Bradford House II (Site 5JF51) is a prehistoric rockshelter, 24 kilometres (15 mi) southwest of Denver. It is situated on land owned by the Ken-Caryl Ranch Master Association. It was excavated in the summer and fall of 1973 by the Denver Chapter of the Colorado Archaeological Society. The excavations found several cultural features and recovered thousands of chipped stone artifacts, dozens of ground stone artifacts, a few ceramic sherds, bone tools, and faunal remains. The site was used by prehistoric groups during the Middle and Late Archaic periods, as well as the Early Woodland, and Middle Woodland periods. This is a span of 4,500 years. Bradford House II is located in the Ken-Caryl Valley. The Front Range foothills to the west and the Lyons and Dakota hogbacks to the east frame the valley. An abundance of archaeological sites, attests to the valley's attraction for the earliest inhabitants of the area. They frequented the area for its abundant resources, including shelter under the many bedrock monoliths scattered across the valley, lithic materials for chipped stone tools, and edible plants and animals. West of the valley, the arkosic sandstones of the Pennsylvanian Fountain formation lie unconformably upon uplifted Precambrian metamorphic rocks of the Front Range (Rathbun 1997:21) . Although mostly covered by recent to pre-Wisconsin alluvium, the Fountain formation forms southwest facing escarpments, or monoliths, with undercut shelters or caves (Rathbun 1997:21), many of which were inhabited by prehistoric peoples. The elevation of the site is approximately 1878 m (6160 ft.) above mean sea level. Elevations surrounding the site range from about 1828 m (6000 ft.) in the Dutch Creek water gap to 1992 m (6536 ft.) on the highest point of the Dakota hogback ridge. The valley has a sunny, mild, and semiarid climate that has neither the extreme cold of the higher elevations to the west nor the hot summer afternoons of the eastern plains (Tate 1997:15). A south-facing rock shelter like Bradford House II absorbs a great deal of solar radiation, further mitigating the winter cold. Precipitation is moderate, averaging 15 to 18 inches, and winter snows melt quickly (Tate 1997:17) with frequent down slope (chinook) winds. The valley consists of various grasses and forbs. The surrounding hogbacks and foothills support a pine-Douglas fir vegetation community. The recovery of floral materials from Bradford House II and other archaeological sites in the valley (Johnson 1997:Table Gl) indicates that local plants such as sunflower, wild plum, acorn, and chokecherry were gathered and used by prehistoric peoples. Many animals, including elk, mule deer, and occasional Big Horn sheep, as well as a variety of carnivores, rabbits, rodents, birds, amphibians, reptiles, and fish are found in the hogbacks and foothills. Unworked animal, mostly mammal, bone was found in abundance in the Archaic and Early Ceramic levels (Johnson and Lyons 1997a:49, Table 6). Mule deer dominates the assemblage, followed by elk, bison, and rabbit, with little change in dietary preferences from the earlier to later time periods. Several bone tools (awls, beads, reamers, bone scrapers, and bone drills) and antler flakers were recovered from all cultural levels in the site (Johnson and Lyons 1997a) .

David S. D'Evelyn Junior/Senior High School (known as D'Evelyn) is a public secondary school near Lakewood, Colorado, United States. It is included in the Jefferson County R-1 public school district. While remaining an open public school without charter or magnet status, D'Evelyn consistently ranks among the top 100 high schools in the US. D’Evelyn’s academic tenets derive from the efforts of a volunteer council to create an "alternative educational environment" in the early 1990s. D’Evelyn’s eponymous founder, David S. D’Evelyn, died in a plane crash before the council's efforts resulted in the successful enactment of the Colorado Charter Schools Act of 1993 and the nascent school secured the "option school" status required to pursue its own academic objectives with a high degree of freedom from the district.

The Columbine High School massacre, commonly referred to as Columbine, was a school shooting and attempted bombing that occurred on April 20, 1999, at Columbine High School in Columbine, Colorado, United States. The perpetrators, twelfth-grade students Eric Harris and Dylan Klebold, murdered twelve students and one teacher. Ten of the twelve students killed were in the school library, where Harris and Klebold subsequently committed suicide. Twenty-one additional people were injured by gunshots, and gunfire was also exchanged with the police. Another three people were injured trying to escape. The Columbine massacre was the deadliest mass shooting at a K-12 school in U.S. history, until it was surpassed by the Sandy Hook Elementary School shooting in December 2012, and later the Robb Elementary School shooting in May 2022, and the deadliest mass shooting at a high school in U.S. history until the Parkland high school shooting in February 2018. Columbine still remains both the deadliest mass shooting and the deadliest school shooting to occur in the U.S. state of Colorado. Harris and Klebold, who planned for at least a year and hoped to have a large number of victims, intended for the attack to primarily be a bombing and only secondarily a shooting. But when several homemade bombs they planted in the school failed to detonate, the pair launched a shooting attack. Their motive remains inconclusive. The police were slow to enter the school and were heavily criticized for not intervening during the shooting. The incident resulted in the introduction of the immediate action rapid deployment (IARD) tactic, which is used in active-shooter situations, and an increased emphasis on school security with zero-tolerance policies. Debates and moral panic were sparked over American gun culture and gun control laws, high school cliques, subcultures (e.g. goths), outcasts, and school bullying, as well as teenage use of pharmaceutical antidepressants, the Internet, and violence in video games and movies. Many makeshift memorials were created after the massacre, including ones employing victims Rachel Scott's car and John Tomlin's truck. Fifteen crosses for the victims and the shooters were erected on top of a hill in Clement Park. The crosses for Harris and Klebold were later removed following controversy. Planning for a permanent memorial began in June 1999, and the resulting Columbine Memorial opened to the public in September 2007. The shooting has inspired dozens of copycat killings, dubbed the Columbine effect, including many deadlier shootings across the world. The word "Columbine" has become a byword for school shootings.
