The closest I can come to that is archeology field school. Sweat lodge next to mountain stream on a gently sloped aspen grove. A dozen college students of both gender, lots of alcohol and other relaxants... and nothing else to do on your days off.
Eucalyptus oil-laced water dripped on hot stones right out of the fire. Everyone naked, sitting cross legged around the rocks steaming in a cast iron dutch oven. When you were on the edge of passing out, the flap was flung open, bodies flew out and jumped in the ice- cold stream to whoops and laughs.
Ghod I miss being young!
