|Canyons & Hills - Death Valley 1973|
So I'm looking at these tiny little images on my contact sheets, printed in 1973, and unfortunately there's no way to establish any chronology. One contact sheet has about 5-6 film strips on it, with about 4-5 images per strip. So, you can assume that adjacent images were taken more or less at the same time, but it's clear that film strips from different rolls of film can be shown on the same contact sheet.
Also, I was always mindful of the fact that I had a limited amount of film so there's hardly any "establishing shots." As a consequence of these factors I'm thinking that the above photo was probably taken in Death Valley, but it might be Owens Valley.
