The littleleaf mock-orange image was shot on Spruce House trail at Mesa Verde. I don't know if the Anasazi ate mock-orange fruit. There is an item that mentions them being eaten by the Isleta Pueblo. This seems a little strange since the fruit is a dry capsule. Perhaps it was eaten unripened. In very early days, Indians ate various dry fruits and barks, ground up into meal. The hard parts, even nut shells, were ground with the rest. Eating this caused a lot of wear on teeth. Skulls of older Indians (in those days 30 was pretty old) show a lot of wear. Eventually that type of food was replaced by cultivated food like corn and pumpkins, and Indians traded in tooth erosion for tooth decay.
