Another scribbled note indicated she had nothing but berries to eat and no way to treat water.
So, she was willing to eat wild berries but not drink the water? I've seriously got to question her judgement on this one. I personally have got to be pretty darn certain about berries in the woods before I pop them in my mouth, wild rasberries, strawberries and dew berries are about it. Choke cherries too, but they're way too tart for me unless I'm making jam.
