We arrived in Denver!
This shot is only part of a mural in the terminal.
Here's a the info I found:
Leo Tanguma's "In Peace and Harmony with Nature" references the social realist murals of Mexico while addressing a modern theme: the destruction of the environment. The first half of the mural shows children displaying great sadness over the destruction and extinction of life, as the second half of the artwork depicts humanity coming together to rehabilitate and celebrate nature.
