The golden eagle is one of the best known of the birds of prey found in the Rockies. It is dark brown in colour. Bald eagles frequent the Vermilion Lakes area as well. They are dark brown as well as juveniles, but develop a striking white head and tail when they reach sexual maturity at about five years of age. A striking feature of this peak is, "The Goat's Eye" located on the northeast ridge and visible as one travels up Healy Creek. This natural hole in the mountain was first noted by George Simpson who wrote of, "a very peculiar feature in an opening of about eighty feet by fifty, which, as we advanced nearer, assumed the appearance of the gateway of a giant's fortress."
