This took place in Aspen last winter.
There are people who can ski day and night long. I am certainly one of them.
One day I rolled out to the slopes in the late afternoon. The day was exceptionally good, and I was regretting missing first half of it. To extend my ski time I stayed until the final lift of the day. Once up, I waited until most people started their descent to have the slope all to myself.
However, at that point very gentle snowstorm started, which despite of being only moderate, made it difficult to navigate the route, and given that no one was skiing in front of me, navigation became very tricky.
I kept descending at a very low speed, caring less about speed, and more about staying on the ski track. There were many points when I had to choose a route, and was totally unsure about which one leads home.
In the end of the day I descended safely thank to Aspen's lifeguards. It turns out that lifeguards always descend last to make sure no one's left on the slopes after lifts stop.
Before taking the last lift it is always a good idea to ask staff about what to do if you happen to be the last skier on the slope that day. And if you are told that the day closing procedure is similar to that of Aspen's, and find yourself alone on the slope, then focus on staying on the ski track.
Hope this helps you,
