Kids from the same High School ranging in age from 14 to 18.
We did a weekend camp out once a month while school was in session and a two week canoe trip to Canada each summer.
What I saw was a positive change in each sex's view of the opposite.
These girls were tough, didn't shirk and pulled their share as much they were able. The guys learned a respect, and not a grudging one, for them and I expect, looked at them more so as equals than before.
The girls, while initially concerned, in pre-trip planning, about how the guys would behave out in the woods for two weeks, found instead that they were treated as part of the "team" and got help when needed, as did any member of that team.
From what I saw, there was just positive results from all of this.
