I learned this at Cornell Outing Club weekends on the islands
in Lake George in the early 1960s, with the alternate choruses.
The singer's name was Adriane (?) -- anyone know her? Her other
party piece was Coltman's Web of Birdsong.

Dick Levine sings a NJ version.

Bill D., I too have the map, probably not the same as yours,
traced on onionskin paper by Jo Houghton. If there's any
interest, I could scan it in.
