Hi, say i live in Montana and try to go to Yellowstone once or twice a year. Check out www.yellowstoneassociation.org also 406-848-2400. If you like you can get in on a group tour or private tour for a cost. In Feb they have 1. Wolves of Yellowstone 2. Winter photography in Yellowstone 3. Three dog day 4. Coyote and Raven 5. Wildlife Photography and it goes on. While on these tours you will see other animals.
ALL vehicles including snowmobiles stay on trails and roads. You don't just take off in Yellowstone. You will make the Rangers mad at you. The majority of your pictures will be from or very close to a road. If you are taking your car or truck, 4x4 i hope, you can drive into the Lamar Valley and get great pictures. The Lamar is active in Feb for wolves. Tatonka, as we call them, will also be in the area.
Snowshoes??? Can you out snowshoe a buffalo, wolf or Griz?
I see you have a 600mm, great, you will want to take it with you. I would put that on one body and the 70-200 on the other, you will be ready!
My summer picture in Yellowstone i added was taken with a D3s 200-400VRII with a 1.4 added. Hand held braced against a tree and about 20 feet from my vehicle. Remember they can run 25+ MPH.
Have a GREAT time.
