A lot of great things to chose from!
Third: A wide range of elements: Rock, water, trees. Round shapes & edges. I like the framing & the left mining equipment which I hadn't seen were it not for the title.

Second: Man vs nature? Powerful forces at at play. I like the perspective & placement of elements in the photo, and it has a kind of 3D like effect built in.

First: Stunning spiral-like structures met my eye first. Vibrant colours. What am I looking at? Coming from the cold North, I'm not used to canyons. This is a beautiful portrayal, and thus the winner was found

I think the three photos shown next to each other vertically form a nice flowing of forms & colour changes. Earth, rocks, water and fire.
Vertical elements, and elemental verticals.

Over to you, Jola - and thanks again all for participating
