Mount Drum

Mount Drum Over the Copper River | Jesse Campo

The Mount Drum–Sanford Plateau Route explores one of the wildest corners of Alaska’s Wrangell Mountains, beneath the enormous volcanic massifs of Mount Drum, Mount Sanford, and Mount Wrangell. Located within Wrangell–St. Elias National Park and Preserve, the area combines high alpine tundra, glacier-fed rivers, volcanic plateaus, moraine, snowfields, and almost complete isolation from roads and maintained trails.

One important distinction is worth making at the outset: the Sanford Plateau is best understood as a remote backcountry approach and trekking area near Mount Drum, not as one clearly defined official summit route up the mountain.

Documented Mount Drum climbs have instead used routes such as the North Ridge, North Glacier, and Southwest Ridge. The Sanford Plateau provides extraordinary access to the country around Drum and can form part of a larger expedition, but reaching Mount Drum’s 12,010-foot summit requires a separate technical mountaineering objective.

🗺️ Where Is the Sanford Plateau?

The Sanford Plateau occupies remote high country among some of the largest volcanoes of the Wrangell Mountains.

Mount Drum rises to the west, while the massive Mount Sanford dominates the northern and eastern skyline. Mount Wrangell and Mount Zanetti rise farther to the southeast.

There are no roads into this landscape.

Wrangell–St. Elias is enormous, and much of its interior remains genuine trail-free wilderness. Access to the Sanford Plateau commonly involves chartering a small aircraft from the Copper River Basin and landing at an appropriate backcountry location.

The exact landing area depends on terrain, snow, weather, aircraft type, and current conditions.

The wilderness experience begins almost as soon as the aircraft departs.

🧭 Is the Sanford Plateau Route a Mount Drum Summit Route?

Older route descriptions sometimes present the Sanford Plateau as though it were a standard established route to the summit of Mount Drum.

That description is somewhat misleading.

The plateau is closely associated with Mount Drum and provides excellent access to the broader area, but historical mountaineering accounts describe other climbing lines much more clearly.

Mount Drum’s 1954 first ascent was made by Heinrich Harrer, Keith Hart, and George Schaller via the North Ridge.

Later climbers approached from the Sanford River and used the glacier draining the north face before reaching higher snow and ice terrain.

The Southwest Ridge has also become an important modern mountaineering route.

For hikers and backpackers, the Sanford Plateau is best viewed as an exceptional wilderness destination in its own right.

For climbers, it may be part of the larger logistics of a Mount Drum expedition, but it should not be confused with a maintained or standardized summit trail.

✈️ Getting to the Route

There is no practical road approach to Mount Drum or the Sanford Plateau.

Mount Drum rises beyond the Copper River from Alaska’s highway network, and visitors generally rely on bush aircraft to reach suitable backcountry landing sites.

Gulkana is one of the principal aviation hubs serving this portion of Wrangell–St. Elias.

Fixed-wing aircraft are an important means of transportation throughout the park, where enormous distances and a lack of roads make aviation essential for many backcountry expeditions.

Exact drop-off and pickup locations depend on:

Aircraft type
Pilot experience
River conditions
Snow cover
Weather
Group size
Expedition objective

A landing or pickup location should never be assumed suitable simply because an earlier expedition used it.

Conditions can change from season to season.

🥾 The Sanford Plateau Backcountry Experience

Once dropped off, hikers normally have no maintained trail to follow.

Travel involves choosing a route through tundra, gravel, moraine, stream crossings, volcanic rock, and other natural terrain.

In places, the plateau can provide surprisingly open walking compared with the dense brush encountered in some Alaska valleys.

Alpine tundra and broad gravel benches can make travel relatively straightforward.

That does not make the trip easy.

Backpackers may still encounter:

Glacial rivers
Braided streams
Moraine
Wet tundra
Uneven volcanic rock
Snowfields
Poor visibility
Sudden weather changes
Long stretches without an obvious route

Commercial and private wilderness itineraries in the Sanford Plateau region may take several days despite relatively modest mileage.

Mileage alone is a poor measure of difficulty here.

Fifteen trail-free Alaska miles can require far more time and energy than the same distance on a maintained hiking trail.

🌋 A Volcanic Landscape

The Sanford Plateau lies within one of North America’s most remarkable volcanic regions.

The Wrangell Mountains were built through millions of years of volcanic activity.

Mount Drum is an extinct stratovolcano constructed from repeated eruptions of lava, volcanic breccia, ash, lahars, and other volcanic materials.

Late in its history, enormous explosive and gravitational events removed part of the volcano, particularly along its southern side.

Ancient volcanic avalanches and debris flows helped reshape the mountain into the rugged form visible today.

This volcanic history gives the Sanford Plateau region an unusual combination of:

Broad uplands
Eroded volcanic ridges
Lava-derived terrain
Glacier-carved valleys
Moraine
High snowfields
Massive isolated mountains

🏔️ Mount Drum

Mount Drum rises to 12,010 feet along the western side of the Wrangell Mountains.

Its elevation is impressive, but its local relief is even more striking.

The mountain rises thousands of feet almost directly above the Copper River Basin and can appear larger than some substantially higher peaks nearby.

Mount Drum has roughly 6,700 feet of topographic prominence, making it one of Alaska’s major independent mountains.

Its nearest higher neighbor is Ulu Point.

The mountain is especially distinctive because ancient volcanic collapse and later glacial erosion dramatically modified its southern slopes.

🧗 First Ascent of Mount Drum

Mount Drum was first climbed on June 4, 1954, by:

Heinrich Harrer
Keith Hart
George Schaller

The successful party used the North Ridge.

Harrer was already a highly accomplished mountaineer and later became widely known for Seven Years in Tibet.

George Schaller went on to become one of the world’s most influential wildlife biologists and conservationists.

Several earlier parties had attempted Mount Drum before the successful 1954 ascent.

The climb established the mountain as a serious Alaska mountaineering objective requiring much more than simple hiking ability.

🧗 The North Glacier Route

A documented 1975 expedition provides a useful picture of climbing Mount Drum from the north.

The climbers flew from Glennallen to a small landing area near the Sanford River north of Mount Drum.

From there, they traveled toward the glacier descending from the mountain’s north face.

Their route involved:

Approaching from the Sanford River
Reaching the north glacier
Establishing a high camp
Ascending the glacier
Reaching a high col
Climbing steep ice
Negotiating séracs and crevasses
Reaching the upper mountain and summit ridge

The account illustrates an important point about Mount Drum: even relatively direct routes involve serious glacier travel and alpine climbing.

🧗 Southwest Ridge

The Southwest Ridge is another important Mount Drum climbing route.

Modern climbing accounts describe a route involving steep snow, corniced ridges, technical climbing steps, and a long traverse across the broad upper summit terrain.

Potential challenges include:

Snow approaching 45 to 50 degrees
Cornices
Running belays
Technical steps
Downclimbing
False summits
Long exposed traverses

The route demonstrates why Mount Drum should not be regarded as a simple extension of a Sanford Plateau backpacking trip.

Reaching the summit remains a technical mountaineering objective.

🧊 Glaciers and Moraine

Glaciers are central to travel throughout this part of Wrangell–St. Elias.

Mount Drum, Mount Sanford, and surrounding volcanoes support numerous glaciers flowing into the valleys between them.

Some backcountry routes cross terrain containing debris-covered glacier ice, where rocks and sediment conceal the ice below.

This can produce difficult and unstable footing.

Potential glacier hazards include:

Open crevasses
Hidden crevasses
Collapsing ice
Meltwater channels
Snow bridges
Unstable moraine
Ice-covered streams

Travel directly on glaciers requires proper glacier equipment and crevasse-rescue skills.

🌊 Sanford River Crossings

River crossings can be among the most serious hazards in the Sanford Plateau region.

Glacial rivers change considerably throughout the day.

Warm temperatures increase meltwater, while heavy rainfall can raise water levels rapidly.

A braided stream that looks manageable in the morning may become much stronger by afternoon.

Potential hazards include:

Cold-water immersion
Strong current
Hidden holes
Slippery rocks
Shifting channels
Unstable gravel
Glacial sediment

Backcountry travelers should be prepared to wait, search for another crossing, or change plans rather than force a dangerous river crossing.

No itinerary is worth gambling against a powerful glacial stream.

🌿 Flora and Fauna

The Sanford Plateau lies largely above the dense boreal forests of the Copper River Basin.

Vegetation varies with elevation, exposure, and drainage.

Open plateau areas may support:

Alpine grasses
Sedges
Dwarf willow
Dwarf birch
Mountain avens
Heather
Mosses
Lichens
Low berry-producing shrubs

At lower elevations, vegetation transitions toward white spruce, black spruce, willow, alder, birch, and other plants characteristic of Interior Alaska.

The open terrain also provides habitat for a variety of wildlife.

Animals occurring in the broader area include:

Caribou
Dall sheep
Moose
Brown bears
Black bears
Wolves
Wolverines
Bison
Arctic ground squirrels
Ptarmigan
Golden eagles

The northern slopes around Mount Drum and Mount Sanford also provide habitat used by caribou.

🐻 Bear Country

Travelers should assume bears are present throughout the region.

Both brown bears and black bears occur within Wrangell–St. Elias.

Open tundra sometimes makes animals easier to spot at a distance than in dense forest, but surprise encounters can still occur around streambanks, ridges, gullies, or areas of taller vegetation.

Food and scented items should be stored according to current park recommendations.

Bear spray should remain immediately accessible rather than buried inside a backpack.

Groups should also avoid camping directly on obvious wildlife trails.

🌦️ Weather

Weather is one of the most unpredictable elements of a Sanford Plateau expedition.

Summer conditions can include:

Heavy rain
Strong wind
Fog
Snow
Sleet
Bright sun
Sudden temperature drops

Several of these conditions may occur during the same trip.

The enormous Wrangell volcanoes can influence local weather, and clouds may form rapidly around high terrain.

Poor weather also affects aircraft access.

A pickup flight may be delayed if visibility, wind, or landing conditions are unsuitable.

Backcountry travelers should therefore carry additional food and fuel rather than plan around a guaranteed extraction time.

🧭 Navigation

There are no maintained trails through most of the Sanford Plateau.

Strong navigation skills are essential.

Useful equipment includes:

Detailed topographic maps
Compass
GPS
Offline mapping
Spare batteries or power banks
Satellite communicator

Electronic navigation should never be the only option.

Fog can make broad plateau terrain surprisingly difficult to navigate, while river channels and glacier margins may change from what appears on older maps.

🛰️ Emergency Communication

Cell service should not be expected.

A satellite communicator or satellite phone is strongly recommended.

Backcountry travelers should also leave a detailed itinerary with someone outside the expedition.

That itinerary should include:

Planned route
Aircraft company
Drop-off location
Expected pickup area
Pickup date
Emergency contact information

Wrangell–St. Elias does not automatically begin a search simply because someone has failed to return on schedule.

Reliable outside communication is therefore extremely important.

🎒 What to Bring

A Sanford Plateau backpacking trip requires full wilderness equipment.

Typical gear includes:

Strong backcountry shelter
Warm sleeping bag
Insulated sleeping pad
Waterproof clothing
Warm layers
Sturdy boots
Trekking poles
Bear-resistant food storage
Bear spray
Water-treatment system
Navigation equipment
Satellite communicator
First-aid supplies
Repair kit
Extra food and fuel

Mountaineers attempting Mount Drum require an entirely different level of equipment.

Depending on the chosen route, that may include:

Crampons
Ice axes
Rope
Harnesses
Snow pickets
Crevasse-rescue equipment
Glacier travel gear
Technical climbing protection

The plateau backpacking journey and the summit climb should be treated as two very different levels of commitment.

📅 Best Time to Visit

The best season depends heavily on the goal of the expedition.

June

Snow may remain extensive, while lower elevations can already have active mosquitoes. River conditions vary according to snowmelt and temperature.

July

July provides extremely long daylight hours and often offers some of the best conditions for tundra backpacking.

August

Late summer brings cooler nights and early autumn color to the Wrangells.

Mountaineering Season

Technical Mount Drum expeditions may favor May through early summer, when snow and glacier conditions can be more consolidated.

There is no universally ideal period.

Conditions depend on:

Snowpack
River levels
Glacier conditions
Weather
Aircraft access
Route choice

🏞️ Wrangell–St. Elias National Park and Preserve

The Sanford Plateau lies within Wrangell–St. Elias National Park and Preserve, the largest unit in the U.S. National Park System.

The park covers more than 13 million acres and contains some of North America’s highest mountains and largest glaciers.

Unlike heavily developed national parks, Wrangell–St. Elias contains huge regions with no marked trails, bridges, campsites, or visitor facilities.

High peaks in the park are often heavily glaciated and can require technical expedition mountaineering.

Climbers without substantial experience in Alaska mountain environments should carefully evaluate whether professional guiding is appropriate.

🌋 Nearby Mountains

The Sanford Plateau occupies an extraordinary setting among several major Wrangell summits.

Mount Sanford

Mount Sanford rises to 16,237 feet and is one of the largest volcanic mountains in North America.

Mount Wrangell

Mount Wrangell reaches 14,163 feet and remains an active volcano.

Ulu Point

Ulu Point reaches 13,654 feet in the high terrain associated with Mount Sanford.

At 12,010 feet, Mount Drum is lower than several neighboring mountains but possesses enormous local relief and a dramatic profile above the Copper River Basin.

These peaks make the Sanford Plateau an exceptional place to experience giant Alaska volcanoes without necessarily climbing them.

🌄 Why Explore the Mount Drum–Sanford Plateau Area?

The Sanford Plateau offers something increasingly rare: a backcountry journey through a landscape largely without trails, roads, signs, bridges, or permanent recreational infrastructure.

The mountains surrounding it are enormous.

Mount Sanford rises above 16,000 feet. Mount Wrangell forms a vast ice-covered volcanic massif. Mount Drum towers over the western horizon, its rugged shape reflecting both ancient volcanic destruction and glacial erosion.

Yet portions of the plateau between these giants can provide surprisingly open tundra travel.

That contrast is what makes the area so compelling.

It is possible to backpack beneath some of North America’s largest volcanoes without attempting to climb them.

For experienced mountaineers who do want to attempt Mount Drum, the surrounding Sanford country also demonstrates that the summit is only one component of the expedition.

Access, glaciers, rivers, weather, navigation, wildlife, and isolation are all part of the challenge.

The Mount Drum–Sanford Plateau Route is therefore best understood not as a conventional trail to the summit, but as a gateway into one of Alaska’s great volcanic wilderness landscapes.
