Nature can sometimes be amazing.

Lightning acted more like a light brush above a rock formation at Blue Mesa.

A Department of the Interior Facebook photo likened the shape to a T-rex getting ready to chomp the rocks.

The photo was taken by Hallie Larsen of the National Park Service, according to the post.

Commenters said it looks like a heart-shaped balloon, "a cougar stalking its prey" or a snake.

The post said the weather was caused by monsoons that bring summer lightning and warned hikers and visitors to take precautions and keep an eye on the weather.
