Nestled between two immense sandstone monoliths, Red Rocks Amphitheatre is an acoustically perfect venue for concerts of all kinds. It seats over 9,000 people, has sponsored entertainment since its completion in 1936, and rises high enough that the Denver skyline can easily be seen.
Acoustics aside, the area is an impressive geological wonder, so much so that at one time, the amphitheater was considered one of the seven wonders of the world. The surrounding rocks were formed during the Pennsylvanian epoch almost 300mya, but formed their spectacular tilt when the ancient Rocky Mountains were formed, during a phenomenon called the Laramide orogeny. Embedded in these rocks are ancient dinosaur fossils that are studied to this day by paleontologists.
