Overview

Centennial Cone, the centerpiece of its namesake park, Centennial Cone Open Space, is a fine little Jefferson County Peak. With forested green north slopes and sun-baked south slopes, the mountain hosts diverse plants and grasses including Prickly Pear, Mountain Mahogany, Ponderosa Pine and Douglas Fir. The summit is rocky and windswept and affords delightful views of neighboring Jefferson County Eighters and Niners as well as big high country peaks to the west and southwest.

In late summer, ladybugs, which spent the summer in the plains gorging on aphids, make many lower (generally Eleveners and lower) Colorado summits home and Centennial Cone is one such summit. Breeding ladybugs will cover summit surfaces so thickly one cannot walk without crunching them. As summer turns to autumn then winter, the bugs huddle under rocks or leaf litter and wait out the cold weather in a state of dormancy called diapause, before returning to the plains in the spring.

The Centennial Cone area also delivers a rich history lesson. The nearby Travois trail was used by Arapaphoe Indians to pass from the mountains to the plains. Later, homesteaders ranched livestock on the grasses surrounding the peak. Ruins of an old mine can be found in a gully on the northwest slope of the peak. Jefferson County completed land purchases from multiple owners over several years to create the Open Space we have today. This Jefferson County PDF provides more detail on the history of the area.

Weather & Seasons

Centennial Cone from the WestThe Centennial Cone Summit Area
Summer: Summer will bring heat and crowds to this open space. This area is very sunny with little shade, so bring sunscreen and a brimmed hat. Winter through Spring: Check the status of area Elk Closures before venturing out to visit this peak. Also be forewarned that the narrow, steep, guardrail-free road to the western entrance could be treacherous in slick conditions. Fall: From late September through the beginning of Elk closures is probably the prime time to visit Centennial Cone. The days are cooler, the sun less fierce, the crowds thinning a bit. As a bonus, the high country to the west and southwest may already be cloaked in early season snow.
