From the Hall of Disjointed Memories, Part 25: One More Loving Look at the Nokhu Crags | Never Summer Range, Rocky Mountain National Park, Colorado, USA
(Updated May 23, 2034)
Looking east-southeastward.
In a sense, this final shot in the series supplements Part 19 of this set, which shows Nokhu Crags from a much higher altitude. This photo was taken from the trail below Lake Agnes.
The sawtoothed arete pictured here is composed of Late Cretaceous Pierre Shale that has undergone contact metamorphism into hornfels by the magma of the nearby Mount Richthoften intrusion.
I'm fond of this chiaroscuro shot because it shows that the great mass of bedrock and talus above a terminal moraine clothed in a the stand of Engelmann Spruce (Picea engelmannii) still mostly retains the shale's original dark-gray color, but with a faint purple blush added.
The fine-grained sediments that make up the Pierre were deposited in the Western Interior Seaway. This extensive foreland basin developed eastward of the mountains of the Laramide Orogeny. The Seaway stretched from the Arctic to what is now the Gulf of Mexico.
You'll find the other photos and descriptions of this series in my From the Hall of Disjointed Memories album.
