Original Thornton
By Jessica Carcoana · Updated September 2026
Original Thornton traces to the town's first plat, recorded with Adams County in February 1954, and its brick ranch houses went up mostly between 1956 and 1975 on lots running a quarter acre or larger, many without an HOA. Community Park, near East 88th Avenue, holds the Thornton City Pool, a skate park, and tennis courts, and Pelican Ponds Open Space runs along the neighborhood's east side with walking paths and fishing access. I-25 and I-76 are each about five minutes away. Mapleton Public Schools covers part of the area, with Adams 12's Thornton High School serving the rest. Prices here start in the high $300,000s, among the lowest in the city.
