Located next to Rocky Mountain Elementary School, Rothrock Dell Park was named in 1973, to commemorate two early families joined by marriage. William H. Rothrock (1867-1955), was born at his father's ranch on Boulder Creek and grew up to be a famous horseman. He managed the horse herd and then the entire ranch until 1926 when he retired to Longmont.

Rothrock's father, John, had joined gold seekers traveling west in 1858, but he found he could make far more money farming and selling potatoes than mining. He built the first log cabin in Boulder County. In 1893, William married Clara Agnes Dell (1873-1975), daughter of George T. Dell, owner of the valley's first hardware store at 324 Main St., who had come to Longmont in 1871. Rothrock Dell Park is a 6.4 acre park and was developed from 1977 to 1979, bordering the Oligarchy Greenway.

Many schoolchildren and neighbors enjoy the park's ball field, sports courts and playground. To view a complete list of park amenities and associated trail distances, visit our Plans, Maps & Reports webpage and view the Park Amenities Chart.
