Volunteers are the heartbeat of the Jefferson County Open Space system. In 2024, 6,038 individuals logged 57,000 working hours. They completed 549 projects, preserved 291 acres and created 17 miles of new trails.

All this effort represented the equivalent of 31 full-time workers, said Tom Hoby, executive director, at the 2025 Conservation Awards ceremony Jan. 30 at the Lakewood Cultural Center. 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.

Remembering the Founders – Carol Karlin

The Woman of the Living Room Legacy

By Vicky Gits and Bette Seeland

Karlin is credited with launching PLAN Jeffco and the open space movement in 1971 from her Lakewood living room along with a gathering of members of the League of Women Voters and others.

Without the vision and genius of Carol Karlin the Jefferson County Open Space system might never have become reality.

Thanks to Karlin’s idea of scooping up cheap acreage for posterity, the Front Range enjoys a generous portfolio of trails and parks owned and maintained in perpetuity by the residents of and visitors to Jefferson County who pay a half-cent sales tax.

This explains why there is a charming outdoor seating nook framed in pinon and boulders in a distant corner of Elk Meadow Park in Evergreen. Established sometime around 2008, the site is marked with the sign that says, “Carol Karlin Overlook.” Read more

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.

2024 Open Space Survey

It’s that time again, when — every few years — Jeffco Open Space elicits feedback from the public on issues like planning for the parks, and improving and maintaining not just the Open Space Parks, but also shared parks, trails and open spaces.  Here’s your chance to voice an opinion on our Jeffco Open Space Parks. The survey will be open for just a short time, so go to this page and start engaging!

ME, MY DOG & THE GREAT OUTDOORS

This is a repost of the article written in April 2021 by D. Jean Tate. Riley is no longer with us, but Jean and Leia, her new trekking companion, continue to visit the Parks. The information and lessons learned are as important today as they were in 2021. We hope you appreciate the reminder and enjoy the read.

Jean Tate and Riley at White Ranch OS Park

Sharing the outdoors with your dog—it’s one of the most enjoyable things I know!  For that reason—and because our open lands and trails are used by wildlife plus an ever-increasing number of people for a variety of activities, and also because of dogs’ natural inclinations—there are rules to be followed when you and your dog are outdoors, outside the bounds of your private property.  Those rules vary by location based on political boundaries, land ownership, and land management.

Miss Mountain Manners-PLAN Jeffco

Miss Mountain Manners wants to thank everyone who will take part in the 2024 SLASH program.  Removing slash and creating a defensible space around your home is the first line of defense against wildfires, which are a consistent cause for concern in Jefferson County. You can create zones around your home, removing any fire fuels, such as tree debris, to create a properly mitigated property. This doesn’t mean that wildfire will pass you by, but it gives the fire department a better opportunity to save your home when it does happen. Great tips on how to protect your home and property can be found on the Jeffco Sheriff’s hazard mitigation page and at FireWise website. Jeffco’s CSU Extension also has a  factsheet that can help homeowners plant low-flammability gardens.

Earth Day 2024 Fun at Crown Hill

Cathi, Michelle, Courtney at Crown Hill registration 2024-04-20

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-PLAN Jeffco

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.”
