The Arctic National Wildlife Refuge turned 50 this week and it's still as ruggedly beautiful as it was back in 1960 when President Eisenhower took the first step toward protecting the land and all the beloved polar bears and majestic caribou who live there.

Now it's time to give the Arctic a birthday present: permanent protection from Big Oil.

Tomorrow, Shirt.Woot will help the Sierra Club spread the word by hosting an Arctic-themed T-shirt "derby," a.k.a. the site's weekly design contest. You can participate by submitting your T-shirt design to Shirt.Woot, or by voting for your favorite. The derby begins at noon on Friday, December 10 and the winning shirt will be available for purchase the following Friday.

After you've had your Arctic fashion fun at Shirt.Woot, you can visit the Sierra Club's I Heart the Arctic site and tell President Obama that if he likes it, he should put a ring on it. (Read: He should commit to making ANWR a national monument.)
