In January’26, a blog post titled “Mountain Pine Beetle Infestation 2026” appeared in this blog.

Eight months later, sometime toward the end of summer, the Mountain Pine Beetles (MPBs) will have flown. They began their yearly exodus around the middle of June. A day or two after the beetles flew, the females began to burrow under the bark of pine trees – mostly Ponderosa and lodgepole pines in Jefferson County.

WINTER IN THE PARKS – HOW TO STAY SAFE

/0 Comments/in , , , , , /by

Even though it’s only September, there’s no time like the present to post this safety reminder for activity in the parks during the winter months, especially given the extraordinary climate pattern we’re experiencing with the 2026-2027 El Niño.

This article was originally penned back in 2015 by Shaun Howard, who was the Jeffco Open Space Ranger Lead at that time. She wrote this post in an effort to help all Open Space Park visitors understand a little more about how to enjoy winter activities in the Parks.  

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.

The Boettcher Mansion as seen from the Mule Deer garden.

By Victoria Gits, PLAN Jeffco Staff Writer and Board Secretary

Three years ago, the lovely, historic Boettcher Mansion on Lookout Mountain was surrounded by a mostly neglected landscape of overgrown grasses and weeds not really in keeping with the grand Arts and Crafts home known as a popular wedding venue.

Thanks to volunteer gardeners, today the grounds on three sides of the house are full of thriving annuals, perennials, shade-or-sun loving plants, flowering shrubs and vines. Even in mid-September one can peruse the zinnias, sunflowers, impatiens, daisies and mums – and petunias, calibrachoa, and sweet potato vine – lots and lots of them.

Instead of forgettable space, the outdoors is now a horticultural showcase and a destination worthy of taking visitors for a peaceful walk any time of day for free, with or without a wedding to attend. Read more

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

Alpine Sunflowers in the High Country - Centennial Cone OS Park

By Don Moore, PLAN Jeffco Board Member

An important tool in the toolbox to preserve open lands and natural landscapes is the use of conservation easements. Conservation easements have been increasingly gaining favor in recent years as a means to preserve wildlife habitat and agriculture lands, and to protect scenic views, lands for recreation, and lands of significant ecological, historic, or cultural value.

DEAR MISS MOUNTAIN MANNERS – An Advice Column on Multi-Use Trail Etiquette

/0 Comments/in , , , , , /by

In memory of our beloved Board member Bette Seeland, we’re republishing a few of the articles in which she was a major contributor…this is one of them.

Dear Miss Mountain Manners: When I got to my favorite Jeffco Open Space Park for a hike, the parking lot was full. What should I do? Feeling Shutout

Dear Shutout: You could walk close to home instead of driving to a park. Do not park on the road shoulder leading to the park. Download, sign up, then check the LotSpot parking lot app to find a park not currently overcrowded.  Come at a time when the park is less crowded such as weekdays, before 9 am or after 3 pm.

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.

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.
