Debris from last year's tsunami in Japan is apparently starting to appear on Unalaska's beaches.

While the pieces tend to be small and unremarkable after a trans-Pacific journey, the sheer quantity makes it "highly probable" that they were generated by the giant waves that walloped the Japanese coast, said David Gaudet of the Marine Conservation Alliance, which is tracking the debris.

Occasionally a very distinctive object with Japanese markings, like a soccer ball, washes ashore in Alaska, but those are the exceptions, Gaudet said. In Unalaska, local resident Charlie Medlicott reported finding a bottle of Japanese carpet shampoo near the gun range by the airport, along with other likely objects.

The stuff isn't necessarily of tsunami origin, perhaps it fell off a merchant vessel. But the quantity he's seeing points to the tsunami.

While the city of Unalaska faces the Bering Sea, trails lead to the Pacific side of the island, a roundtrip day hike from town. Right now, though, snow's still making trail access difficult, he said.

"I think the first people to get out to Ugadaga Bay are going to find all kinds of stuff," Medlicott said.

Caleb Peterson, with the Coast Guard in Unalaska, found a glass net float wrapped in twine along Summer Bay Road, another candidate.

Unalaska beachcombing enthusiast Nick Butryn found a plastic gas container with Asian lettering, another definite maybe. Or not? "You can't really date it. It could have been floating in the ocean for five years," he said.

Butryn routinely observes rich deposits of plastic on local beaches, much of it generated by the commercial fishing industry. He takes home some of the flotsam and jetsam and attaches it to a small pallet, a work of art in progress.

He's still searching for one classic Alaskan beach treasure: I'm looking for that elusive glass ball," Butryn said.
