Sick of frittering away your hard-earned wages on March Madness? How about betting on melting ice instead?
An annual contest to guess the exact moment the ice breaks on the River Tanana, 300 miles north of Anchorage, is attracting global interest, both as a chance to win a $300,000 (£151,000) prize and as one of the world’s most precise scientific indicators of the effects of global warming.
Betting closes at midnight on April 5, and tickets are sold throughout Alaska.
