers collect bones from dead moose as part of their research.

It's not as gross as it sounds. And if you heard yesterday's report from Rebecca Williams, it really does sound gross.

The wolf-moose research project on Michigan's Isle Royale National Park is in its 54th year.

A big chunk of their research goes into tracking down dead moose - bones and carcasses - around the island.

From these remains the researchers can pick apart the status and overall health of the moose population. And understanding moose is important to wolf research, since the wolves eat the moose.

It's like understanding the overall quality and quantity of food available at the grocery store. If there's good, abundant food available, you'd expect things to be good. If not, well - you get the picture.

When Rebecca Williams and I arrived at the Daisy Farm campground on Isle Royale, we were met by Rolf Peterson in his boat.

He said he'd just heard of a dead moose on Caribou Island and asked whether we would like to go see it with him.

A stroke of luck. We'd traveled by plane, car, and boat to get here, and here was our chance to see Peterson in action.

Here's a video of our trip with him. Is ripping the skull off a dead moose gross? I didn't think so, but you can be the judge.
