Burwell Peak

Burwell Peak

Rocky Mountain Arsenal National Wildlife Refuge

Burwell Peak is a rugged 12,673-foot summit in the La Plata Mountains of southwestern Colorado, rising northwest of Durango on the boundary between La Plata and Montezuma counties. Although considerably lower than nearby thirteeners such as Spiller Peak, Babcock Peak, Mount Moss, and Hesperus Mountain, Burwell occupies an impressive position on the southern rim of Boren Creek Basin.

Modern LiDAR-based peak data places Burwell at approximately 12,673 feet, about 19 feet higher than the 12,654-foot elevation printed on traditional USGS mapping. Its roughly 156 feet of prominence means it does not qualify as an independently ranked Colorado summit under the commonly used 300-foot rule.

That modest prominence is deceptive. The usual ascent involves steep off-trail travel, loose rock, approximately 3,500 feet of climbing, careful navigation, and a final summit block with mild exposure. Burwell can also be combined with neighboring Spiller Peak, although that traverse is considerably more difficult than the standard Burwell ascent.

🏔️ A Lesser-Known La Plata Summit

Burwell Peak occupies the southwestern portion of the spectacular La Plata Mountains, a compact mountain group forming part of the greater San Juan Mountains.

The La Platas contain an extraordinary concentration of rugged high summits, including:

Burwell is substantially lower than the famous high cluster to its north, yet its position at the end of the Boren Creek Basin rim makes it an excellent viewpoint and a natural objective for hikers exploring the quieter western La Platas.

🧭 Nearest Higher Neighbor: Spiller Peak

Burwell Peak’s Nearest Higher Neighbor is Spiller Peak, which rises immediately north along the same rugged ridge system.

Spiller reaches approximately 13,134 feet—roughly 460 feet higher than Burwell.

The two summits may appear conveniently close on a map, but the connecting ridge contains a major notch and other rocky obstacles. One established Burwell–Spiller route drops roughly 400 vertical feet below the ridge to avoid the most problematic terrain before climbing back toward Spiller’s south ridge.

For topographic prominence purposes, Babcock Peak is Burwell’s line parent. The hierarchy ultimately continues through Lavender Peak and Hesperus Mountain.

📏 Why Burwell Peak Is Unranked

Colorado mountain lists commonly require at least 300 feet of topographic prominence for a summit to count as an independently ranked peak.

Burwell has only about 156 feet.

Its saddle toward higher terrain sits at approximately 12,517 feet, while the summit rises to approximately 12,673 feet.

Burwell is therefore considered an unranked summit.

That designation says nothing about how difficult or worthwhile the climb may be. Burwell still rises above 12,600 feet, requires thousands of feet of ascent from La Plata Canyon, and offers terrain considerably more challenging than many officially ranked Colorado peaks.

🌄 Southern High Point of Boren Creek Basin

Burwell Peak forms the southern high point along the rim surrounding Boren Creek Basin.

The basin is enclosed by an extraordinary collection of mountains and ridges. Looking north from Burwell, the skyline builds toward Spiller Peak, the Knife, West Babcock, and Babcock Peak.

This position makes Burwell one of the best places for understanding the geography of the Babcock–Spiller mountain complex.

The summit may be lower, but the perspective is exceptional.

🥾 Hiking Burwell Peak

The most commonly described approach begins in La Plata Canyon northwest of Durango.

Hikers follow the rough Boren Creek road—Forest Road 794—into the drainage before branching west and climbing toward Burwell Peak.

A well-documented version of the route covers approximately 6.2 miles round trip with 3,550 feet of elevation gain from a lower parking area along La Plata Canyon Road. It is primarily off trail above the old road and is generally rated Class 2+, with mild exposure around the upper mountain.

The mileage can vary depending on how far a vehicle travels up Boren Creek Road.

🚙 La Plata Canyon Access

From Durango, the usual approach travels west on U.S. Highway 160 toward Hesperus before turning north onto La Plata Canyon Road.

The road follows the La Plata River into the mountains.

After the small settlement of Mayday, pavement gives way to dirt. Boren Creek enters from the west farther up the canyon.

A parking pullout near Boren Creek provides a practical starting point for hikers who do not want to drive the rough side road.

The upper Boren Creek road is steep, narrow, and rocky. Dedicated short-wheelbase four-wheel-drive vehicles may be able to travel farther under favorable conditions, but walking the road avoids introducing a difficult vehicle problem into an already demanding mountain day.

🥾 Boren Creek Road

The first part of the climb follows the old road northwest into Boren Creek.

The road gains elevation steadily while passing through forest toward the upper basin.

Eventually the Burwell route branches from the main track used for approaches toward Babcock Peak.

The route crosses Boren Creek and begins climbing much more steeply west toward Burwell’s southeast ridge.

From here onward, hikers should expect genuine cross-country mountain travel rather than a conventional hiking trail.

🧭 Off-Trail Navigation

Navigation is one of Burwell Peak’s principal challenges.

There is no maintained trail to the summit.

Above Boren Creek, hikers choose their own line through forest, steep slopes, loose ground, and increasingly rocky terrain.

An offline GPS map is useful, but it should be combined with an understanding of the surrounding ridges and drainages.

Useful navigation equipment includes:

USGS La Plata topographic map
Offline GPS mapping
Compass
Saved waypoint for the vehicle
Extra battery power

The route may appear simple on a map, but terrain features can conceal the summit and make descent lines less obvious than expected.

⛰️ The Southeast Ridge

The southeast ridge provides the usual final approach.

After climbing steeply from Boren Creek, hikers reach increasingly open terrain and begin following the ridge toward Burwell’s summit.

The lower ridge contains steep grass, rubble, and loose gravel.

Higher up, more continuous bedrock appears.

The final several hundred feet become more interesting, with rocky steps and several possible lines through the summit block. One experienced route description notes that the rock becomes more solid near the crest but can still flake, so holds should be tested carefully.

The standard route generally remains around Class 2+.

🪨 Loose Rock

Loose rock is one of Burwell Peak’s defining characteristics.

SummitPost describes the eastern slopes of the Spiller–Burwell ridge as containing extensive rotten talus and scree, with Burwell itself particularly rich in unstable material.

That makes careful movement important.

Hikers traveling in groups should avoid climbing directly above one another on steep sections.

Large-looking blocks should not automatically be trusted.

The upper mountain has more stable slabs mixed among the loose material, but continual attention to footing remains necessary.

⚫ Black-Coated Rocks

One unusual feature noted by climbers is the dark coating found on some rocks around Burwell.

Manganese oxide can cover portions of the rock with a nearly black sheen.

The effect adds to the mountain’s already rugged appearance.

This mineral staining reflects the complex geological and hydrothermal history of the La Plata Mountains, where intrusive magma, altered sedimentary rocks, and mineral-bearing fluids interacted over millions of years.

🌋 Geology of the La Plata Mountains

Burwell Peak lies within one of Colorado’s most fascinating mountain complexes.

The Colorado Geological Survey describes the La Plata Mountains as a mineralized Laramide igneous intrusive complex on the southwestern margin of the San Juan Mountains and near the transition toward the Colorado Plateau.

Rather than being formed primarily from surface lava flows, the range was heavily shaped by magma forcing its way into older sedimentary rocks underground.

Intrusions uplifted, fractured, heated, and altered the surrounding rock.

Erosion then stripped away softer layers and exposed the resistant mountain core.

🪨 Burwell and the Boren Creek Monzonite Stock

Burwell Peak has an especially interesting geological relationship with Boren Creek Basin.

Historic U.S. Geological Survey work mapped a major monzonite stock at the head of Boren Creek and specifically photographed Burwell and Spiller Peaks surrounding the intrusive complex. The study also noted strongly altered and pyritized rocks in the basin.

Monzonite is an intrusive igneous rock that forms when magma cools slowly underground.

The intrusive body and surrounding altered rocks helped create the complicated cliffs, gullies, mineralized zones, and loose mountain terrain seen around Burwell today.

⛏️ Mining History

The La Plata Mountains became an important mining region because the same geological processes that created their unusual peaks also concentrated valuable minerals.

Prospectors explored the Boren Creek area and surrounding basins for gold, silver, copper, and other metals.

Old mine workings and roads remain visible on approaches to Burwell, Babcock, and neighboring peaks.

These remnants are historically interesting but can be dangerous.

Never enter abandoned mine openings. Hazards can include unstable rock, hidden shafts, contaminated water, bad air, and rotting supports.

Historic artifacts should also remain where they are found.

📜 Burwell Peak on Early Maps

Burwell Peak has appeared in federal geographic records for more than a century.

The U.S. Geological Survey’s early Gazetteer of Colorado identified Burwell as a peak in the La Plata Mountains situated on the boundary between La Plata and Montezuma counties.

Modern GNIS coordinates continue to place the summit at approximately 37.421° N, 108.090° W.

The precise origin of the name “Burwell” is less clearly documented in readily available federal sources than the names of some neighboring peaks.

🧊 A Glacially Shaped Landscape

Glaciers helped carve the modern La Plata Mountains during colder periods of the Pleistocene.

Ice occupied many of the upper basins surrounding the highest summits.

Glacial erosion deepened valleys, steepened mountain walls, and sharpened ridges.

Boren Creek Basin reflects this combination of glacial erosion and resistant intrusive geology.

Today, frost action continues the work at a smaller scale.

Water enters cracks, freezes, expands, and gradually breaks bedrock apart, contributing to the enormous accumulations of talus and scree around Burwell and neighboring mountains.

🌲 Forest to Alpine Tundra

The Burwell Peak route passes through several mountain environments.

Lower portions of Boren Creek contain subalpine forest that may include Engelmann spruce, subalpine fir, Douglas-fir, and aspen.

As elevation increases, trees become shorter and increasingly scattered.

Eventually hikers cross treeline and enter open alpine terrain dominated by grasses, low wildflowers, rocks, and talus.

That transition provides excellent scenery but also removes virtually all protection from lightning and strong winds.

🌼 Alpine Wildflowers

Summer can bring an impressive wildflower season to the La Plata Mountains.

Depending on snowmelt and moisture, the Boren Creek area may support:

Colorado blue columbine
Indian paintbrush
Lupine
Asters
Cinquefoil
Alpine sunflower
Mountain bluebells

The growing season is brief at elevations above 11,000 feet.

Alpine tundra is also surprisingly fragile, so hikers should favor existing routes, rocks, gravel, and other durable surfaces whenever practical.

🌄 Views From Burwell Peak

Burwell Peak’s summit provides enormous views across the western La Plata Mountains.

Looking north, the drama increases immediately with Spiller Peak and the complex Babcock Peak skyline.

Beyond them rise Mount Moss, the summit towers of Lavender Peak, and massive Hesperus Mountain.

To the south, the western La Plata ridge continues toward Gibbs Peak, Star Peak, Madden Peak, and Parrott Peak.

Farther west and southwest, the landscape opens toward the Colorado Plateau and Sleeping Ute Mountain.

🏔️ Burwell Peak and Spiller Peak

Spiller Peak is Burwell’s most important neighboring summit.

Spiller is roughly 460 feet higher and forms the next major high point northward.

Strong climbers sometimes combine the two mountains.

However, the direct connection is complicated by a deep notch immediately north of Burwell and additional rocky obstacles. An established route descends about 400 feet to bypass these problems before traversing toward the saddle and climbing Spiller’s south ridge.

The Spiller portion introduces Class 3 scrambling and serious exposure.

For most hikers, Burwell alone is the more straightforward objective.

🗡️ The Burwell–Spiller Ridge

The ridge between Burwell and Spiller gives a preview of the increasingly technical terrain farther north.

Some climbers describe a short knife-edge feature and Class 3 scrambling along portions of the connection.

Other sections are dominated by loose scree and rubble.

The route is therefore substantially more serious than Burwell’s standard southeast ridge.

Anyone considering the traverse should already be comfortable with exposed scrambling, unstable rock, and route-finding.

🏔️ Looking Toward Babcock Peak

Babcock Peak towers beyond Spiller.

Its multiple summit points and notoriously rugged ridges create one of the most distinctive skylines in the La Plata Mountains.

Burwell’s lower elevation provides an excellent angle for studying the Babcock complex from the south.

The summit also gives climbers a clear appreciation for The Knife, the exposed ridge connecting Spiller with West Babcock.

The terrain becomes progressively more technical as the ridge moves north from Burwell toward the major thirteeners.

🏔️ Burwell Peak and Hesperus Mountain

Hesperus Mountain is the dominant peak of the entire La Plata Mountains.

Its summit rises to approximately 13,238 feet, only about 565 feet higher than Burwell.

Yet the difference in prominence is enormous.

Burwell has roughly 156 feet of prominence.

Hesperus has approximately 2,844 feet.

This comparison illustrates perfectly why elevation and topographic prominence measure very different characteristics of a mountain.

🐿️ Wildlife

The La Plata Mountains support a variety of Rocky Mountain wildlife.

Pikas inhabit rocky talus fields, while yellow-bellied marmots use alpine slopes and meadows.

Elk and mule deer are common in lower forest and open country.

Black bears inhabit wooded portions of the range, along with mountain lions, coyotes, foxes, and numerous smaller mammals.

Golden eagles and other raptors may occasionally be seen above the ridges.

Wildlife should always be observed from a respectful distance.

🌩️ Summer Thunderstorms

Lightning is one of the greatest hazards on Burwell Peak.

Colorado’s high mountains commonly experience afternoon thunderstorms during July and August.

Once hikers leave the forest and begin climbing the southeast ridge, shelter becomes increasingly limited.

Storms may bring:

Lightning
Hail
Heavy rain
Strong winds
Sudden temperature drops
Reduced visibility

An early start is strongly recommended.

Because much of the route is off trail, poor visibility can also make the descent significantly more confusing.

❄️ Snow Conditions

Snow can linger in the Boren Creek high country into summer.

Early-season travel may involve snowfields across steep slopes or gullies.

Depending on conditions, snow can occasionally make loose scree easier to cross, but firm snow can introduce dangerous fall potential.

An ice axe and traction may be appropriate during some early-season conditions.

Later in summer, snow generally retreats and loose rock becomes the greater concern.

🍂 Best Time to Climb

July through September generally offers the most practical climbing conditions.

July

Wildflowers can be excellent, although lingering snow may remain.

August

The route is usually more snow-free, but afternoon thunderstorms are common.

September

Cooler temperatures and reduced thunderstorm activity often produce excellent mountain conditions.

Early snowstorms can still arrive suddenly.

At nearly 12,700 feet, Burwell Peak can experience freezing temperatures during any month of the year.

🎒 What to Bring

Burwell Peak requires preparation for steep, off-trail mountain travel.

Useful equipment includes:

Sturdy hiking boots
Offline GPS mapping
Paper USGS topographic map
Compass
Plenty of drinking water
Water-treatment equipment
Warm layers
Waterproof shell
Sun protection
Gloves
First-aid kit
Headlamp
Emergency food
Satellite communicator

A helmet becomes increasingly worthwhile if continuing toward Spiller Peak because of the loose rock and Class 3 terrain.

🫁 High-Altitude Considerations

Burwell Peak rises above 12,600 feet.

Although lower than the neighboring thirteeners, the summit is still high enough for altitude to affect hikers arriving from lower elevations.

Symptoms may include:

Headache
Fatigue
Dizziness
Nausea
Unusual shortness of breath

Acclimatizing before the climb can help.

The route also gains roughly 3,500 vertical feet from the lower starting point, so maintaining a sustainable pace is important.

⚠️ Who Should Climb Burwell Peak?

Burwell is best suited to hikers who are already comfortable with:

Off-trail navigation
Loose talus and scree
Steep slopes
Class 2+ scrambling
Mild exposure
High-altitude hiking
Remote terrain

It is considerably less technical than Babcock Peak or the Babcock–Spiller Knife, but it should not be confused with a maintained trail hike.

For someone developing La Plata scrambling experience, Burwell can provide a useful intermediate objective before tackling the range’s more technical thirteeners.

🌟 Why Burwell Peak Is Worth Climbing

Burwell Peak is easy to overlook beside the giants of the La Plata Mountains.

It is lower than Spiller Peak, Babcock Peak, Mount Moss, Lavender Peak, and Hesperus Mountain. Its approximately 156 feet of prominence also leaves it well below Colorado’s threshold for a ranked summit.

On the ground, however, Burwell feels anything but insignificant.

The climb gains around 3,500 feet from La Plata Canyon, leaves maintained roads and trails behind, ascends steep loose slopes, and finishes on a rugged summit ridge overlooking one of the wildest collections of peaks in southwestern Colorado.

Its position on the southern rim of Boren Creek Basin provides a particularly good perspective on Spiller Peak, Babcock Peak, the Knife, and the higher La Plata skyline.

For hikers who value quiet summits, route-finding, geology, and challenging terrain more than official peak rankings, Burwell Peak is an excellent lesser-known destination in the San Juan Mountains.
