Lavender Peak
Lavender Peak is a rugged 13,234-foot summit in the La Plata Mountains of southwestern Colorado, rising immediately east of Hesperus Mountain in San Juan National Forest. Although separated from Hesperus by barely half a mile, Lavender is a distinct ranked thirteener with approximately 374 feet of topographic prominence.
The mountain is particularly memorable for its unusual summit. Instead of a broad walk-up high point, Lavender culminates in a collection of blocky rock towers that require genuine scrambling to negotiate. The standard west-ridge approach is generally rated Class 3, with moderate exposure and the possibility of harder moves depending on route choice.
Lavender Peak also has an important place in Colorado mountaineering history. It was named for Dwight Garrigues Lavender, an influential young San Juan climber, writer, and explorer whose work helped document many of southwestern Colorado’s mountains during the early 20th century.

Modern LiDAR measurements place Lavender Peak at approximately 13,233.6 feet and give it about 374 feet of prominence. These measurements confirmed Lavender as a ranked Colorado thirteener and resolved a long-standing question about its relationship to neighboring Mount Moss.
🏔️ One of the Highest La Plata Mountains
Lavender Peak occupies the spectacular central cluster of the La Plata Mountains northwest of Durango.
Its closest neighbors include Hesperus Mountain, Mount Moss, Centennial Peak, Babcock Peak, Spiller Peak, and Sharkstooth Peak.
The highest summits of the range are packed remarkably close together:
- Hesperus Mountain — approximately 13,238 feet
- Lavender Peak — approximately 13,234 feet
- Mount Moss — approximately 13,193 feet
- Babcock Peak — approximately 13,160 feet
- Spiller Peak — approximately 13,134 feet
- Centennial Peak — approximately 13,068 feet
Lavender therefore misses being the range high point by only about four feet.
🧭 Nearest Higher Neighbor: Hesperus Mountain
Lavender Peak’s Nearest Higher Neighbor is Hesperus Mountain, immediately west-northwest of the summit.
Hesperus reaches approximately 13,238 feet, making it only about four feet higher than Lavender according to modern LiDAR measurements.
The two summits are separated by roughly half a mile, but the ridge connecting them is considerably more complicated than that short distance suggests. Loose talus, gullies, steep slopes, and rocky obstacles turn the traverse into a true mountaineering route rather than an easy ridge walk.
The tiny elevation difference between the two peaks also explains why the identity of the highest summit in the La Plata Mountains was once less certain than it is today.
📏 A Newly Confirmed Ranked Thirteener
Colorado peak baggers commonly use a minimum of 300 feet of prominence to determine whether a summit counts as an independently ranked peak.
Lavender Peak clears that threshold.
Current measurements give it approximately 374 feet of prominence, while nearby Mount Moss has only about 230 feet.
This was not always understood.
Older maps suggested a different relationship between the two peaks, and Mount Moss was historically treated as the ranked summit while Lavender was considered subsidiary.
Improved surveying and eventually LiDAR data reversed that interpretation. Lavender gained elevation relative to older mapping and was confirmed as the independent ranked summit, while Mount Moss became what Colorado peak baggers sometimes call an unranked or soft-ranked summit.
🪨 The Towers of Lavender Peak
Lavender Peak has one of the most unusual summit formations in the La Plata Mountains.
The upper mountain contains several closely spaced rock towers rather than a single simple summit mound.
Climbers approaching from the west encounter enormous stacked blocks and narrow passages as they work toward the highest towers.
Two of the western summit towers are extremely close in elevation, while a third point farther east is visibly lower.
Determining the precise natural high point can require climbing among the summit blocks rather than merely reaching the crest.
This unusual summit architecture is a large part of Lavender Peak’s appeal to experienced scramblers.
🧗 A Genuine Class 3 Summit
Lavender Peak is considerably more technical than neighboring Hesperus Mountain.
The standard west-ridge route is generally rated Class 3.
Climb13ers characterizes the summit terrain as boulder talus, rubble, and stacked blocks with moderate route-finding difficulty and short sections of moderate exposure.
Near the final summit towers, climbers must use their hands continuously in places.
Depending on the exact line chosen, some moves can approach Class 4. For that reason, other experienced climbers describe the peak as Class 3+.
Lavender is therefore best suited to hikers who already have experience on exposed Class 3 terrain rather than those making their first transition from ordinary hiking into scrambling.
🥾 The Standard West Ridge Route
The most frequently described approach reaches Lavender Peak from the west, usually after first climbing Hesperus Mountain.
From Hesperus, climbers descend southeast over loose talus and begin traversing toward Lavender.
The route passes several gullies and requires careful decisions about whether to remain near the ridge or contour across the southern slopes.
After reaching terrain below Lavender’s summit towers, climbers ascend a steep gully through increasingly large rock blocks.
The final scramble reaches the split high summit.
From Hesperus Mountain, the additional distance to Lavender is only around three-quarters of a mile one way, with roughly 400 feet of additional climbing.
The low mileage can be misleading. Loose terrain and Class 3 scrambling make the traverse considerably slower than an ordinary trail hike.
🥾 Starting From Sharkstooth Trailhead
The standard Hesperus–Lavender approach commonly begins at the Sharkstooth–Hesperus Trailhead, at an elevation of approximately 10,935 feet.
The trailhead is reached through San Juan National Forest from the Mancos side of the La Plata Mountains.
The final section of Forest Road 346 becomes increasingly rough, and high clearance is recommended. Four-wheel drive may not always be necessary in good conditions, but road conditions can change after storms, snowmelt, erosion, or maintenance.
From the trailhead, climbers initially follow the approach used for Hesperus Mountain before leaving established trail and climbing toward the high ridges.
🚙 Remote Road Access
Lavender Peak’s difficulty begins before the scrambling.
The drive into the Sharkstooth area travels deep into the La Plata Mountains over increasingly remote forest roads.
Drivers should be prepared for rough surfaces, sharp rocks, potholes, washouts, and seasonal mud.
A high-clearance vehicle is advisable for the final approach.
Useful vehicle equipment includes a full-size spare tire, tire-repair tools, extra drinking water, and enough fuel for unexpected delays.
Snow can linger on the higher roads well beyond the point when roads near Mancos are dry.
🏔️ Combining Hesperus and Lavender Peak
Most climbers pair Lavender Peak with Hesperus Mountain.
That combination makes geographic sense because Hesperus lies directly along the approach to Lavender.
Hesperus itself is generally easier, with a Class 2+ standard route. Once climbers leave its summit for Lavender, however, the character of the outing changes.
Loose ridge terrain, multiple gullies, large blocks, route-finding, and steeper scrambling begin to dominate.
Climbers should therefore evaluate the Lavender traverse separately rather than assuming that reaching Hesperus means they are automatically prepared for the neighboring summit.
🏔️ Adding Mount Moss
Mount Moss lies immediately southeast of Lavender Peak.
Strong climbers sometimes continue from Lavender to Mount Moss, creating a three-summit outing involving Hesperus, Lavender, and Moss.
The complete circuit can involve roughly 6 miles or more of travel and about 3,500 to 3,700 feet of accumulated elevation gain depending on the exact route.
The physical statistics tell only part of the story.
Much of the time is spent negotiating loose rock, route-finding, and exposed scrambling rather than walking established trail.
Combining all three peaks should therefore be considered a serious alpine day.
🪨 Geology of the La Plata Mountains
Lavender Peak belongs to one of Colorado’s most distinctive intrusive mountain complexes.
The La Plata Mountains were strongly shaped when magma forced its way into older sedimentary rocks millions of years ago.
Rather than simply erupting at the surface, much of this magma cooled underground as intrusive bodies.
The force of intrusion warped and uplifted overlying sedimentary layers, while heat altered some of the surrounding rock.
Subsequent erosion removed softer material and exposed the resistant mountain core.
This unusual geological history helps create the banded cliffs, towers, steep ridges, and enormous blocks characteristic of the Hesperus–Lavender–Mount Moss area.
🧱 Blocky Summit Geology
Lavender’s summit towers are particularly striking.
Large blocks appear almost stacked on top of one another, producing a summit environment that feels very different from a typical Colorado talus ridge.
The rock can be comparatively solid in some of the actual climbing sections, which makes the scrambling enjoyable for experienced climbers.
Elsewhere, however, loose rubble covers ledges and slopes.
The contrast between solid summit blocks and unstable surrounding talus means climbers must continually evaluate what they are stepping on or pulling against.
Testing holds before fully weighting them is a good habit throughout the upper mountain.
⛏️ Mining History
The La Plata Mountains have a long association with mining.
The name La Plata itself means “silver” in Spanish.
Gold, silver, copper, and other minerals attracted prospectors to the mountains during the late 19th and early 20th centuries.
Old mines, prospects, roads, ruins, and scattered pieces of mining equipment remain throughout portions of the range.
The region’s mineral wealth is closely related to the intrusive geology that helped build the mountains.
Hot mineral-bearing fluids moved through cracks and fractures around cooling magma bodies, depositing economically valuable ores.
Abandoned mine workings should never be entered because of unstable rock, hidden shafts, bad air, contaminated water, and deteriorated supports.
👤 Who Was Dwight Lavender?
Lavender Peak commemorates Dwight Garrigues Lavender, one of the most important early explorers of Colorado’s San Juan Mountains.
Lavender was born in Telluride in 1911 and developed an extraordinary interest in mountains while still young.
By his teenage years, he had become deeply involved in climbing and exploration across the San Juans.
He helped organize the San Juan Mountaineers, participated in dozens of first ascents, contributed mountaineering writing to several publications, and worked to improve mapping of poorly documented portions of the range.
🧗 Dwight Lavender’s Climbing Legacy
Lavender’s achievements were remarkable given his age.
The American Alpine Club later credited him with participating in more than 30 first ascents among a group responsible for more than 50 first ascents of 13,000-foot mountains in Colorado and Wyoming.
He was particularly fascinated by the Mount Sneffels region and worked on detailed surveys of peaks and pinnacles there.
Lavender also participated in the discovery, naming, and first ascent of El Diente and made the first ascent of Jagged Mountain.
His photographs and mountaineering albums from the late 1920s and early 1930s are preserved today by the University of Colorado Boulder Libraries.
📖 An Unfinished Mountaineering Career
Dwight Lavender died in 1934 at only 23 years old after contracting poliomyelitis while pursuing graduate studies in geology at Stanford University.
His death cut short a remarkable climbing and scientific career.
The American Alpine Club’s memorial described him as an authority on San Juan mountaineering even while still in his teens and early twenties.
Naming Lavender Peak for him provides an especially appropriate memorial.
The mountain bearing his name is not an easy walk-up summit. It demands the scrambling skills, mountain judgment, curiosity, and willingness to explore rugged terrain that defined Lavender’s own climbing career.
🌄 Views From Lavender Peak
The summit towers provide outstanding views across the La Plata Mountains.
Hesperus Mountain dominates the immediate western skyline.
Mount Moss rises only a short distance away, while Centennial Peak, Babcock Peak, Spiller Peak, and Sharkstooth Peak contribute to the surrounding maze of ridges.
Beyond the La Platas, the broader San Juan Mountains stretch toward the northeast.
Looking southwest, the high Rocky Mountain landscape gradually gives way to the mesas and plateaus of the Four Corners region.
Sunrise and sunset can transform the rocky ridges into shades of gold, orange, and purple.
🌲 Forests Below the Alpine Zone
The lower portions of the Lavender Peak approach pass through montane and subalpine forests.
Depending on elevation and exposure, vegetation can include:
- Engelmann spruce
- Subalpine fir
- Douglas-fir
- Ponderosa pine
- Quaking aspen
As climbers gain elevation, trees become progressively shorter and more scattered before disappearing near treeline.
The change from dense forest to open tundra also marks the point where exposure to weather increases dramatically.
🌼 Alpine Wildflowers
Summer wildflowers can be one of the unexpected highlights of the approach.
The lower slopes near Hesperus and Lavender are known for displays of Colorado blue columbine and other mountain flowers.
Depending on snowmelt and rainfall, visitors may also encounter paintbrush, lupine, asters, alpine sunflower, and cinquefoil.
The growing season is extremely short at these elevations.
Alpine plants may take many years to recover from damage, so hikers should travel on rock, gravel, existing paths, and other durable surfaces whenever practical.
🐿️ Wildlife
The La Plata Mountains support a variety of Rocky Mountain wildlife.
Marmots and pikas inhabit rocky alpine terrain, while elk and mule deer frequently use forests and high meadows.
Black bears occur at lower elevations, along with mountain lions, coyotes, foxes, and numerous smaller mammals.
Golden eagles and other raptors may occasionally be seen above the ridges.
Food should be stored securely when camping, and wildlife should always be observed from a distance.
🌩️ Summer Thunderstorms
Weather is one of the most important considerations on Lavender Peak.
Colorado’s summer monsoon frequently produces afternoon thunderstorms during July and August.
Lavender’s summit towers and connecting ridges offer essentially no meaningful protection from lightning.
Storms can bring lightning, hail, heavy rain, strong winds, and rapidly falling temperatures.
Because the technical portion of the climb takes time to reverse, climbers should start particularly early.
Being caught on the summit towers by an approaching thunderstorm would be a serious situation.
❄️ Snowfields
Snow frequently lingers in the gullies surrounding Lavender Peak well into summer.
Early-season conditions may dramatically change the difficulty of the traverse from Hesperus.
A gully that consists of loose rubble in August may contain hard, steep snow in June or early July.
Historical route descriptions specifically mention snow patches along the traverse.
Depending on conditions, an ice axe and appropriate traction may be necessary.
Climbers should evaluate actual mountain conditions rather than assuming that a route described as Class 3 in summer will remain Class 3 when snow-covered.
🍂 Best Time to Climb
July through September generally provides the most practical climbing season.
July can offer spectacular wildflowers, although snowfields may remain.
August usually brings more snow-free scrambling but also the greatest concern for afternoon thunderstorms.
September can provide crisp weather, clearer skies, and fewer thunderstorms.
Autumn arrives rapidly above 13,000 feet, however, and early snowstorms are possible.
Freezing temperatures can occur during any month.
🎒 What to Bring
Lavender Peak requires equipment appropriate for a genuine scrambling route.
Useful gear includes:
- Sturdy hiking boots
- Offline GPS mapping
- Paper topographic map
- Compass
- Plenty of water
- Food and emergency snacks
- Warm layers
- Waterproof shell
- Gloves
- Sun protection
- First-aid kit
- Headlamp
- Emergency communication device
A climbing helmet is worth serious consideration because of the loose terrain and potential for rockfall.
Depending on early-season snow, an ice axe and traction may also be appropriate.
🫁 High-Altitude Considerations
The Sharkstooth trailhead already sits around 10,935 feet, and Lavender Peak rises above 13,200 feet.
Hikers arriving directly from low elevations may feel the altitude immediately.
Symptoms can include headache, nausea, dizziness, unusual fatigue, poor appetite, and shortness of breath.
Acclimatizing before the climb can help.
More serious or worsening altitude symptoms are a reason to descend rather than continue upward.
The technical terrain near Lavender’s summit makes impaired judgment particularly dangerous.
🧗 Exposure and Scrambling Experience
Lavender Peak should not be chosen simply because its mileage looks short.
Class 3 climbing means hands are required for upward progress, and a fall in certain places could have serious consequences.
Climbers should already be comfortable with:
- Class 3 scrambling
- Moderate exposure
- Loose talus
- Route-finding
- Downclimbing
- Large boulders
- Moving efficiently above 13,000 feet
The ability to climb a move upward does not necessarily mean a climber will be comfortable reversing it.
That distinction matters on Lavender Peak.
🏔️ Lavender Peak vs. Hesperus Mountain
Hesperus Mountain and Lavender Peak are separated by only a few vertical feet but provide very different summit experiences.
Hesperus is the higher and vastly more prominent mountain.
Its standard west-ridge route is largely Class 2+.
Lavender, by contrast, has only around 374 feet of prominence but culminates in far more complicated Class 3 summit towers.
Hesperus is the major geographic mountain.
Lavender is the more technical scrambling objective.
Climbing both in one outing provides an excellent demonstration of how elevation, prominence, and climbing difficulty describe completely different aspects of a mountain.
🌟 Why Lavender Peak Stands Out
Lavender Peak is easy to overlook beside Hesperus Mountain.
It is slightly lower, far less prominent, and only about half a mile away.
Yet the summit has a personality entirely its own.
Modern LiDAR has confirmed Lavender as a ranked 13,234-foot peak. Its summit consists of dramatic rock towers requiring exposed Class 3 scrambling, and reaching those towers involves a rugged traverse through loose La Plata terrain.
Its name also preserves the legacy of Dwight Garrigues Lavender, whose brief but extraordinary mountaineering career helped document and explore the San Juan Mountains nearly a century ago.
For experienced Colorado peak baggers, Lavender Peak offers far more adventure than its modest prominence might suggest.
It is compact, rugged, historical, and technically engaging—a mountain where the final few hundred vertical feet are likely to be remembered far longer than the numbers in the summit table.
