There's an elk that I keep saying "maybe next year" about. I got into a herd one day and one of the calves was very dark in color. It was that dark charcoal gray (black-ish) color. No idea if it is a cow or bull. I've been trying to find it again. Since I'm not seeing it with the herds, I'm assuming it is now a young bull that is on his own before re-entering the herd. Although, with so many cougars I think I know the actual outcome. Keep hoping to cross paths with it again. A few years back there was a cow in a herd about a dozen miles away that had a similar color, but not as dark. Maybe this year, maybe next year.
