Identify me

I found a really interesting wildflower today while exploring around Echo lake with my son. It was growing in sandy soil in pretty close proximity to the water. Can anyone enlighten me?

My guess would be Turtlehead (Chelone glabra).

Looks like you nailed it, thanks! It seems it's used as a form of birth control? Hmm.
