Here is one shot that I am particularly fond of. We hiked to the top of a mountain through a small, unmarked trail system in a more remote area of the park. This scene was what we saw through a small cut through the brush and trees at the summit.
Taken with the Nikkor-T 720mm f/16. This lens is one I rarely have reason to use but when I do, it's always stunning. I believe I stopped down to about f/32. Taken with Provia 100F film:
