SCORR Volunteers Save Our Trails


We Need Help Building New OHV Trails in Summit County!

Check out The current volunteer trail days:

Summit County Off-Road Riders (SCORR) has received approval to construct a 21-mile single-track trail system on Tenderfoot Mountain in Summit County Colorado. Working in conjunction with the Friends of the Dillon Ranger District, a volunteer work day is scheduled this summer to begin trail construction:

• Bring: Long pants and eye protection. Work gloves, hard hats, and tools will be provided.

• Extra Credit: If interested in being a crew leader, openings are available. Please inquire.

• Please RSVP to: Jeff Stackhouse at

• More Info: Visit or contact Scott Fussell at, 970-262-3449

SCORR and the Dillon Ranger District are still committed to completing the reroute of the One Step Over/Cabin Trail in the Golden Horseshoe before the snow flies and need your help! 9/22/15,  9/23/15, and all week 9/27-10-3, the Dillon Ranger District will be out working on the trail from 9-7 each day. The goal is to complete a few miles of trail. I am challenging each of you to work at least several hours on this project and get two of your friends to also help! Please contact Ken Waugh of the Dillon Ranger District at 970-390-2748 or email him

COHVCO has been very supportive of SCORR and our relationship with the Dillon Ranger District. This year, our Tenderfoot Mountain Motorized Trail System Project won the COHVCO "Project of the Year Award" and Ken Waugh of the USFS Dillon Ranger District won the "OHV Manager of the Year Award"! Ken, who is also a member of SCORR, has put in countless hours both on and off the clock to help our cause. Without Ken's dedication, we would most likely not have any legal trail to ride in Summit County and certainly none of the projects we are currently working on would be a reality. None of us, me included, have put in as much time as Ken to see these projects thru. If we expect o realize the completion of the trail reroutes in the Golden Horseshoe and the Tenderfoot Mountain Project that will increase our legal singletrack mileage from 6 to 35 miles in Summit County, we can't leave it all up to Ken - YOUR SPORT NEEDS YOU! Contact Ken and let him know when he can expect your help!

Tenderfoot Mountain Changes Implemented this Summer

Silverthorne, Colo. (July 14, 2015) – This summer, the Dillon Ranger District will be implementing actions that were made in the 2014 Decision Notice for the Tenderfoot Mountain Motorcycle Trail System.  The Tenderfoot Mountain Road (#66.2B) in Frey Gulch will be closed and rehabilitated in order to improve water quality and provide improved habitat for multiple fish and wildlife species.  

 Fish populations in Frey Gulch are being negatively affected from sediment sources running from the road directly into the stream channel.  The stream is currently in a diminished stream health class and fine sediment is contributing to a loss of pool and spawning habitat.  Rehabilitation of the road will stabilize soils and minimize active and future sediment delivery to Frey Gulch.

The road accesses an area identified in the White River National Forest Land and Resource Management Plan as a Forested Landscape Linkage.  This is an area managed as a movement corridor for larger fauna such as carnivores. Tenderfoot Mountain is home to a residential elk herd that uses this area year round. Recent studies also show that Tenderfoot Mountain is part of a statewide movement corridor for Canada lynx. “Restoration of this road will provide increased availability of habitat for all wildlife species including important prey species for Canada lynx.” said Ashley Nettles, District Wildlife Biologist. 

The road will be closed and rehabilitated using heavy equipment and hand work.  The compacted soil will be broken up or “ripped” to allow native vegetation to re-establish in the road corridor. Soil amendments will be added to the ripped road bed to increase nutrient availability to native vegetation. Additionally, native plant seeding and tree planting will occur within the road bed in order to facilitate forest growth.  Steep sections will be re-contoured to deter erosion.  This work will occur in mid-July and August 2015.     

The road closure will affect hunting access in the fall.  To offset impacts, Road 66.2A will be opened from September 1 to November 23 to full sized vehicles which can be driven about one mile and gain about 1,000 feet in elevation.  From that point, ATVs can be driven another mile to Tenderfoot Mountain (11,441 feet).  This will allow for limited motor vehicle access for hunters.  ATVs have a maximum width of 50 inches. 

Trail construction for the Tenderfoot Mountain Motorcycle Trails project has begun and will be completed in 2017.  An Off Highway Vehicle (OHV) grant-funded 4-person crew will build about six miles of trail this summer with help from Summit County Off-Road Riders, Friends of the Dillon Ranger District, Volunteers for Outdoor Colorado, Rocky Mountain Youth Corps, National Forest Foundation and the Colorado Statewide OHV crew.

OHV riding areas in Summit County:


Golden Horseshoe Recreation Opportunity Guide

Golden Horseshoe Map

These identify the Golden Horseshoe Trails that are open to motorcycles. The most important message to off-highway motorcycle enthusiasts is that all roads and trails are closed to your use, unless it is on the MVUM and there is a sign inviting your use at the beginning of the route. All trails are closed to motorized uses unless posted open. It is also very important that SCORR members demonstrate that they can stay on designated motorized routes only in the Golden Horseshoe area.

Our Mission Statement:

“SCORR promotes responsible off-road motorcycle recreation in Summit County, Colorado. We work in cooperation with local land managers to preserve our riding privilege and a high-quality recreation experience. We advocate good stewardship of our public lands and respect for other trail users. We can be recognized by the example we set when riding, our volunteer work in maintaining trails, and our efforts to educate other off-road motorcycle users.”

Our Land:

75% of land in Summit County, CO is USDA Forest Service. 25% of this land is designated as wilderness (no motors or groups larger than 25 allowed). Most riding is moderate to extreme with our new OHV park in Dillon specifically designed for beginners, children and families.

Our History:

SCORR started in the 1980's as SCORE, or the "Summit County Off-Road Enthusiasts" when the county did a land trade that included the existing riding area in Dillon. SCORE members worked with the County Commissioners in public meetings and were given permission to ride in these areas, but because of liability fears, the county did not make it an official OHV area. We could still ride there, but we could not do improvements, like smoothing the exisiting motocross track.

SCORR was reborn in the 1990's because of a proposed "Closed Unless Marked Open" law. We fought it and the result has been lawsuits and limbo until 2012. We have now lost many of our trails.

Today SCORR is active in our community with members attending public meetings with local, county, state and federal officials. We schedule and volunteer for several well attended trail maintenance days and help with many mountain bike races.

SCORR is a 501(c)3 non-profit Organization and is allowed grant money for trail improvements. This includes trails and parking areas for hiking, biking, horseback riding and even...OHV's!

SCORR Endorses the AMA's
support of helmets.



The American Motorcycle Association's position in support of voluntary helmet use:

"The American Motorcyclist Association (AMA) has always encouraged the use of helmets, gloves, sturdy footwear, and protective garments in general, as part of a comprehensive motorcycle safety program to help reduce injuries and fatalities in the event of a motorcycle accident.

The Association will not oppose laws requiring helmets for minor motorcycle riders and passengers. It believes that many young motorcyclists and passengers may lack the maturity to make an informed decision regarding the use of motorcycle helmets.

Although the Association strongly encourages helmet use by all motorcyclists, it maintains a long-standing fundamental belief that adults should continue to have the right to voluntarily decide when to wear a helmet....The Association further believes that helmet use alone is insufficient to ensure a motorcyclist's safety."

Full Version of the AMA's position on helmet use


Colorado Helmet Law:

Requires a person under 18 years of age who is an operator of a motorcycle or motorized bicycle or who is a passenger on such vehicles, to wear a protective helmet that is designed according to certain specifications; sets the penalty and surcharge for failing to wear the helmet; sets an additional surcharge for each violation to be deposited in the state Traumatic Brain Injury Trust Fund.


80% of motorcycle crashes are fatal vs. 30% of automobile crashes.

$10,122 average treatment with helmet vs. $30,365 without a helmet.

A helmet reduces the chance of a fatal injury in an accident by 29%.

A helmet reduces the chance of a debilitating brain injury in an accident by 67%.

Urban Myths:

"Claims have been made that helmets increase the risk of neck injury and reduce peripheral vision and hearing, but there is no credible evidence to support these arguments. A study by J.P. Goldstein often is cited by helmet opponents as evidence that helmets cause neck injuries, allegedly by adding to head mass in a crash. More than a dozen studies have refuted Goldstein's findings. A study reported in the Annals of Emergency Medicine in 1994 analyzed 1,153 motorcycle crashes in four midwestern states and determined that "helmets reduce head injuries without an increased occurrence of spinal injuries in motorcycle trauma."

Orsay, E.M.; Muelleman, R.L.; Peterson, T.D.; Jurisic, D.H.; Kosasih, J.B.; and Levy, P. 1994. Motorcycle helmets and spinal injuries: dispelling the myth. Annals of Emergency Medicine 23:802-06.

"Regarding claims that helmets obstruct vision, studies show full-coverage helmets provide only minor restrictions in horizontal peripheral vision. A 1994 study found that wearing helmets restricts neither the ability to hear horn signals nor the likelihood of seeing a vehicle in an adjacent lane prior to initiating a lane change. To compensate for any restrictions in lateral vision, riders increased their head rotation prior to a lane change. There were no differences in hearing thresholds under three helmet conditions: no helmet, partial coverage, and full coverage. The noise generated by a motorcycle is so loud that any reduction in hearing capability that may result from wearing a helmet is inconsequential. Sound loud enough to be heard above the engine can be heard when wearing a helmet."
