Best of the U.S.: Arielle Gold, Kelly Clark, Kaitlyn Farrington and Hannah Teter.
Best of the rest: Defending Olympic champion Torah Bright of Australia.
U.S. chances to medal: The ageless Clark, at 30, will be competing in her fourth Olympics. Gold has a decent shot to make headline writers very happy.
Little-known fact: Chloe Kim, the best female snowboarder in the U.S. this season, is ineligible for the Olympics because she is too young. The Southern Californian is 13 and became the youngest medalist in X Games history.
