Con Cuidado Y Communidad

By Sierra McGivney

Driving towards Highway 285, we pass strips of red rock cutting through the foothills of Morrison in Colorado’s Front Range, chasing the promise of new climbs. In the front seat, Josh Pollock describes the Narrow Gauge Slab, a new crag he has been developing in Jefferson County.

Pollock is the type of person who points out the ecology of the world around him. As the car weaves along the mid-elevation Ponderosa Pine forest, Pollock describes how we’ll see cute pin cushion cacti, black-chinned or broad-tailed hummingbirds, and Douglas-fir tussock moth caterpillars.

We pull into a three-level parking lot about seven miles down the Pine Valley Ranch Road. With no cell service and heavy packs, we set off along an old railroad trail toward the crag. Not even ten minutes into our walk, Pollock turns off, and we are greeted by a Jeffco trail crew building switchbacks to the crag.

As we approach the base of the Narrow Gauge Slab, Pollock picks up the dry soil. Fine granular rocks sit in the palm of his hand as he describes how this is the soil’s natural state because of Colorado’s alpine desert climate.

Unsurprisingly, Pollock was a high school teacher at the Rocky Mountain School of Expeditionary Learning in a past life; now, he is a freelance tutor and executive function coach. A Golden local and climbing developer, he has been working to develop the Narrow Gauge Slab since 2021.

Pollock first became interested in route development in 2011. He wasn’t climbing much then, instead focusing on raising his second child. Flipping through a climbing magazine one day, an article about route development caught his eye.

Between naps, diaper changes, and bottle-feeding cycles, he would go for quick trail runs in the foothills by his house in Golden. During his runs, Pollock noticed cliffs that weren’t in guidebooks or on Mountain Project. He began imagining how future climbers might experience and enjoy the rock.

“The routes I can produce for the community are moderate and adventurous but accessible,” said Pollock.


Climbing in Clear Creek is a high-volume affair. Jeffco Open Space (JCOS), the land management department for Jefferson Country, started to recognize this during the five years from 2008 to 2013 when climbing in the area exploded. With such a high volume of all kinds of outdoor enthusiasts recreating in Jefferson County, including climbers, adverse impacts on the land followed, including increased erosion and propagation of noxious weeds. Previously, Jeffco Open Space took a more hands-off approach when it came to climbing. However, because their mission is to protect and preserve open space and parkland, they concluded the increased popularity of climbing in the area warranted more active management.

While Jeffco Open Space had a few climbers on staff, they quickly realized they were not qualified to make decisions surrounding fixed hardware and route development. They turned to the local climbing community.

In 2015, Pollock began developing routes at Tiers of Zion, a wooded crag overlooking Clear Creek Canyon in Golden. In 2016, Jeffco Open Space established the Fixed Hardware Review Committee (FHRC) with Pollock as one of its seven advisors—now eight. The FHRC provides expert analysis to Jeffco staff members regarding applications for installing or replacing fixed hardware in the area (including slacklining). As a formal collaborative effort between local climbers, route developers, and Jeffco land managers, it is one of the first of its kind in the country.

Eric Krause, the Visitor Relations Program Manager and Park Ranger with Jeffco Open Space, deals with literal and figurative fires weekly and is responsible for all climbing management guidelines. He sits in on meetings and speaks for Jeffco.

“I think really good communication between a landowner or land manager and the climbing community is imperative,” said Krause.

Since 2015, Jeffco Open Space has invested more than 1.5 million dollars to improve the access and sustainability of existing crags by stabilizing eroding base areas, building durable and designated access trails, supplying stainless steel hardware to replace aging bolts, supplying portable toilet bags to reduce human waste at crags, and rehabilitating unsustainable areas.

If new routes for an existing crag are submitted to the FHRC via their online form, it’s already an impacted area, so it’s more likely to be approved. During their quarterly meeting, each member of the FHRC reviews the submission and discusses whether the new route(s) is a worthwhile addition to climbing in Jefferson County. A route that might be denied is within the 5.7-5.10 range at a crag with limited parking and heavy trail erosion, because routes in that range tend to attract the highest volume of climbers.

“We don’t really want to be adding more sites that are just going to degrade, and we’d rather get in there ahead of time and build it out to where it’s sustainable to begin with,” said Krause.

If a new crag is submitted, this triggers an entirely different internal review process called the “New Crag Evaluation Criteria (NCEC),” overseen by Jeffco Open Space. Every individual on the JCOS internal climb- ing committee (comprised of staff from the Park Ranger, Trails, Natural Resources, Planning, Park Services, and Visitor Relations teams) independently rates the new crag based on various categories: potential access trails, environmental considerations, parking, traffic, community input, organizational capacity, visitor experience, and sanitation management. They then average all of the scores for the submitted crag, and its viability is discussed.

To combat the ever-growing need for accessible places for new climbers, families, guided parties, and folks looking for high-quality moderate climbing, Jeffco asked the FHRC and others if they could find a beginner-friendly new crag in the southern part of the county, where there are fewer climbing areas.

According to Krause, Pollock took this request to heart and started looking all over the county for a new crag. He struggled to find a place with adequate parking, access to bathrooms, and the ability to build new trails on stable ground. “Threading that needle is hard, and it took several years and maybe half a dozen possible locations to find one that worked,” said Pollock.

An open space staffer suggested he look at the area that is now the Narrow Gauge Slab.

When Pollock first walked along the base of what would become a major project in his life, the Narrow Gauge Slab, he felt compelled by the rock’s position, composure, and aesthetic. He began imagining routes to climb. The crack features broke the wall up into clean-looking panels.

For Pollock, unlocking the potential of a crag is an unanswered question until the last moment.

“There’s a great drama to it,” said Pollock.

He proposed the crag in 2021. The Narrow Gauge Slab would become the first crag approved under the NCEC framework.

“I think what I’m most excited about is that this whole endeavor has been collaborative and cooperative with Jeffco Open Space from the get-go,” said Pollock.


Jeffco is constantly playing catch up with erosion damage in an arid climate like the Front Range. At the Narrow Gauge Slab, Jeffco had the opportunity to identify and implement adequate infrastructure for the area before route development began.

“In some ways [it is a] first of its kind experiment, with building a sustainable access trail and stabilizing belay pads on the base area and things like that before lots of user traffic shows up,” said Pollock. The Boulder Climbing Community, the AAC Denver Chapter, and Jeffco collaborated to stabilize and build out the area before the crag opened to the public.

According to Pollock, the crag does not have a theme. Since this crag has many developers, and sometimes multiple developers to any given climb, the route names have personal meaning to the developers or the circumstances of the route. But when you look closely, a kaleidoscope of meaning comes into view: collaboration.

His primary objective with the Narrow Gauge Slab was to develop a moderate and accessible crag, but the project evolved into something much more: mentoring climbers on route development. He reached out to different LCOs, such as Cruxing in Color, Brown Girls Climb Colorado, Escala, Latino Outdoors, and the AAC Denver Chapter, inviting members to participate in a mentorship program based on route development. In total, there are 16 mentees and five mentors, plus Pollock. Despite uncovering the crag, Pollock has barely put any hardware in.

Route development is a niche aspect of climbing that requires extensive resources and knowledge. Pollock wanted to invite new groups of climbers who might not consider themselves route developers but were interested in learning. He is pleased that the mentees have learned from this project and are developing new routes near the Front Range. Some mentees have been swallowed whole by the development bug. Lily Toyokura Hill is so enthused that she was recently appointed to the nearby Staunton Fixed Hardware Review Committee.

Hill and Ali Arfeen collaborated on Bonsai, a 5.7 climb featuring a tiny tree sticking out of the rock. Hill, who is shorter, and Arfeen, who is taller, would take Pollock’s kid’s sidewalk chalk and mark key holds they could reach, helping to determine where they would place bolts when they were developing the route’s first pitch.

To the left is Con Cuidado y Comunidad (With Care and Community), a three-pitch 5.6 put up by (P1) Sharon Yun and AAC employee Xavier Bravo, and (P2+3) Maureen Fitzpatrick and Cara Hubbell.

While Pollock racks up to lead Con Cuidado y Comunidad, Douglas-fir caterpillars inter- rupt our conversation. Pollock stops, pointing out the fuzzy horned creature on his bag. He describes how their population erupts every seven to ten years. His father was a biology teacher, and both of his children are fascinated by ecology.

On top of Con Cuidado y Comunidad, we picnic overlooking the epic landscape of the South Platte. Pollock explains how climbing at the Narrow Gauge Slab requires what he calls “smedging,” a mix of smearing and edging.

Climbs are littered with minuscule footholds and often require both smearing and edging to climb. Pollock prefers this type of movement: slow and thoughtful.

The last bolt for the Narrow Gauge Slab was drilled on August 19, just in time for opening day on the 24th. Pollock feels immense pride in the crag.

“It is really satisfying to share the crag with folks and give to the community,” said Pollock.

On these south-facing slabs, there are thirteen routes ranging from 5.4 to 5.9+, spread across the crag’s granite rock. You can listen to the babble of the South Platte River as you climb, breathing in the smell of fresh pine needles as you stand up on a tiny food hold. Don’t forget to look out for the Douglas-fir caterpillars inching their way across the rock as you clip the bolts.

Mountain Sense

By Sierra McGivney

Usually, when Balin Miller encounters spindrift ice climbing, he puts his head down, waits for 10 to 20 seconds, and continues climbing. Halfway up the face of the Andromeda Strain, a line on the northeast face of Mount Andromeda in Alberta, Canada, Miller and his climbing partner Adrien Costa encountered an intense spindrift funnel. Thirty seconds passed, then one minute, two. After five minutes, he thought, f*** this, and downclimbed.

Miller was persistent, but the spindrift was relentless. They wasted a couple of hours trying to go around.

“You couldn’t see anything, even if you wanted to push through,” said Miller.

Miller and Costa peered around to where the climbing turned into a chimney. A wall of white snow poured down it. They turned back a pitch before the Hockey Stick Crack, disappointed that they wouldn’t be able to live the lore embedded in that pitch. This wouldn’t be the last time they tested their judgment in the mountains and turned away from an objective.

“I think what gets me most stoked for routes isn’t really how good they are, per se, but a lot of the history involved in it—the route that has some old trip report of people getting really scared on it,” said Miller.

This might be why Miller chose the Andromeda Strain as one of his objectives for this 2023 Mountaineering Fellowship Fund Grant (MFFG) trip. Apart from being one of the most popular yet serious alpine climbs in the Canadian Rockies, it has an epic story. An unsuccessful earlier group tried to ascend the off-width and found it too wide to take anything but one-foot lengths of hewn-off hockey sticks (an eerie, early rendition of the Trango Big Bro). Having no hockey sticks handy in 1983, Barry Blanchard, Dave Cheesmond, and Tim Friesen traversed beneath the off-width and around the corner to a steep snow-choked chimney that became the Hockey Stick Crack.

Miller originally applied for the MFFG from the American Alpine Club to support an expe- dition to the Alaska Range. He was awarded the grant but had to change his trip to the Canadian Rockies due to financial constraints. This grant funds climbers 25 years or younger seeking challenging climbs in remote places. One of Miller’s partners, Adrien Costa, has previously leveraged other AAC grants, including the Tincup Partner in Adventure Grant in 2021 and the Catalyst Grant in 2021 and 2023. The AAC grants can be a great jumping-off point for climbers looking to dream big.

Miller is an ice climber who spends his summers in Alaska and his winters in Bozeman. He got into climbing at the age of 12 and was versed in both ice and rock climbing growing up in Alaska. He is stalwart when it comes to ice climbing, but he has a goofy aura. You can deduce from photos of his trip that he doesn’t take himself too seriously, even on big alpine climbs.

After getting turned around on the Andromeda Strain, Miller and Costa climbed Dreambed (5.11 PG-13) on Mount Yamnuska and enjoyed a sunny day on rock. The two saw a weather window coming up and turned their gaze to Mount Robson or Yuh-hai- haskun (“The Mountain of the Spiral Road”), the highest peak in Canada. Infinite Patience (2200m, VI 5.9 WI5 M5) climbs the north side of the Emperor Face of Mount Robson until it merges with the Emperor Ridge (2500m, V 5.6). This was another big objective for Miller. Despite a solid weather window and the sea- son being in their favor, new challenges awaited the group.

Aidan Whitelaw, six feet, four inches tall with a high-pitched voice, is one of Miller’s best friends. Despite being a student at Montana State University in Bozeman, he’s almost always down to skip class if it means going climbing.

With Whitelaw newly arrived, they set off on their adventure with only one rope, trying to go as light as possible. One rope between three climbers is OK if they don’t need to bail, but just in case, the team brought a Beal Escaper.

Miller wrote in his trip report: “Leaving the parking lot on October 5, Aidan Whitelaw, Adrien, and I hiked into Berg Lake, camping at the base of the face. [We] started up the face at 2 a.m. on the 6th. We soon realized that the direct start was out of condition. It’s usually [three pitches of WI 4 or 5] but turned out to be steep, wet melt- ing snice. We opted to traverse right to gain Bubba’s Couloir. Unfortunately, there was no alpine ice left in the couloir. But the snow climbing was moderate but unprotectable. We eventually decided to bail after the House Traverse, which is roughly halfway up the Emperor Face to the ridge on Infinite Patience.”

Deciding to bail had become extremely obvi- ous to the group. They encountered compact limestone with no cracks and nothing to sling. The group was fine leaving cams or pins but couldn’t find good placements to make anchors. They decided to deadman their ice tools, burying them to create a snow anchor to rappel off.

“It was the worst rock imaginable,” said Miller.

Eventually, they reached a bivy spot and got cozy, fitting three people into a two-person tent and Whitelaw and Miller into one sleep- ing bag. At noon the next day, they started their descent, which consisted of rappelling off V-threads and lousy rock anchors.

The Beal Escaper is a detachable rappelling device that allows you to descend on a single strand without permanently fixing the rappel and sacrificing the rope. To retrieve the rope, the climber tugs the rope ten to twenty times, causing the rope to inch through the Escaper and retrieve the rope.

The group was on 80-degree melting snow. No one had counted how many times they had pulled the rope to disengage the Escaper, but something was wrong. Everyone got quiet. They pulled as much rope through as they could, but ultimately, the rope refused to release. Unable to jug back up the rope out of fear that movement could release the device, and unable to solo back up because of 80 feet of steep bad snow and friable rock, they pulled out as much rope as they could and cut it. Only eight meters of rope were in their hands, the rest of it lost to the mountain. It was dark, and they didn’t know how far they were above the Mist Glacier.

They tied slings together as a pull cord, allowing them to do increments of full eight-meter rappels. Luckily, they were only 100 feet from the bottom.

Twenty-four hours later, Whitelaw was in class in Bozeman, Montana; no one was aware of the epic in the mountains he had just returned from.

After several days off, Miller and Costa hiked into the Lloyd McKay Hut to attempt the north face of Alberta. However, they didn’t get the chance due to a storm and nine inches of wet snow. Miller wasn’t too bummed. Conditions weren’t in their favor, and there was always next year. Both Miller and Costa left after that, and Miller headed to Yosemite.

In November, Miller returned ready to ice climb. He climbed Suffer Machine (200m, WI5+ M7); Virtual Reality (100m, WI6+); Kittyhawk (150m, WI5), solo; and Nemesis (150m, WI6), solo.

He took a short break to visit his mom in Spokane, Washington. Ethan Berkeland flew out to meet him, and the pair drove about 430 miles back up to Canada with Slipstream in sight. Slipstream (900m, IV WI4+) climbs the east face of Snow Dome. It is infamous for it’s exposure to dangerous seracs, avalanches, and cornices, as evidenced by five reports in the Accidents in North American Climbing archive. Jim Elzinga and John Lauchlan first climbed it in 1979, and Mark Twight simul-soloed it in 1988 with Randy Rackliff.

“Anything Mark Twight does is awesome,” said Miller.

The previous fall, Miller had bailed after the approach when it had taken longer than expected, and “it just didn’t feel right.” Both Miller and Berkeland are solid ice climbers. They brought a full rope, a tagline, 14 screws, and a handful of draws, planning to solo the easier parts and pitch out the harder ones. They ended up simul-soloing the entire east face of Snow Dome on November 29 in four hours. In total, the day was thirteen hours from car to car.

After getting turned around on his previous alpine objectives, this was a great achievement for Miller.

Despite the epics on some of his original objectives, Miller found success. Each “failure” in the mountains is a lesson learned for the next climb, maybe even a cutting-edge ascent. The spindrift turned him around on Andromeda Strain, and Infinite Patience was out of condition, but Slipstream proved to be an amazing climb. Sometimes, infinite patience pays off in the mountains.

Teaming Up in DC

By The Editors

As the AAC’s General Counsel and Advocacy Director, Byron Harvison, put it, advocacy work is like “being in charge of building and maintaining an air- craft while it’s already flying in the air—and there are still no guarantees. This work requires constant attention to detail and management of hundreds of relationships.” To your aver- age climber who cares about public lands and advocating for climbing landscapes, the con- stant awareness of legislative processes and advocacy relationships can be exhausting— the runout pitch where you’d rather cede the lead. But for the AAC advocacy team and our partners like Outdoor Alliance, it’s the money pitch—our opportunity to ensure the perspec- tives of our members and other recreationists inform the policies that shape America’s public lands and recreational spaces.”

The Naked Edge

By Hannah Provost

If you had to tell the story of the evolution of climbing within the history of one route, your most compelling choices might be The Nose of El Capitan or The Naked Edge in Eldorado Canyon. In this way, The Naked Edge is a time capsule containing within its memory: the much dreamed-of first ascent finally climbed by Layton Kor, Bob Culp, and Rick Horn; a period defining free ascent by Jim Erickson and Duncan Furgeson in the early 1970s; and one of the few battle- grounds for speed records in the United States. In 1962, Kor and Bob Culp were diverted attempting to aid the steep final edge, and today, climbers have speed climbed the route, bridge to bridge, in a little over 22 minutes. What is it about this climb that has allowed it to be the sketchbook for climbing legends to draw out the evolution of our sport? Anecdotes and artifacts from the American Alpine Club Library and archives provided the answer.
