ENOR Environmental Discovery Camp Has Scholarships

ENOR group hiking in the park

You’re hiking or cycling in one of our Open Space parks. You encounter a group of kids with a couple of adults, and they seem totally engrossed in a patch of shrubbery. You stop for a moment, you hear children’s voices exclaiming about what they’ve found – they seem so excited about everything around them.

Welcome to ENOR – Eagle’s Nest, Owl’s Roost – Environmental Discovery Camp, which is sponsored by the Jeffco CSU Extension office. ENOR has been in the business of getting kids outdoors for more than 50 years.

Jeffco Parks & Open Space was so impressed with ENOR’s achievements that, in 2024, they presented ENOR with the Gambel Oak Award, as a Pioneer in Environmental Education, at that year’s Conservation Awards Ceremony. Read more

The map at the entrance to the refurbished and new trails in the former Bark Park in Evergreen.

After being closed for restoration since 2017, the former dog park and trailhead off Stagecoach Boulevard reopened Oct. 25, 2025, as a feature inside Elk Meadow Park in Evergreen. Dogs are still welcome in the park, as they are elsewhere in the system, but they must be on leash, as there is no fenced, off-leash area.

The Stagecoach Trailhead is about two miles west of Evergreen Parkway on the south end of Elk Meadow Park. The enclave has 107 acres compared to 1,600 acres in the whole of Elk Meadow Park. Read more

UPDATE 11/20/2025: The trailhead formerly known as the “as yet to be named trailhead” now has a name. The CCR (Colorado Central Railroad) Trailhead was the site of a grand opening ceremony for the eastern 1.25 miles of the Huntsman Segment on this day.

An engineering miracle on Jeffco Parks & Open Space land is nearing completion in Clear Creek Canyon along U.S. 6. Just beyond Tunnel One, the new segment of the Peaks to Plains Trail is expected to partially open before the end of 2025.  This is a moment that Open Space has been planning for years.

Currently under construction is a 3-mile concrete trail deep inside one of the least forgiving passages along the rugged river’s granite gorge. Read more

Take Notice — Winter Is Here!

A few years ago, Shaun Howard, who was the Jeffco Open Space Ranger lead at that time, wrote this post to help all Open Space Park visitors understand a little more about how to enjoy winter activities in the Parks. It’s time to republish as a reminder.

Our parks are “primitive” parks. Don’t expect the trails to be groomed for you. Make sure you have micro-spikes with you, just in case you need them. Be prepared for any type of weather, especially as you gain in elevation. Know before you go.

Temps have dropped and winter winds lick the landscape of the Jeffco Parks. Although the winter season has arrived, the parks are still great places to visit. Read on for essential winter safety tips.

Trails Through Time: A Geologist’s Guide to Jefferson County Open Space Parks

Typical outcrop of 1.4 billion year old granite in Alderfer/Three Sisters Park.

Typical outcrop of 1.4 billion year old granite in Alderfer/Three Sisters Park.

This article was initially published in 2014. Between then and now, the link to the full document was lost. Thankfully, we’ve just been able to recover a copy of the document, thanks to generous efforts by the USGS. We’ve embedded the document in our own library, for safekeeping. This repost will lead you to the full story of the geologic history of Jeffco’s Open Space Parks, as they were in 2014.

Jefferson County straddles one of the most conspicuous and important geographic and geologic boundaries in western North America, the eastern flank of the Rocky Mountains. To the east you can travel 1,100 miles across Great Plains and Central Lowlands before you sight the western foothills of the Appalachians. If you travel in the other direction you will cross or skirt mountain range after mountain range until you sight the Coast Range near San Francisco, more than 900 miles to the west. Many of these mountains have different ages and origins than the Colorado mountains, but they are all part of the great mountain belt called the North American Cordillera that extends along the western edge of the continent from Alaska through Mexico.

HISTORICAL versus CONTEMPORARY WILDFIRES

Wildfires in the mountain west have become less frequent but more intense.

Recently, the Denver Gazette published a short article on current research comparing historical versus contemporary wildfires in the America Southwest, with (to this reader) some rather surprising results.

The areas investigated in this study were primarily dry conifer forests dominated by Ponderosa pine and Douglas fir, very similar to our own forests in the Jeffco Front Range. Prior to 1880, wildfires used to sweep through these forests every 10 to 12 years. These were almost entirely low-to-moderate intensity fires that cleared out undergrowth and forest duff, burning off the lower limbs of the trees, but not devastating enough to kill the trees themselves. Typically, these low-intensity burns involved smaller areas, 5 to 250 acres. Despite the small size of these wildfires, the frequency and style of these fires were able to maintain forest health, even during prolonged periods of drought, when fires were started by lightning strikes and/or Indigenous forest stewardship events.

The Invasives – Poison Hemlock & Cow Parsley

Poison Hemlock thumbnailIt’s time for a change of pace. Today we’re going to talk about two invasive plants that look so similar but which have drastically different consequences. Both can be found in our Open Space parks.

Poison Hemlock v. Cow Parsley — can you tell the difference?  Here’s an article written for Foothills Living Magazine; we’ve been given permission to post as a public service.

Poison Hemlock_Cow Parsley_Aug24 18

Why be concerned about this, or any other invasive plant? They’re called invasives because they’ve moved into an ecosystem within which they did not evolve, usually with help from human activity. When this happens, when an invasive finds a new environment within which it can thrive, it’s usually without the lifestyle controls with which it evolved. Without these restraints, the invasive not only thrives, it takes over and overwhelms indigenous plants, sometimes to extinction. The plant-eating critters that evolved with the indigenous plants may not be able to tolerate the invasives, and they, too, fail to thrive. The carnivores who feed on the plant-eaters begin to fail…and so it goes, like a stack of dominoes. That’s why invasives — the plants — need to be controlled and in the worst cases, eliminated.

For more information from Jeffco Open Space on invasive plant species, go to https://www.jeffco.us/2007/Noxious-Weed-Identification

So when you’re trekking in the Jeffco Open Space Parks, keep your eyes peeled for these lovely but, in some cases, deadly invasives — and don’t touch!

Earth Day 2024 Fun at Crown Hill

Your PLAN Jeffco Board members (left to right) Cathi Schramm, Michelle Poolet, and Courtney App, get ready to head out into Crown Hill Park to plant trees and shrubs.

What were you doing on the Saturday before Earth Day, 2024?  Three of your PLAN Jeffco Board members joined 124 other Jeffco Open Space volunteers to plant more than 350 (some say as many as 600?) native trees, shrubs and forbs (grass plugs) at Crown Hill Open Space Park, along with multiple patches of native wildflowers.

Crown Hill on Earth Day 2024-04-20

The day was dark and gloomy, but the planting crew trudged on through the snow and mud…

Despite the cold and snow, 127 conservation enthusiasts weathered the chilly temperatures, including 50  Columbine High School students.  Traipsing through the snow and mud, lead by JCOS Natural Resource and Trails staffers, we got the job done before the snowfall resumed in the early afternoon.

One more Rocky Mountain Glow maple tree planted — hurray!

Initial success was measured by the feeling of accomplishment as a tree – in this case, a Rocky Mountain Glow maple – went into the ground. With luck and average annual rainfall (the trees on the east end of the park will not get any supplimental water), this maple will grow 20 to 30 feet tall, and will bear reddish-gold leaves in the fall. The chokecherry, wax current, rabbit brush and potentilla will grace the park with their flowers and fruit, while providing food and shelter for the smaller native inhabitants of the park.

The morning’s wet and cold and muddy activities wound up with a hot lunch buffet, catered by Illegal Pete’s and served by staffers from the JCOS Communications Team. The food was delicious – roasted meats, rice and beans, and Pete’s famous fajita and primavera veggies were top of the line, with plenty to go around.  To top off the meal, the chocolate chip cookies were baked to the chewy stage, so good that they begged you to have another one.

It might be safe to say that, despite the inclement conditions, everyone at the Earth Day event had a good time.

Our thanks to JCOS and the Natural Resource, Trails and Communications teams for organizing and executing this 2024 Earth Day activity, and for upholding the meaning and intent of Earth Day.

From National Geographic Education encyclopedia: “Earth Day is an annual celebration that honors the achievements of the environmental movement and raises awareness of the need to protect Earth’s natural resources for future generations. Earth Day is celebrated on April 22 in the United States and on either April 22 or the day the spring equinox occurs throughout the rest of the world.”

Miss Mountain Manners says: “This coming summer, when you’re strolling around Crown Hill Open Space park, look for native wildflowers on the north side, along 32nd Avenue, across from Wheat Ridge High School — but don’t pick the flowers! In the fall, as you walk the trails on the southeast side of the park, please stop and admire the red-gold leaves of the young maple trees and the brushy golden flowers of the rabbitbrush. Be proud of being a part of Jeffco Open Space.”

A Volunteer Park Patroller’s Perspective

What’s it like to be a Volunteer Park Patroller with Jeffco Open Space?

With over two dozen parks, more than 270 miles of trails and nearly 60,000 acres in the system, a Volunteer Park Patroller has many options. Once you’ve been vetted and trained as a Park Patroller, you can sign up for a specific date and time at a park of your choice, but there’s no rule that says you can’t spontaneously “stop by” a park on the way home from work. It’s unlikely you’ll see another Volunteer Patroller, except perhaps on a busy summer weekend, but if you do, there are plenty of other alternative parks to visit for a patrol, none of them very far away.

The range of park experiences is huge. Read more

Empty pillar where interpretive sign once stood.

Founders Sign Removed from Open Space Park

Empty pillar where interpretive sign once stood.By Vicky Gits and Bette Seeland, Nov 26, 2023

Early this year Jefferson County Open Space quietly removed without replacing an interpretive sign that had stood for about 20 years as a tribute to the visionaries whose genius and hard work launched PLAN Jeffco and created the Open Space Park system.

Now that the sign is gone, it is probably gone for good, according to Matt Robbins of the Open Space department.  Positioned in Elk Meadow Open Space in Evergreen, the sign was removed because it had fallen into disrepair after weathering outdoors for so long.

Evergreen resident Joe Mackey brought the missing sign to the attention of the Open Space Advisory Commission in October at a regular meeting. A former member of OSAC in the ‘70s, Mackey thinks the sign should be preserved. Read more
