Scammell played on the blueline for Nova Scotia champion Northern Subway Selects.
The Selects earned a silver medal at the event, losing 2-0 to P.E.I. in the championship game on a late third-period goal, followed by an empty netter.
Goaltender Lily Currie, of Masstown, made 23 saves for the Selects in the gold-medal game.
It was the Selects first appearance at the Atlantic championship. They earned their berth after winning the Nova Scotia title over Metro Boston Pizza.
The Selects opened the tournament with a 3-2 win over P.E.I. on Thursday, before a 5-3 triumph over Moncton Rockets on Friday. They defeated host East Hants Pro Cresting Penguins 7-2 Friday night before outscoring Newfoundland and Labrador 6-4 on Saturday.
Scammell and Currie were among four Colchester County players on the team. Others were defenceman Lindsey Smith (Masstown) and forward Maddie Quinn (Truro).
Scammell will attend University of New Hampshire (NCAA, Division 1) next fall.
