McCarthy Airport, the Glacier-Framed Strip at the End of the Road in Wrangell-St. Elias, and the Bush Pilots Who Keep Alaska's Most Remote Community Alive

McCarthy Airport (MCK) sits at the edge of one of the most isolated communities in North America, surrounded by glaciers and mountains that make it one of general aviation’s most striking destinations. For the 40 to 50 year-round residents of McCarthy, Alaska, the airport is not a convenience - it is the reason the town exists. When the road closes, the supplies, the mail, and the medevacs all move by air.

Where McCarthy Airport Is - and Why That Matters

McCarthy sits inside Wrangell-St. Elias National Park and Preserve, which covers over 13 million acres - the largest national park in the United States by a wide margin. It is larger than the entire country of Switzerland. The park occupies the southeast corner of Alaska, bounded by the Wrangell Mountains to the north and the St. Elias Mountains to the south.

The scale of the terrain is not easily conveyed on a sectional. The Bagley Icefield spans over 2,000 square miles. The Malaspina Glacier is larger than Rhode Island. The Kennicott Glacier runs over 25 miles down from the high country and is hundreds of feet thick in places - it frames the northeast approach into the McCarthy valley. The peaks overhead are not scenic background. Mount Blackburn and Mount Sanford each exceed 16,000 feet. Mount Wrangell, an active shield volcano, tops 14,000 feet. These are dominant terrain features with no forgiveness built in.

The Only Road In

There is exactly one road into McCarthy. The McCarthy Road runs 60 miles of gravel west from the town of Chitina, following an old railroad bed that has not been aggressively maintained. No gas stations. No guardrails in most places. In spring thaw, sections become impassable. The drive from Chitina takes two hours on a good day and sometimes doesn’t happen at all.

That road is the reason McCarthy runs on aviation. Not as a supplement - as infrastructure.

McCarthy Airport: Field Notes for Pilots

Identifier: MCK. Elevation: approximately 1,500 feet MSL. Runway: gravel, approximately 2,500 to 3,000 feet.

The runway is well-maintained by backcountry standards. It is honest: you will know when you’ve touched down on gravel. The approach from the west puts mountains on both sides and the Kennicott Glacier directly ahead - blue-white in summer sun, filling the windscreen as you descend into the valley. The red and white buildings of the old Kennecott mine complex are visible on the hillside above town to the right.

Density altitude is a year-round planning consideration. July temperatures can push density altitude well above 3,000 feet from a 1,500-foot field elevation. Aircraft arriving at MCK are typically loaded: hikers with full packs in summer, hunters with gear, game bags, and rifles in fall, outfitters moving seasonal supplies. Pilots flying this valley know their performance numbers on gravel and their weight and balance to the last pound - because the terrain around this valley does not accommodate errors.

Wildlife on the runway is a real checklist item. The procedure in Alaska is standard practice: fly a low pass, check for moose, check for bears, go around if needed, then land.

The Backcountry Pilot Culture Around Wrangell-St. Elias

The pilots working this region are bush pilots in the original sense. The Wrangell-St. Elias area has backcountry strips scattered across it - some Forest Service, some private outfitter strips, some gravel bars along rivers that someone determined were long enough and flat enough. The pilots who serve this region know all of them. They know which ones go soft when permafrost shifts in a warm July. Which ones have quirks on approach. Which ones require a specific departure procedure because of what is at the end of the runway.

The most critical skill in this environment is not stick-and-rudder technique. It is judgment about when not to go. A pilot with over 15 years working out of the Chitina area described it this way: when he was younger, he’d go around once and try again. Now he circles once, sees the valley weather isn’t cooperating, turns back to Chitina, and waits over coffee.

The valley has been there for 10,000 years. The pressure to press - schedules, waiting passengers, logistics - is real and constant. The ability to say no to that pressure and wait for the weather to decide what it wants to do is a skill. The backcountry has a way of building it.

The Kennecott Mines: Why the Town Exists

McCarthy does not make sense without the history above it.

Around 1900, prospectors working the Chitina River drainage discovered copper ore of extraordinary purity - one of the richest copper deposits ever found anywhere on earth. What followed was one of the most audacious engineering projects in Alaskan history. Kennecott Copper Corporation constructed the Copper River and Northwestern Railway - 296 miles of track running from the port of Cordova on the Gulf of Alaska to this valley. The line crossed the Miles Glacier and pushed through the Chitina River canyon over terrain that engineers said was unbuildable.

At the head of the deposit, the company built a 14-story ore processing mill directly against the hillside - still standing today in its original red and white. At peak operation, hundreds of workers lived in dormitories, used a company hospital, and worked shifts in a fully built-out industrial town accessible only by a train line that crossed two glaciers.

The mines operated for approximately three and a half decades. When the ore played out, Kennecott Copper Corporation locked the doors and walked away - left the machinery, the furniture, the food in the pantry. It was cheaper to abandon than to remove.

When Wrangell-St. Elias became a national park in 1978, the mines came with it. They are a National Historic Landmark today, and the National Park Service has been stabilizing the structures ever since. McCarthy is 5 miles down the road from Kennecott. The shuttle runs regularly. Standing under that mill building with a glacier rising behind it and nothing but wilderness in every direction is an experience that justifies the flight on its own.

What Summer Operations Look Like

Summer transforms McCarthy. The year-round population of 40 to 50 residents swells to several hundred on a busy July weekend. The lodges fill. MCK sees traffic it doesn’t see in December. Charter flights bring tourists from Anchorage for glacier walks and mine tours. Day-trip charters out of Chitina drop hikers in the morning and collect them in the evening.

The Root Glacier is accessible on foot from McCarthy. The Park Service has self-guided materials. But from the air, the glaciers reveal structure invisible from the ground: the medial moraines - dark stripes of rock running down the center of the glacier where tributary glaciers merged with the main flow - are readable from altitude. Each stripe is a different tributary. The glacial history is written in the ice.

Why McCarthy Matters to General Aviation

McCarthy is one of the cleaner statements about what general aviation actually is. The mail comes by air. Medical evacuations come by air. When the road closes and supplies need to move, they move by air. When outfitters need to get hunters to backcountry strips before first light in September, they go by air.

A community of 40 to 50 year-round residents chose a place with real winters, a road that might close for weeks, and a population that fits in a large living room. Aviation is what makes that choice sustainable. The pilots who serve it, season after season, without particular fanfare, are doing the foundational work the word “bush pilot” actually describes.

The Alaska Backcountry Pilots Association publishes resources worth reading before planning a trip to this region. The National Park Service has detailed materials on Wrangell-St. Elias and the Kennecott mines.
