Seven years ago, a 1,200-square-mile iceberg broke off from the Antarctic ice shelf. For a few years the 71-mile long berg was the world’s biggest free-floating object — larger than a supersize cruise ship, imagine that.

Scientists being scientists, first they named it and then they put some seismographs on old B15A. In October 2005, like a Japanese glass float slamming into the seawall, cowabunga, B15A turned into a raft of itty bitty ice cubes when it rammed into the Antarctic coast. Huge Continent: 1, Big But Not as Big Iceberg, O.

And ya know what caused that ’berg to go bye-bye? Us. Well, OK, not we Alaskans, but the Gulf of Alaska, She Who Scares Even Otherwise Fearless Mariners. Some scientists from the University of Chicago and Northwestern University backtracked the storm that caused B15A to hit the coast and break up into itty bitty bits and figured out waves from Gulf of Alaska storm traveled 8,000 miles around the world. Sooner than you could say “Holy Molly Brown,” 40-foot seas rippled south, pushed B15A up against the coast and ripped it to shreds.

Forces that one day could dump tons of heavy, wet, sloppy snow on your driveway and then the next day evaporate it into steam can easily devour a puny little 1,200-square-foot hunk of ice. Make a big enough splash, and even from here, you’ll be noticed. See? And you thought nothing happened in Homer. As the Betster likes to keep pointing out, there’s lots going on even when there doesn’t seem to be much going on, like these Best Bets:

BEST BODETT THAT TRAIL: In the Get ’Er Done department, the Kachemak Nordic Ski Club trail breakers work so fast sometimes they get the trails set before the roads get plowed. Friday from 7-9 p.m., they’ll leave the light on for you with night skiing by Tiki torches at the Baycrest Ski Trails. Headlamps suggested, though. A fund-raiser to pay for the Diamond Creek university property, a $10 donation is asked. Meet at the Sterling Highway trailhead by DOT.

BEST WELCOME TO THE NABE BET: Homer’s artist community keeps getting bigger and bigger. Greet the latest group of new artists from 5-7 p.m. Friday at the Homer Council on the Arts Emerging Artists show. Take a stroll down Pioneer Avenue or over to Old Town to see other First Friday shows.

BEST BEAUCOUP BABES BET: That’s “beaucoup” as in talent for the Bacot Basement Babes Jazz Harp Trio. JulieAnn Smith, Italian harp and keyboards, Marjolein Condon, bass, and Karen McCarthy, vocals and percussion, perform jazz standards, rock/blues and jazz originals by JulieAnn Smith from 7:30-11 p.m. Friday at Kharacters on Pioneer Avenue — the perfect way to cap off First Friday.

BEST FTL BET: That’s faster-than-light, which is about the speed of the Mariners’ cross-country ski team. These racers go so fast not even our sports guy’s fancy Nikon digital camera can snap their pix. Check out the borough XC ski races starting at noon Saturday at the McNeil Canyon ski trails.

BEST BIG BLUES BET: Terry Robb is the classic blues musician. While lightweight talents get all the glory, he’s been plugging away year after year, playing with some of the best musicians in the world. This weekend the Portland singer-songwriter-guitarist gets the spotlight at The Alibi, when he plays starting at 10 p.m. Friday and Saturday.

BEST WOMEN IN SILLY COSTUMES BET: Sunday at 1:30 p.m. it’s not just a ski of women, it’s the Ski for Women, which means along with ladies in wild costumes, there will be guys there showing their support — hey, maybe some guys in silly outfits, too. A $15 donation supports South Peninsula Haven House, the organization that helps families who are victims of domestic violence. Meet at the Lookout Mountain trails on Ohlson Mountain Road.

BEST FIRST TUESDAY BET: Our art scene is so hip we need another day to celebrate. If you didn’t get enough art on Friday, check out the Pratt Museum on Tuesday starting at 5 p.m. It’s the annual meeting of the Homer Society of Natural History and the opening of Robert Glenn Ketchum’s photography exhibit, “Southwest Alaska: A World of Parks and Wildlife Refuges at the Crossroads.” Michelle Ravenmoon of the Lake Clark National Park Service also speaks.
