Len ... go to RMNP.
Yellowstone is a shell of what it was. I went to MSU in Bozeman and would be in the park every spare moment to photograph. This was in the late 80's and early 90's. Elk were abundant. PRE-WOLF...
Now they are virtually non-existant. I saw a total of 15 elk in a 3 day trip thru the park... YES, 15.
The population is desamated by the wolves. Moose are gone, antelope are gone.... My good friend Don Laubach, of E.L.K. INC in Gardiner has seen the change first hand out his store front and has some amazing footage and stills of the kills....
Save your time and frustration.... Go to RMNP.
The only thing you'll see in Wolfstone is ... well you get the picture.
