Winter whiteout

I always wanted to photograph Monument Valley in the snow. It doesn't snow often, and to have a virtual white out here is quite rare. I lived in L.A. at the time, and I checked the weather every day during the winter. This was pre-Internet in the early 90's, so I had to call the National Weather Service to hear their recording. Finally, I heard a winter storm was approaching so I drove 15 hours overnight to get there. I arrived at 6am, and this is what I saw. I was the only one there. The snow on the road leading to the visitor center was pristine -- no tire tracks or footprints at all before I arrived. At the time, I was shooting medium format film (a Mamiya 7 for this photo), and I used a handheld Sekonic L-358 light meter (on incident mode) to determine the exposure. The lens I used was a 45mm -- equivalent to about a 21mm in the full frame 35mm digital format. I don't remember the shutter speed -- it was probably 1/8 -- but my aperture would have been f/32 for sure. I shot with Fujichrome Velvia 50, and I used a tripod all the time back then. Within an hour, the fog lifted and the sky was blue. After another 90 minutes, much of the snow was already melting and the magic was gone.
