Someone has cut down a “safety fence” on a trail in Morrison, Colorado within a day after its construction by local land managers, Jefferson County Open Space (JCOS). The land managers erected the fence to keep mountain bikers from riding down a steep rock wall, putting their own safety and that of others at risk. Denver news channel Fox 31 KDVR first posted this news story on February 9.
Now that the lead and the skeleton of the story are up front and visible, let’s take a deeper look at some of the questions this poses and why folks are taking issue with both actions.
The Dakota Ridge trail in Morrison is either loved or hated by most local mountain bikers. The trail, about three-and-a-half miles in length is notoriously technical, with off-camber ridges and slabs, drops and small jumps, exposure, and ledge upon ledge. With riders fighting to get up and down the trail, most find themselves in a bigger, slower gear and with less speed compared to a lot of other trails in the area. Often, the most dangerous things on the trail for a mountain biker are off-leash dogs, hikers with headphones in, and tourists’ small children jumping across the trail.
Visitors and tourists can check out some of the 300 dinosaur tracks and fossilized footprints on the ridge, via the slow-moving bus tour or by foot. According to the Dinosaur Ridge non-profit, there are about 200-250,000 visitors every year who hike around the hogback. In total, Dinosaur Ridge says there are 15 fossil and geological sites on the ridge.

The world’s first Stegosaur discovery took place at the ridge. There are tracks from three distinct dinosaurs and one “crocodilian” track. They say the roadway through the ridge was built in 1937, and they discovered new layers and fossils when they cut through the hogback. It has since been designated as a National Natural Landmark.
Near the end of the first section of trail, which intersects with a road closed to all vehicles except bus tours, the singletrack switchbacks down to the road, before mountain bikers travel up and across the road to the next section of the Dakota Ridge trail. On the second-to-final switchback heading toward the road, an open wall drops from the trail down to the road. Mountain bikers brave enough to skip the trail and ride down the steep slab can do so, but not without challenges, and not with any sort of endorsement from the county. This is where and why JCOS constructed the fence.

“We absolutely identified this was a risk to anybody who may be walking or traveling up or down that hill on the roadside,” JCOS told Fox 31. According to the KDVR story, “cyclists had been cutting off the trail near the bottom, and flying into the roadway below.”
“Flying” is an exaggeration though. For mountain bikers to successfully get down this unofficial feature, they need to keep the brakes engaged, navigate a break in rock and vegetation growing in the wall, and slow down before the road. There is a big compression at the bottom of the wall – likely a drainage feature – and carrying too much speed with poor body position can easily result in going over the bars and eating asphalt.
The sight line is also wide open, so if mountain bikers were to consider riding the wall, they would have to blatantly disregard the safety of any pedestrian at the bottom of the wall and the pedestrian would have to be nearly oblivious to something happening right in front of them.

I’m not saying this can’t happen, but it seems unlikely. Given the context though, it’s safe to assume that JCOS doesn’t care about the variables which put riding this feature in a mountain biker’s favor. They care about the chance that something could happen.
On Monday, JCOS installed a 56-foot fence on the wall, with posts planted into the prehistoric rock. By Tuesday morning, the fence had been removed. Land managers are asking for any information that may lead to a suspect. On a ranger’s Twitter account, proponents of the fence-removers voiced their own opinions.
“This ‘fence,’ that is ironically drilled into the very rock it’s ‘protecting,’ is such a pathetic and predictable action by JCOS. Of all the areas to spend time and resources…”

Therein lies the debate. The fence was drilled into the rock for safety by land managers, but what is it really protecting? If the rock itself was at the forefront of the discussion, JCOS would have constructed a fence that had zero impact. If people actually being on the wall was an issue, they would have constructed a fence at the base too, like those already constructed at some of the paleontological sites, so that children aren’t running up the wall, jeopardizing anything of historical significance.
The argument for the fence then rests solely upon the safety of visitors – both mountain bikers and pedestrians in the area, but as mentioned above, it’s hard to even entertain riding the wall without knowing absolutely that you can complete it without hurting yourself or anyone else. Put another way, it’s not a feature that a rider can bail on if they change their mind, which already deters most mountain bikers, except experts from riding it. Effectively, this only shuts down access on this feature for a sliver of riders, but at what cost, and what comes next?
There are arguably several more dangerous features on Dakota Ridge alone, and throughout the entire JCOS trail network. They would be much easier to fence off, without anyone crying foul over what’s at stake for protection. Yet, this wall is singled out by land managers, and MTBers are again singled out as a user group which can’t be trusted to make their own decisions regarding safety, even though there are features just as risky as this wall throughout the entire trail, for both hikers and mountain bikers.

All of this isn’t to say that anyone should go out and start hacking away at government structures we disagree with. That would be criminal and a waste of land management resources, which are usually rather dry anyway and often prevent regular trail maintenance or the construction of new trails from happening.
So, who is in the right? Mountain biking access is granted on most multi-use trails across the nation. Mountain biking is an inherently risky sport. At what point should land managers completely disallow a user group from using parts of the trail? At what point are they protecting resources or harming them even more? Who is on the right side of the fence? As of now, a replaced version is standing again.
As a MTBer, i try to avoid multi-use trails, and especially those with increased traffic, and even moreso avoid tourist areas. I do support shared trail use, within reason. This MTB feature appears to conflict with hikers and visitors of the tourist attraction. To me, this doesn’t pass my own reality check: “just because you can, doesn’t mean you should”
Some have commented here advocating disregarding the rules, signs and fences put up by the JCOS and possibly even pulling the fence down. I’d like to add some perspective from 70+ years. I grew up in Ohio in the era where the Cuyahoga river caught fire over a dozen times, culminating in the fire of 1969 which became a banner for the rising environmental movement. I remember the first Earth Day and the passage of the Clean Air and Water Act. I also remember the publishing of The Monkey Wrench Gang in 1975. Living in Ohio at the time, I had a certain perspective about the eco-warriors lionized in the book. If you read the reviews of the book today on Amazon, there are glowing reviews who regard the actions of the Monkey Wrench gang as heroic and just. However, after I moved to Montana I became aware of a different perspective – one where the destruction of a bulldozer meant tens of thousands of lost dollars inn equipment to someone, and loss of a job and income to others. This was a perspective where someone spiking a tree could easily cause the death or injury of a logger. I discovered with some surprise that for many in the West, “environmentalist” was not a compliment and was associated with anarchy and destruction. I now feel that although Edward Abbey may have won a few battles with the book, he set the environmental movement back and from which it has yet to fully recover. It was amazing to me to move to an area with multiple superfund sites and yet see so many people have such adverse feelings about the movement, and I conclude that what many of my friends regarded as rugged individual eco-warriors were regarded by others as potentially dangerous criminals.
In Helena, Montana, mountain bikers co-exist pretty well with other users. Recently some new biking trails have been created in the Elkhorns in areas traditionally used mainly by horse people and hikers, and I have become aware that there is a significant part of trail users who do not regard mountain biking favorably. The willful destruction of safety fences and the disregard for rules set down by managing bodies has potential to completely block access to trails. My personal opinion – and you can differ – is that these issues need to be settled within the bounds of the law and rules set down by land managers. Discussing issues with land managers will bear more fruit than destroying the features they have set up with the intention of promoting safety. Just my opinion.
Here we go with the politicians directing the land managers to obstruct mountain bikers. People will do the typical removal thing as usual. Nothing new here other than once again the agenda of a select few is to dictate to those minions known as their subjects and the dictator is whining about the opposition to their agenda.
Typical…
Damn, I got a demerit for stating the obvious. Go figure!
It is going to happen regardless and while I don’t condone it or participate in such actions, I see it in many regions. stuff happens and those that don’t agree may do the vandalism even if it does cause a closure to bikes in the future. Fvck, I actually have to spell it out…
This is a tough one. The trail is in my backyard, I ride it several times a year and have lived here since the days when we used to be able to drive the shortcut to Red Rocks. I’ve seen how the area was used before as well as the changes now put in place given the national landmark and influx of foot traffic on the trail and road below. I also climbed for 10 years before discovering my greater outdoor passion, and have seen across multiple environments the near-universal debates around land use, access, impact, common decency juxtaposed with common sense, and who’s ultimately right. I tend to be of the camp that anybody pursuing a recreational endeavor that has a risk factor bears the responsibility for being aware of and ensuring not only their own safety but also the safety of those in proximity, within reason. And I’ve also been on the receiving end, no matter what I try to do to be considerate, of fellow mountain bikers either out of control for lack of experience or disregarding those around them no matter what their motivations may be. All that in mind, we have to defer to the school groups and other people at the bottom of the hill who would simply panic if a biker came rolling down out of control. You can’t guarantee a scenario where that may not happen. Neither can the county. And in a common suburban space, they can’t lean on what a handful of elite enthusiasts think they can handle without issue. Especially not when an already established trail is literally to the right. I get that drilling postholes is a tad ironic, but wouldn’t it be more detrimental over the course of time for anybody, hiker, biker, et al., to wear out a foot path when volunteers have painstakingly already established one right there? Not to mention, though the pandemic has been a boon to this industry, there is a lot more inexperience out there turning cranks. I want them to love this sport…just as much as I don’t want them hurtling down a feature because they’ve got the ambition and saw someone else try.
I do want them hurtling down a feature because they have ambition and saw someone else do it, that’s the point of the sport for me. To push yourself and find the limit of what you can do on 2 wheels. Anyone whose sole focus is safety shouldn’t be leaving their house in the first place. Weve gone way overboard with safety as a society and it’s raising a generation of cowards and p***ies as a result. To quote Mike rowe – “safety third”
Having fought the trail access wars, it’s important to consider how fragile trail access is, especially in highly populated areas like Denver.
Sounds like you’re saying we should bend over and take it when the govt builds fences to appease a bunch of whiners. Have fun with that, I’ll continue going over or around them as I have been doing for some time. Most of these places don’t have the resources to enforce their own stupid rules so why follow them? If a rule isnt enforced then it doesn’t exist. Didn’t get into this sport to blindly follow rules since that isn’t a good way to live in general. If I was into rules I’d buy a road bike. 🖕to safety. I also don’t live near highly populated areas, especially a leftist hellhole like denver and I’ll just add your trail access issues to the long list of reasons I never will. I don’t know anything about the spot where this fence is, but if they built one in pisgah to keep people off a popular rock face, it wouldnt stop a single person. They’ve already tried, failed, and given up
I have a young friend who is now a paraplegic because of that attitude.
Jeffco Open Space isn’t Moab, and the land managers have a responsibility beyond catering to the experience of a small user group. Anyone that thinks that closing this off to bikes was solely to disappoint MTB riders is either stupid, or selfish.
One of the basic premises of responsible MTB riding is staying on the designated trail. Make no mistake, if you can’t handle that, it’s your problem, not theirs.
I ride this trail two to three times a week, weather permitting. Since covid the trail receives a lot of traffic and the lines have widened considerably. That is caused by hikers and bikers trying to avoid each other and avoiding difficult trail features. This part of the trail is a good example of that.
Bikers choose the slab to avoid a 180 degree switchback with consequences. That path is way more difficult than dropping down the rock face as a bailout.
The road below does not allow car traffic and partitions the road for bike, pedestrian and tour buses. The pedestrian traffic is designated right at the base of the rock face. That was an accident waiting to happen. I wouldn’t want to be the rider who t-bones a kid that happens to get in the way.
There are enough challenging features on this trail to satisfy any ‘expert’ rider without going off trail.
Duvaldevil, You’re fortunate to live and ride in an area with no user conflicts. As has been said in other venues, “Our best thinking got us here.”
Screw the fence and screw the government. Bolt cutters ftw
