 ‭(Hidden)‬ History

From Gravel Mine to Ecosystem

The eastern side of Pella Crossing was opened to the public in 1996 after it was donated to the county by Frontier Materials, Inc. in 1992. The property was an agricultural site before it was mined for gravel from 1975 to 1990.

In 1995 the western property was purchased from Willis and Alberta Marlatt and added to Pella Crossing.

The Name

This spot, called “Laramie Crossing” in 1860s, is where the Overland Trail stagecoach crossed the St. Vrain Creek en route from Denver to Laramie, Wyoming.

Hygiene Elementary 5th graders won a competition to name the donated open space property. They chose the name, Pella Crossing, because the property is the midpoint between 19th century towns Pella and North Pella.
