Great pic!
Unusual colored animals are extra interesting.
I've seen two odd colored elk in my lifetime. One was an all black cow in Idaho about 40 years ago and the other was a platinum blonde bull that I shot in British Columbia in the same decade. The bull was so old that his remaining teeth were worn to the gums, and I assumed that he was somehow bleached out with age. The hair on his neck was the same platinum blonde color and same short length as over the rest of his body.
In addition, four years ago there was a copper tinted young bull on the West End of the Olympic Peninsula. He was a normal looking elk except that he was shaded toward a copper red hue.
