While Grizzer and Denali are different subspecies, their full winter pelage can make it hard to tell them apart.
Explore.org viewer Michel-Switzerland provided this insight on identifying them on the Center’s webcam. Thanks to Explore.org viewers “Keli loves Cats” a “Mark58” for their screen captures of Grizzer and Denali.
Denali has more fire-brown tones on the back, Grizzer is more grey and has a well marked black stripe in the middle of the back between the light of the neckline and the grey of the lower back.
