The Hoodoos At Sunset
This is the colour version of the black and white one.
The Formations
Hoodoos are spire like rock formations that are caused by the erosive forces of water and wind over thousands of years. These sandstone pedastals are capped with an erosion resistant (moreso than the sandstone) shale. Within the column you can see the stratigraphy of various layers. Over the ages the sandstone has eroded at a pace much faster than the overlying shales, creating a plateau on the top of the Hoodoos.
The Photo
From experience, the colour of the badlands rock changes witht e time of day, from pale grey's in the mid afternoon to burning yellow, orange and browns in the sunset. The texture of the soil and rock is readily available in this photo as you cn see the parched cracks in the base.
In the background you can see the typical badlands stratigraphy. The layering of cretaceous and tertiary sediment that were laid down millions of years ago. Hidden within those bands of rock is greyish layer, known as the KT Boundary, a boundary rich in irridium and also a layer that marks the end of the reign of reptiles. Depositied approximately 64 million years ago. This layer is found worldwide.
