I can really appreciate your article because it reminds me of my childhood.
I have some Northern Cheyenne heritage in my family and live on the border of the Northern Cheyenne Indian reservation in Montana.
When I was young about grade school age, we used to go on some "expeditions" we called "foraging".
We would gather many different types of wild foods or remedies.
Some of those that I can remember are:
"Blackroot" - Used as a tooth ache medicine. It actually numbs your mouth kinda cool we used to try it just for kicks.
Yampa we also called them wild carrots, Turnips, plumps, Chokecherries, Buffalo berries, ground cherries, Wild Onions, Mariposa lilly, spinach.
I believe there were many others that I have since forgotten and sometimes think I should re-start this yearly tradition so that my children can look back upon it and maybe decide to pass it along to their children.
