About Coors Field
Opened in 1995 in downtown Denver, Colorado, as home of the Colorado Rockies, and the highest-elevation ballpark in the majors. A single row of purple seats in the upper deck marks exactly one mile above sea level.
A humidor was installed before the 2002 season to store baseballs in damper conditions and offset Denver's thin, dry air.
