As I have said many times, there is no better place to shoot rust than in the polar regions. This is from a whale oil tank on Deception Island in Antarctica.
The cool thing about Moab, Utah is you can stay in the village and with less than an hour driving time be in some amazing places. On one side of the highway is canyons and the other side arches. This was made in Arches National Park. Great hiking, lots of places to photograph. You’ll need at least several days to capture the area properly. Sunrise and sunset are the best times obviously. The air is clear and if you get there late October to early November you may get a beautiful dusting of snow.
