The Colorado Portal

Colorado is the state of the United States of America that encompasses most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the high western edge of the Great Plains. Admitted to the Union on August 1, 1876, Colorado became the 38th U.S. state. Colorado ranks 21st in population, eighth in total area, and first in mean elevation among the 50 U.S. states. Fifty-five of the 124 highest major mountain peaks of North America rise in Colorado. The United States Census Bureau estimated that the population of the State of Colorado was 5,829,926 on July 1, 2022, an increase of 1.15% since the 2020 United States census. Denver is the state capital, the most populous city, and the heart of the most populous metropolitan area of the Rocky Mountain Region. Colorado Springs is the state's second most populous city. While the population of the Front Range Urban Corridor now exceeds five million, many rugged portions of the state remain pristine wilderness.

Interstate 70 (I-70) is a transcontinental Interstate Highway in the United States, stretching from Cove Fort, Utah, to Baltimore, Maryland. In Colorado, the highway traverses an east–west route across the center of the state. In western Colorado, the highway connects the metropolitan areas of Grand Junction and Denver via a route through the Rocky Mountains. In eastern Colorado, the highway crosses the Great Plains, connecting Denver with metropolitan areas in Kansas and Missouri. Bicycles and other non-motorized vehicles, normally prohibited on Interstate Highways, are allowed on those stretches of I-70 in the Rockies where no other through route exists.

The United States Department of Transportation (USDOT) lists the construction of I-70 among the engineering marvels undertaken in the Interstate Highway System and cites four major accomplishments: the section through the Dakota Hogback, Eisenhower Tunnel, Vail Pass, and Glenwood Canyon. The Eisenhower Tunnel, with a maximum elevation of 11,158 feet (3,401 m) and length of 1.7 miles (2.7 km), is the longest mountain tunnel and highest point along the Interstate Highway System. The portion through Glenwood Canyon was completed on October 14, 1992. This was one of the final pieces of the Interstate Highway System to open to traffic and is one of the most expensive rural highways per mile built in the country. The Colorado Department of Transportation (CDOT) earned the 1993 Outstanding Civil Engineering Achievement Award from the American Society of Civil Engineers for the completion of I-70 through the canyon.

Clara Brown
Clara Brown
Clara Brown (1800–1885) was a former enslaved woman from Virginia and Kentucky who became a community leader and philanthropist. She helped formerly enslaved people become settled during Colorado's Gold Rush. She was known as the 'Angel of the Rockies' and made her mark as "Colorado's first black settler and a prosperous entrepreneur".

Brown, born in Virginia in 1800, moved to Logan County, Kentucky, with her family. She married another enslaved person when she was 18 and they had four children. In 1835, Brown's family was broken apart when they were all sold to different slave owners. When Brown was 56, she received her freedom but was required by law to leave the state. She worked her way to Denver, Colorado as a cook and laundress on a wagon train.

Brown settled in the mining town now called Central City, Colorado where she worked as a laundress, cook, and midwife. With the money she made, she invested in properties and mines in nearby towns. Known as "Aunt Clara" for her emotional and financial support, Brown was a founding member of a Sunday school that was held in her home. (Full article...)

State Highway 74 (SH 74) is a state highway in the U.S. state of Colorado. Running 18 miles (29 km) from Interstate 70 (I-70) in El Rancho to SH 8 in Morrison, the highway roughly follows a hook-shaped path running northwest–southeast. The section of the route north of the town of Evergreen is known as Evergreen Parkway and is a segment with a four- to six-lane roadway, with the section east of Evergreen mostly two lanes. The other section is known as the Bear Creek Canyon Scenic Mountain Drive, or just Bear Creek Road, and primarily parallels Bear Creek, passing through the towns of Kittredge and Idledale. The route, which is on the outskirts of Denver, passes through several of the city's mountain parks, including Bergen, Dedisse and Red Rocks parks.

An early road following the current path was established in the late 19th century for miners and loggers. As floods ravaged the road along Bear Creek through the early 20th century, measures were taken to prevent further damage. Other sites along Bear Creek, such as a Civilian Conservation Corps (CCC) camp in Red Rocks Park and the Bear Creek Canyon Scenic Mountain Drive, as the section between Idledale and Morrison is called, have given the route a listing on the National Register of Historic Places. An early designation of the route number went further west than its current-day designation; that section was truncated by the late 1930s. Another eastern segment was added from Morrison east toward Denver in the 1940s, but that section too was removed. Newer improvements to the road include widening the Evergreen Parkway segment to four lanes and constructing an interchange with I-70. (Full article...)
