This is a list of National Natural Landmarks in the U.S. state of Colorado.
There are 16 National Natural Landmarks in Colorado, one of which extends into Wyoming. They cover areas of geological, biological and historical importance, and include lakes, mountains, rock formations and numerous fossil sites. The landmarks are located in 14 of the state's 64 counties. Four counties each contain all or part of two NNLs, while two landmarks are split between two counties. The first two designations, Slumgullion Earthflow and Summit Lake, were made in 1965, while the most recent designation, Sulphur Cave and Spring, was made in 2021. Natural Landmarks in Colorado range from 60 to 380,000 acres (24.3 to 153,780.5 ha; 0.1 to 593.8 sq mi) in size. Owners include private individuals and several municipal, state and federal agencies.

Selected biography -
Zebulon Montgomery Pike
Pike's second expedition crossed the Rocky Mountains into what is now southern Colorado, which led to his capture by the Spanish colonial authorities near Santa Fe, who sent Pike and his men to Chihuahua (present-day Mexico) for interrogation. Later in 1807, Pike and some of his men were escorted by the Spanish through Texas and released near American territory in Louisiana.
In 1810, Pike published an account of his expeditions, a book so popular that it was translated into several languages for publication in Europe. He later achieved the rank of brigadier general in the American Army and served during the War of 1812 until he was killed during the Battle of York in April 1813, outside the British colonial capital of Upper Canada.

The Platte Canyon High School hostage crisis was a hostage taking and shooting at Platte Canyon High School in Bailey, Colorado, on September 27, 2006. The gunman, 53-year-old Duane Roger Morrison, took seven female students hostage and sexually assaulted them, later releasing four. When police broke open the classroom's door with explosives, Morrison opened fire with a semi-automatic pistol before shooting hostage Emily Keyes in the head. The other remaining hostages escaped unharmed, and paramedics confirmed that Morrison had committed suicide shortly before police were able to enter the classroom. Keyes was pronounced dead at 4:32 p.m. MDT (23:32 UTC) at Saint Anthony's Hospital in Denver, Colorado, after undergoing emergency surgery. (Full article...)
