DDB The pine tree in one of the shots that was used to speculate about the clouds being similar looks to me to be quite different in detail (granting the different lens FL's). Enlarged details would nail that down as would the snow patterns. They would have to be identcal if they were made on the same day. Perhaps a diary or other notes (other than the envelopes in question) could confirm the dates he was in the area. I have seen examples of AA's early work in the area and there were washed out snow highlights and muddy blacks. One would think any sensible photographer would bracket shots.
