## History

[edit]

The Alamosa, Colorado, post office opened on March 12, 1878,[12] and the Town of Alamosa was incorporated on August 12, 1878.[4] The town was established by the Denver and Rio Grande Railroad and quickly became an important rail center.[13] Alamosa was the terminus of the D&RG until 1881, when the line was extended to Monte Vista.[14] The railroad had an extensive construction, repair, and shipping facility in Alamosa for many years and headquartered its remaining narrow gauge service here with trackage reaching many points throughout southwest Colorado and northern New Mexico. Alamosa County was created on March 8, 1913, with Alamosa as its first and only seat.

Alamosa is now a notable tourist town with many nearby attractions, including the Great Sand Dunes National Park and Preserve, Colorado Gators Reptile Park, and the Rio Grande Scenic Railroad. The town hosts "Summer Fest on the Rio" which occurs the first weekend in June, the Early Iron car show over the Labor Day weekend, and "Weekends on the Rio" on various Sundays throughout the summer[15] The city takes its name from the Spanish adjective Alamosa, meaning "of cottonwood", for the cottonwood forests which grow along the Rio Grande and throughout town.[5]

## Geography

[edit]

Alamosa is located at the junction of U.S. Routes 160 and 285. At the 2020 United States Census, the city had a total area of 4,910 acres (19.871 km2) including 47 acres (0.192 km2) of water.[11]

Alamosa is located along the Rio Grande in the San Luis Valley, in the highest general agricultural land in the United States. Elevation is about 7,544 feet (2,299 m) in Alamosa with peaks over 14,000 feet (4,300 m) within 23 miles (37 km) of town in the Sangre de Cristo Range.

Alamosa is the gateway city to the Great Sand Dunes National Park and Preserve.

There was a long-term annual average of 227 days per year with a minimum of 32 °F (0 °C) or less.[16] In the 1981–2010 period, there was an average of 46 nights with minima at or below 0 °F (−18 °C).
