Polychrome Pass Part II

Polychrome Pass is located inside Alaska's Denali National Park. The National Park is home to Mount McKinley or Denali which, at a height of approximately 20,320 feet, is the highest mountain peak in North America. Mount McKinley is more commonly referred to by its Athabaskan name Denali, meaning "The Great One".

Because print in the photo is way too small to read I have printed it here:

About 60 million years ago the mountain on which you stand and those across the valley were part of a low plain composed of deep beds of gravel covered by ancient plains and varied animal life. The plain was uplifted and folded into mountains. Molten rock pushed into the gravel and some poured out onto the surface as lava.
As mountain-building forces continued to push the land skyward, rushing streams stripped the slopes of most of the original sands and gravels. Some were mixed and fused by the volcanic rocks. The multi-hued lavas intrusive rocks and cemented gravels give the mountain its brilliant colors and inspired in early travelers the descriptive name "Polychrome Pass".
