North Middle Fork Ranch

$2,250,000 Lyons, CO 600± Deeded Acres

Executive Summary

North Middle Fork Ranch (NMFR), 45 minutes outside Boulder between Lyons and Rocky Mountain National Park, is 600± acres of private, pristine and beautiful mountain land within the Roosevelt National Forest. Just off the dramatic South St. Vrain Canyon, NMFR lies at the end of a Forest Service Road and features undulating lush meadows, ponderosa and aspen forests, significant rock formations, and more than two miles of Dry St. Vrain Creek.

NMFR possesses unusual Boulder County-granted entitlements to construct sizable residential and recreational buildings. The owner may select any two of four outstanding surveyed building envelopes for improvements. On one site, a private residence and related buildings totaling 15,000 square feet are allowed; on the second site, the owner may construct up to 35,000 square feet of equestrian, agricultural and other buildings, including a 2,000-square-foot caretaker’s residence. A total of 50,000 square feet of buildings may be built.

In the context of Boulder County’s typically tight restrictions on any new homes in the mountains, these vested rights are extremely valuable. North Middle Fork Ranch represents a rare chance to construct - with minimized risks and constraints - a high-end residential-recreational compound that is both remote and within commuting distance from Boulder.

General Description

North Middle Fork Ranch is principally bounded by national forest lands; two other private parcels adjoin the property’s northerly and southeasterly boundaries. The entrance to the ranch is a gently rolling complex of healthy meadows and forests extending to the southerly rim of Dry St. Vrain Creek, which runs generally west to east for more than two miles through the property. Many springs, seeps and secondary drainages flow through the property into the seasonal Dry St. Vrain, which in turn joins North St. Vrain Creek, once a candidate for Wild and Scenic River status. Numerous aspen stands throughout North Middle Fork Ranch evidence the lushness of the ground. The northwesterly portion of NMFR, near the base of Big John Mountain within the national forest, contains an exceptional identified example of a native Foothills Ponderosa Pine Savanna plant community, exemplifying the generally premier quality of NMFR as a natural landscape. That corner of the property is an oasis of tranquil aspen groves and meadows frequented by elk and other wildlife. The easterly north-south edge of the ranch traverses a series of high rock outcrops and the westerly shore of Egg Lake, a national forest feature tucked behind an outcrop with a sandy beach perfect for an end-of-ride lunch or a long afternoon read. The lake, private in feel, is a destination that’s a significant trek for anyone but the NMFR owner. It’s not uncommon to encounter elk, bear, and the occasional moose among the many wild residents of North Middle Fork Ranch. 

Ranch History and Vested Development Rights
North Middle Fork Ranch was for generations the summer unit of the historic Hall Ranch, situated within the lush grazing lands of the surrounding Roosevelt National Forest. The lower Hall Ranch headquarters, between NMFR and Lyons, is now one of Boulder County’s premier Open Space destinations for hiking, mountain biking, spectacular red rock formations, and Longs Peak and Continental Divide panoramas.
Boulder County once sought to acquire NMFR to preserve its exceptional natural areas, native plant communities, and integral role in the surrounding national forest landscape and habitat. Unwilling to sell at that time, the current owners negotiated a mutually advantageous deal with the County. The County purchased a conservation easement interest that protects the land’s outstanding natural and scenic values, as well as continued established private agriculture, riding, hunting and recreation uses. As part of that transaction, the owner negotiated enhanced and simplified development rights, and a resulting streamlined land use process, attaching permanently to the ranch.

Through a county “Subdivision Exemption” process completed simultaneously with and as part of the conservation easement sale, the owner acquired vested property rights to select for development two of four prime building envelopes created on North Middle Fork Ranch. On one selected lot, the owner may construct a private residence and related buildings totaling 15,000 square feet; on the second selected lot, the owner may construct equestrian, agricultural and other related buildings, including a caretaker’s residence of up to 2,000 square feet, totaling 35,000 square feet. Within the larger conservation area outside the four generous building envelopes, the owner may construct up to 1,000 square feet of loafing sheds, plus corrals, pasture fencing and horseback riding obstacles, and develop through riding a complex of trails, all to accommodate the permitted equestrian, agricultural and recreational uses of the ranch. The four available development lots created under the Subdivision Exemption provide the owner choice and great flexibility for locating future improvements. It is important to note that all such lots, and the entire North Middle Fork Ranch, must remain under single ownership.

The County also approved the use of existing Forest Road 186, from Spruce Drive off South St. Vrain Drive (Colorado Highway 7), for residential and related access to North Middle Fork Ranch. To secure legal access to the property over the national forest, and the right to improve the Forest Road to County driveway standards as required for the permitted NMFR improvements, the landowner obtained a Forest Road Easement from the U.S. Forest Service.

Because these comprehensive development rights are vested and granted by the County as part of the consideration for the landowner’s preserving some of the most exceptional natural features of North Middle Fork Ranch under a conservation easement, the County’s future  discretion under its land use approval processes when building applications are submitted is quite limited.

With its completed land planning,  extensive vested development rights, and legal access over the national forest, North Middle Fork Ranch presents a unique private development opportunity in the mountains of Boulder County. With minimized time and risk to obtain required approvals and building permits, a purchaser can quickly begin realizing the property’s exceptional residential and recreational potential.

Conservation Easement & Vested Development Rights
For many ranch buyers, the presence of a conservation easement raises questions and concerns. All other things being equal, the natural preference is to acquire land with the fewest potential restrictions on its future use and development. The North Middle Fork Ranch landowner took steps to change this calculation. 

It is important to emphasize the context in which the NMFR conservation easement was granted by the landowner to Boulder County. The easement was sold as part of a heavily negotiated transaction with the County that created substantial value and flexibility for the owner. The County had sought to acquire full ownership of NMFR, but the ranch was not for sale at that time. While the property was then used solely for horseback riding, hunting, hiking and other outdoor recreation, the owner understood that the land’s ultimate highest and best use – its greatest economic value – lay in the opportunity to develop a significant private high-end residential and recreational compound for one family. The owner, therefore, took advantage of the County‘s keen desire to keep NMFR intact and the bulk of the 600± acres largely in their historic condition: a conservation easement interest was sold to Boulder County for a combination of cash and enhanced rights to maximize the ranch’s private value, with minimized County discretion or control over the end product.

Boulder County is a notoriously difficult place in which to build, particularly when it comes to new homes in the mountains. The County’s typical enforcement of onerous, expensive and time-consuming land use processes on mountain properties often frustrates landowners’ goals to build what they want, where they want. Many otherwise attractive homesites in the mountains of Boulder County have been rendered practically uneconomical to develop by the County’s restrictive exercise of its regulatory powers. 

The significance of the permanently vested development rights negotiated simultaneously with and as part of the conservation easement sale to Boulder County cannot be overemphasized. These vested rights allow a future owner to plan, design, permit and build, expeditiously, what otherwise would have been virtually impossible to achieve in this location.

Rather than a burden on the landowner’s opportunity to develop and use the property as desired – the usual knock on conservation easements – the net result of Boulder County’s acquisition of a conservation easement interest in NMFR was the landowner’s right to build far more significant improvements, in some of the choicest locations on the property, and to convert what would otherwise be a typically difficult County approval and permit issuance exercise into a comparatively simple and streamlined affair.

In short, the County’s desire to acquire a conservation easement over North Middle Fork Ranch created an opportunity to gain freedom for the landowner that far outweighs the restrictions associated with the conservation easement. The highest and best, most valuable private use of the property is what the conservation easement also contemplates and allows. “Unique“ is an overly-used term, but is particularly applicable to North Middle Fork Ranch: Build the home and improvements of your choosing, essentially what and where you desire on your selection of two of four choice, generous, surveyed sites, within a private, large and lush mountain landscape in Boulder County just 45 minutes from downtown Boulder. That’s unique.

Broker's Comments

North Middle Fork Ranch is, quite simply, a unique property given its size, variety, location and development entitlements. There are 600± end-of-the-road acres within the National Forest just 45 minutes from Boulder. Vested rights to build 50,000 square feet of buildings, including a main home up to 15,000 square feet plus a “caretaker’s residence” up to 2,000 square feet, anywhere within two owner-selected building envelopes on the four choice, negotiated, and surveyed sites ranging from around 5 to 8.5 acres each.

If you want to build a truly sizable home in the mountains of Boulder County, but away from it all, this is probably your best (and perhaps only) chance.  Or, if all you’re looking for is to build a cabin or smaller getaway home, you can create and enjoy the “caretaker’s residence” and hold the permanently vested rights to construct the larger improvements as a long-term investment or exit strategy.

Like other prime, beautiful and desirable, fast-growing and high-value locations in Colorado, Boulder County seems to get more restrictive with each passing year. A property of NMFR’s size, quality, location, and attached vested development rights will become more and more rare as time goes by.

North Middle Fork Ranch’s proximity to Boulder and the entire Front Range Corridor, as well as to Estes Park, Rocky Mountain National Park, and neighboring wilderness areas, provides exceptional convenience. Just inside the NMFR gate is a serene and wild landscape where time seems to slow, but the property is close enough to everything to be enjoyed on weekends, just for the day, or even for an evening picnic after work in town. The property lies at the end of the mile-long United States Forest Road 186, which begins on Spruce Drive (maintained by the Conifer Hill Road Association, of which the NMFR owner is a member) just a half mile off State Highway 7, one of the principal routes to Rocky Mountain National Park. The town of Lyons, with its shops, cafes and renowned bluegrass festivals, is just over 12 miles away; from there, Boulder is another 13 miles south via US 36, and Longmont is just 12 miles east via State Highway 66. Downtown Denver and Denver International Airport are both about 90 minutes away. 


The Northern Front Range of the Rocky Mountains, stretching from Fort Collins to Colorado Springs, offers endless opportunities for outdoor recreation and sophisticated entertainment, amid some of the most beautiful scenery in the western United States, with 14,000-foot peaks, the rugged Continental Divide, mountain lakes, rivers and fishing streams. Nearby public lands include the vast expanses of the Arapaho, Roosevelt and Pike National Forests, as well as Rocky Mountain National Park and the Indian Peaks Wilderness Area. Boulder County’s Open Space and the City of Boulder’s Open Space and Mountain Parks systems, including the world-renowned Flatirons and Chautauqua Park areas, provide thousands of acres for recreation and virtually limitless hiking, biking, climbing, and other outdoor options. All of these world-class recreation destinations are just short drives away from North Middle Fork Ranch. Seemingly endless expanses of the national forest are just a hike or ride across the boundaries of North Middle Fork Ranch. 

Nearby Lyons hosts a series of summer bluegrass festivals and is a major hub, along with Telluride, for Colorado’s acoustic music scene. Estes Park, the gateway to Rocky Mountain National Park, is a bustling mix of boutiques, shops, restaurants, pubs and local businesses serving visitors to one of America’s most popular national parks. Boulder, of course, is a world-famous destination in its own right, home to the University of Colorado Buffaloes, the National Center for Atmospheric Research, the laboratories of the federal National Institute of Standards and Technology, myriad high-tech, biotech and aerospace industries, and all the restaurants, cultural amenities and pedestrian pleasures – such as the famous Pearl Street Mall – for which this vibrant city at the base of the Flatirons is famous. And the endless offerings of Denver, the fast-growing “Queen City of the Plains,” is just another half hour away. 


Elevations at North Middle Fork Ranch range from valley bottoms at around 6,300’ to peaks and outcrops at roughly 8,200’. The principal building envelope areas where a complex of private improvements can be built lie around 7,500’. The property enjoys a mild mountain climate, typical of the eastern slope of the Front Range. Boulder County enjoys some of Colorado’s most inviting weather with an average of 245 sunny days a year and year-round low humidity. The average high temperature in July, the hottest month, is 86°F while the January average low is 17°F. Though nighttime temperatures can dip below zero in winter, extended periods of extreme cold are not common. The area receives about 18 inches of rainfall and 77 inches of snow a year. Unlike the higher elevations, the snow rarely accumulates to significant depths. With low humidity and sunny days to moderate temperatures, it’s common to see locals walking through Lyons and Boulder, and hiking and biking the endless local routes and trails, in shirtsleeves in wintertime. It’s a local truism that you can be on your cross-country skis one day, and on your bicycle the next.


North Middle Fork Ranch was, until its purchase in 1993 by the current owner, part of the local cattle ranching landscape that began around the turn of the 20th century. During that era, many significant larger parcels containing the best grasses and access to water were homesteaded, and patents were issued by the United States to convey title to private ranchers. NMFR was for many years the “summer unit” of the Hall Ranch, with headquarters at lower elevations west of Lyons. The Halls’ livestock were transported each spring to the higher, lusher ground of NMFR, where they spent the summer grazing the good grasses of the ranch and forage on the adjacent national forest. For the most part, North Middle Fork Ranch is as it always was. Its internal primitive ranch roads and trails were for generations used to move cattle from pasture to pasture; now they provide a private recreational trail network for hiking, biking and horseback riding adventures. Where cowhands once moved, managed and gathered their livestock, the owner can venture into the virtually limitless, spectacular and lightly visited portions of the Roosevelt National Forest along the southerly rim of the wild and roadless North St. Vrain Canyon.

Area Attractions
It’s no accident that Boulder and Longmont regularly make the lists of the most livable and healthiest cities in the United States. The weather is terrific, the outdoor activities are endless, locally sourced organic foods are plentiful, and culture, art and music abound. Having the spectacular Rocky Mountain National Park just up the road doesn’t hurt either.

Home to the University of Colorado, which boasts five Nobel laureates and numerous nationally recognized academic departments, Boulder has been a magnet for learners, seekers, artists, musicians and entrepreneurs for more than a century.  With a population of about 100,000 people, the city has the feel of a small town and the amenities and sophistication of a larger city. Scientific and spiritual organizations co-exist in an atmosphere of tolerance and open-minded learning. Naropa University, a secular Buddhist-oriented school founded by Allen Ginsberg and Chogyam Trungpa Rinpoche, is here. So are the National Institute of Standards and Technology, home to the atomic clock, and the National Center for Atmospheric Research.

The spectacular Flatirons, mountainous rock formations of conglomerate sandstone, frame Boulder’s western edge, beckoning outdoor enthusiasts. The region is rich with hiking, mountain biking, and horse trails, as well as sporting activities of every kind. The Pearl Street Mall, a pedestrian avenue of shops and restaurants, pulses with activity throughout the seasons. Perhaps no city in America has more places that sell healthful organic food and homeopathic remedies.

Over the years, Boulder has been named “Best Running City,” “Thinnest City,” and “No. 1 Green & Clean City.” Seventeen magazine rated it “Top 10 Place for Teens.”  Redbook magazine mentioned it as one of the “Top 10 Great Cities for Working Mothers,”  Men’s Journal ranks Boulder “Best Overall City,” and Boulder is one of Outside magazine’s “Best Outside Towns.”

Except for partial perimeter fencing, the remains of a historic cowhand bunkhouse, and a few surviving corral structures, North Middle Fork Ranch is unimproved. The current owners, who maintained their own headquarters, stables and arena a few miles away in the town of Riverside in the South St. Vrain Canyon, enjoyed the ranch for more than 25 years strictly for cross-country horseback riding, hiking, hunting, and other private enjoyment of the land’s exceptional natural, scenic and wildlife values.

Water Rights

Although there are no adjudicated water rights associated with NMFR, springs and seeps throughout the property maintain rich meadow areas and aspen groves. The lushness of the landscape and significant evident groundwater resources suggest there should be little difficulty establishing productive wells to service the significant improvements allowed to be constructed and used on the property. 

Mineral Rights

Any and all Seller owned mineral rights are included in the sale. 


Total real property taxes for 2019 are estimated to be approximately $266.38.

Recreational Considerations

The North Middle Fork Ranch owner and guests may use the ranch for private, non-commercial hunting. The owner may obtain and rely on an opinion from Colorado Parks & Wildlife with respect to the quantity of game that can be harvested from NMFR in any given year consistent with generally accepted principles of game management. NMFR is located in Colorado Game Management Unit 20. GMU 20 comprises more than 1,200 square miles, of which 58 percent is public land, and is managed for Big Game species.  

Except as may be reasonably necessary for management of the property or for emergency purposes, outside the two building lots selected by the owner for improvements, motorized vehicle use on North Middle Fork Ranch is confined to existing ranch roads. Motorized off-roading is not permitted because of its potential adverse impacts on NMFR’s exceptional natural features and values.
