Question 1

1. How were these long ridges created and who was responsible?

Location
Grand Mesa, Colorado, USA
Photographer
Sandy Reed
Answer

These are all pocket gopher eskers. Eskers are narrow ridges of packed soil that appear on the ground surface after the winter snow melts. They are made when the pocket gopher excavates soil from beneath the snow and pushes the excess soil into the tunnels they’ve made within the snow itself. When the snow melts, these sediment-packed tunnels remain and become visible.

Question 2

2. How was this track created and who is responsible?

Location
No exact city/town, none, South Africa
Photographer
Sandy Reed
Answer

The folds of the skin can be seen in this picture of a zebra dust bath or roll. Zebras dust bathe to rid themselves of ticks, flies and parasites. It also helps keep them cool. Zebras often dust bath as a group and this is considered part of their social behavior.

Question 3

3. Who is the maker of these tracks?

Location
Rwanda
Photographer
Sandy Reed
Answer

These are very fresh tracks (made minutes before the photo was taken) of the knuckles from a mountain gorilla in Rwanda. Sandy Reed was hiking in Volcanoes National Park with a guided group and saw the track just before seeing the gorilla. Mountain gorillas walk by flexing their fingers inward, tucking them into their palms, and placing the weight of their bodies on the dorsal surfaces of the middle finger bones (the middle phalanges) – their knuckles. This allows them to keep their long fingers free for grasping and climbing trees as well as providing a stable way to move on the ground.
