Colorful Photographs That Reveal The Beauty Within Deformed Frogs

Based in New York, visual artist and biologist Brandon Ballengée has combined his love for art and science with these colorful photographs of deformed frogs. 


Inspired by his scientific research, which was about the decline of frog populations due to their deformities, Ballengée colored his specimens with chemicals, and then used a high-resolution scanner to create photographs of each deformed frog. 

The artist chooses to show the beauty that can be found within these creatures as he did not want to exploit their deformities. In these prints, these frogs appear to be as large as toddlers to evoke empathy—if they were too small, viewers would dismiss them. 

Aptly named “Reliquaries”, these images are a tribute to the short lives of these amphibians. 

Ballengée’s works will be exhibited till 13 April 2014 at the Alden B. Dow Museum of Science and Art in Michigan.

The deformation in the Grand Canyon

These are the same two units I showed in the last post moving up the Grand Canyon, but the setting in this photo illustrates an important part of the story; the deformation.

These rocks record the building of what was once a mighty mountain range that has now been worn away. In this photo, the Zoroaster granite and the Vishnu Schist are seen in their typical state.

The schist was once sedimentary rock trapped in a continental collision. The granites intruded them, heating and recrystallizing them to metamorphic rocks. Meanwhile, far above these rocks, mountains were being built. The pressures of the mountain building process twisted and folded the hot rocks deep below.

Similar features are observed in the deepest parts of many mountain ranges when they are exhumed; twisted layers of granite and metasedimentary rocks. The directions of the folds vary somewhat but they generally record the direction that the rocks were moving, constraining the impact of an island arc with the continental mass to the North.

The ages of the deformation in these rocks vary from 1.70 to 1.68 billion years ago (a 20 million year pulse of mountain building!).

These rocks started at the Earth’s surface, were buried 20+ kilometers deep, and then within the next 100 million years brought back close enough to the surface to stop the metamorphic processes. A truly twisted path!
