“Beulah red” is the name of the red marble that gives the Colorado State Capitol its distinctive splendor. Cutting, polishing, and installing the marble in the Capitol took six years, from 1894 to 1900. All of the “Beulah red” marble in the world went into the Capitol. It cannot be replaced, at any price. The 13th step of the state capital building in Denver is exactly 1 mile high above sea level.
