She won on the uneven bars with a 9.55, finished fourth on the vault (9.50), fourth on the beam (9.40) and sixth on the floor (9.00).
Snyder, a member of the Hill's Angels, said she has the benefit of experience.
"If I do something wrong, I know how to recover," said Snyder, who will attend the University of Oregon on a gymnastics scholarship next year.
Hill's Angels coach Kelli Hill said, "She's not in peak situation for international competition, but she is going to be a good college gymnast."
Snyder's teammate Wendy Wheaton, 11, also made her mark at the event, which included teams from nine middle Atlantic states. Wheaton was the overall junior champion and qualified in three of the four events last night, winning the beam (9.50) and finishing in the top three in the bars (second, 9.50) and the vault (third, 9.55).
Paula West, of Gym Starz, won both the vault (9.70) and the floor (9.70) last night.
Miriam Pourshoushtari, of Hill's Angels, finished in the top five in the floor (fourth, 9.20), the beam (third, 9.40) and the bars (fourth, 9.45).
Local favorite Carolyn Hecht, 13, who is a member of the host team, Rebounders, also qualified in three events.
The compulsory events in level 5 will start at 9:30 this morning at the Towson Center. Levels 6 and 7 will compete at 1:15 p.m.
