Edible Wild Plants

We went hiking as a family today at the wildlife refuge. We saw a lot of wildlife including a herd of buffalo, a weird lizard and an elk. We climbed/hiked to the top of Elk Mountain. And I was able to identify ten sources of wild edible plants:
Dandelion
Barrel Cactus
Prickly Pear Cactus
Wild Onion (harvested a lot)
Common Juniper (made almost iced tea)
Pine
Cattails
Long Grasses
Oak (acorn flour)
Hickory

I also ordered a copy of the Reader's Digest - Back to Basics book today, I really look forward to its arrival in the next 7-10 days.
