Yeppers, it does look like a copperhead, but like you, that's one of the widest heads I've seen on one. With the lousy pic, it could'a been quite a few different breeds. ANY time I see that diamond shaped head, it's venomous as far as I'm concerned. That's why those Northern water snakes have scared the bejeebers out'ta me before! There was no mention of what effect the bite had on the lady, so I was assuming it was a non-venomous snake.
