In Stars Above, Earth Below, Tyler Nordgren examines a range of astronomical topic and makes the connection between them and the landscapes, processes, and cultures which can be seen and experienced within specific U.S national parks. for each park and topic the story unfolds in three steps: what does the reader see for him- or herself? What is the scientific cause or explanation of what is seen? And finally, what is the big picture about ourselves, our world, and our Universe? The author takes us the length and breadth of the United States, from the coast of Maine to the Yellowstone volcano, from the depths of the Grand Canyon to the heights of the Rocky Mountains, exploring the natural links between the features of the parks and those of our Universe.
