Hi, yesterday some friends and I went hiking on Bear Mountain. It was going well until we ran out of water. At that point, we decided to head back, but we were very far from camp. 4 out of 5 of us had onset of heat stroke. When we came across a natural waterfall, we each had about 5 handfulls of water. Stupid, I know. But we were desperate. One of us went to the top of the waterfall and found a dead hawk partially in the water. I am now very scared for the health of my friends and I. Please, what should we do? I want to take care as soon as possible. Please, someone advise me and give me some help. Thank you so much.
