Best of the U.S.: Lindsey Jacobellis, Faye Gulini and Jackie Hernandez.
Best of the rest: Maelle Ricker and Dominique Maltais of Canada, Eva Samkova of the Czech Republic and Helene Olafsen of Norway. Ricker, the defending Olympic champion, broke her arm in training and had surgery in late January but still hopes to compete.
U.S. chances to medal: Jacobellis, riddled with injuries, showed she remains a major factor in the sport with an X Games win in January, her eighth gold medal at that event.
Little-known fact: Hernandez shares a passion for motorcycles with her father. They ride Harley-Davidsons together.
