It all depends on the snow conditions. In 2014 the cuts were packed full of wind blown snow but the ground was bare in many places. Walking to the photo locations wasn't difficult and where there was snow there was a good crust to walk on.
In 2015 we had one to two feet of snow pretty much everywhere and the cuts didn't have any more snow in them then the level ground. We walked in great circles around and ahead of the train to get to the runby location. There were a couple of people with snow shoes and if you followed them you didn't break through (at least most of the time!). Otherwise some poor soul had to break trail and if you were 5 or 6 back, things weren't too bad!
In 2016 there was no snow until we started getting near Sublette and then it was in areas shaded by trees. To get to the photo line sometimes we had to walk through the woods. Brush hidden under the snow could make it a struggle in places. The runbys tended to be shorter!
I suggest that anyone who has snow shoes bring them but we probably only need a half dozen people with snow shoes to break trail, if they are needed at all. Getting 45 people onto snow shoes, out to the runby and back on the train would take 45 minutes per runby!
Here are some shots from the previous 3 trips chosen to show snow conditions
