Martha Ferguson has lived in Old Snowmass since 1984. One morning she woke before dawn, looked east from her bedroom, and found the sky erased. A neighbor had installed two exterior light columns that were blasting upward through the night, and the glare swallowed the entire eastern horizon.

That moment is where WildSky Old Snowmass began.

In February 2026, after years of community organizing, county-level lobbying, and a Pitkin County lighting ordinance that had been four years in the making, DarkSky International officially certified Old Snowmass as an International Dark Sky Community. It is the eighth such community in Colorado and the first in the Roaring Fork Valley. Old Snowmass is unincorporated ranch land with no formal municipal government. It earned this designation anyway.

That distinction matters. What the certification protects is not a policy abstraction. It is the specific quality of sky that drew most people to this valley in the first place, and it now has a legal framework defending it.

The Certification and the People Behind It

The effort was genuinely local. Ferguson founded WildSky Old Snowmass and spent years working alongside the Capitol Creek Caucus, the nonprofit neighborhood organization dedicated to the surrounding environment, to build the case for certification. She presented before Pitkin County commissioners, spoke at the Aspen Center for Environmental Studies, and brought her case to neighboring caucuses across the valley. The coalition she assembled was unusually broad: Aspen Valley Land Trust, Wilderness Workshop, Roaring Fork Audubon, the Aspen Skiing Company, and the Lowell Observatory in Flagstaff, Arizona all signed on as supporting partners.

Pitkin County Commissioner Jeffrey Woodruff, whose district includes Old Snowmass, framed the certification in terms that go well beyond stargazing:

"The valley of Snowmass and Capitol Creek are critical wildlife habitats. Maintaining the night sky protects this crucial land and complements the protections we have put in place through conservation easements and additions to wilderness."

DarkSky International's announcement traced Old Snowmass's history from Jurassic-era dinosaur habitat through Ute summer hunting grounds to the agricultural hub that rose during Aspen's silver boom in the 1880s. The community has remained largely undeveloped across all of it. The certification is, in one sense, a formal acknowledgment that Old Snowmass intends to stay that way.

What the Ordinance Actually Requires

Certification required real regulations, not just stated intentions. Pitkin County adopted an updated lighting code with a specialized overlay written specifically for Old Snowmass. The rules are concrete:

• Most exterior lights must be extinguished between 10 p.m. and 6 a.m.
• Exterior holiday lights are prohibited outside a defined seasonal window
• Fixture covers and bulb types are regulated to reduce sky glow and prevent glare
• Businesses operating during overnight hours, along with street and parking lot lights, are among the narrow exceptions

Ferguson has been consistent on this point: the code is not a prohibition on outdoor lighting. It is a design standard. Fixtures that direct light downward, bulbs calibrated for warmth rather than intensity, timers that cut lights after a reasonable evening hour: these are the tools. The sky glow that had been creeping toward the eastern horizon above the ranches does not reverse overnight, but the legal architecture to push it back now exists and is enforceable.

Why the Timing Was Not Accidental

The years following 2020 brought a surge of residential construction to the Roaring Fork Valley. The DarkSky International announcement noted it directly: new building had created a rise in construction activity and a corresponding threat of light pollution. Old Snowmass absorbed that pressure at a rate few communities its size did, because its combination of acreage, privacy, and proximity to Aspen made it exactly what a certain category of buyer was looking for.

Those buyers arrived with expectations calibrated to urban or suburban settings: floodlit driveways, uplighting on specimen trees, motion-sensor perimeters that fire at midnight. None of those choices are malicious. As Ferguson acknowledged to the Aspen Times, most non-compliance was unintentional. The ordinance addresses a pattern, not a person, and the community supported it by a wide margin.

DarkSky Colorado now lists Old Snowmass as a destination that "feels wonderfully untouched." That description carries a maintenance requirement. The community voted for it with years of meetings, commission testimony, and neighborly conversation at Buttercup Ranch and up and down Capitol Creek Road.

The Summer Sky, Specifically

For Old Snowmass residents, the practical shift becomes most visible between late June and early October. The Milky Way is positioned overhead on clear nights during those months, and at approximately 7,500 feet under an enforced dark sky ordinance, it is visible in a level of detail that about 75 percent of Americans can no longer see from where they live.

The access point most residents already know is the Capitol Creek Trail, which leaves from a trailhead at the end of Capitol Creek Road, roughly 14 miles west of Aspen on Highway 82. The trail runs 12.7 miles into the Maroon Bells-Snowmass Wilderness, gaining 3,116 feet to Capitol Lake, with the 14,115-foot Capitol Peak rising above it. From late July through September, the corridor is thick with wildflowers. Cattle share the lower stretches with hikers. Mountain goats appear near the lake. The trail sees enough horse traffic that the tread is well established and popular with equestrians as well.

For those who want the wilderness sky without the day hike home, Capitol Creek Outfitters runs overnight horseback pack trips into the area, which means falling asleep under a sky that, for much of the country, simply no longer exists. Before the pavement ends on Capitol Creek Road, the Old Snowmass Market and Liquor Store handles the supplies: burritos, coffee, snacks, and printed materials about the dark sky initiative that WildSky has placed there specifically for hikers and visitors heading up the canyon.

The Aspen Center for Environmental Studies has run guided night sky programming in connection with WildSky Old Snowmass. Dr. Jeffrey Hall, executive director of the Lowell Observatory, has spoken publicly in Old Snowmass about the effect of light pollution on active astronomical research. The Lowell Observatory remains an organizational partner in the effort.

One implication of the certification extends beyond the personal. Rural communities with controlled light pollution have documented growth in eco-tourism and a specific category of traveler who plans trips around dark sky designations. Old Snowmass is now on that map in a way it was not twelve months ago.

The character of a place is made up of choices, and this one was made deliberately, at the community level, over several years. That kind of agreement is unusual. It is also the reason Old Snowmass feels different from the ranches that simply happen to be near Aspen.
