Weekly Photo Challenge: Delta

Δ Delta

“This week, share a photograph that signifies transitions and change to you… Explore the ways in which a single photograph can express time, while only showing us a small portion of any given moment.”

Time and change symbolized in a static, 2-dimensional image — not an easy trick. However, all around us there are clues to the way that Nature has changed things over time.  How about:
1) The resting place of the bleached pelvic bone of an elk who once wandered this tall grass prairie in South Dakota

2) The abstract art of calcite deposits left in a cave long after limestone has dissolved  

 3) The fossilized bones of dinosaurs that roamed the Earth some 150 million years ago, exhibited for present day tourists to see and touch

4) These stately forms of sandstone, layered and eroded over time 

5) The moment in time when light, air, water and Earth meet in a colorful conjunction, only to disappear in the next movement of the elements

Of these five examples, which one speaks to you of the joy in change and movement?
