The campground suggested we go right across the street to Mesa Verde NP and get some info.
The dwellings are very impressive. Although they have been massively re-constructed and repaired since they were first discovered.
So we have a pretty sweet view.
Yucca plants can fruit! They don't seem to do it every year but they do fruit and you can eat them. However they don't ripen until the winter when they turn sweet.
The ranger says you could find yucca fries if you look around local menus. We never saw them or I would have tasted them.
It is awesome, we have been eating it at least once a week.
