Looking at a relief map of Alaska, you'd think the portion drained by the Copper River was so overweighted with mountains that it might topple the whole state into the Pacific. The Alaska Range, in the center of the state, has the tallest mountain, but this Gulf of Alaska region, straddling the Alaska-Yukon border, has more mass -- the second- and fourth-tallest mountains in North America (Logan and St. Elias), plus 9 of the tallest 16 peaks in the United States. Four mountain ranges intersect, creating a mad jumble of terrain covering tens of millions of acres, a trackless chaos of unnamed, unconquered peaks. The Copper River and its raging tributaries slice through it all, swallowing the gray melt of innumerable glaciers that flow from the largest ice field in North America. Everything here is the largest, most rugged, most remote; words quickly fall short of the measure. But where words fail, commerce gives a little help: These mountains are so numerous and remote that one guide service makes a business of taking visitors to mountains and valleys that no one has ever explored before.

Ironically for such a wild land, the area's main attraction for visitors is its history. The richest copper deposit in the world was found here in 1900 by a group of prospectors who mistook a green mountaintop for a patch of green grass where they could feed their horses. It was a mountain of almost pure copper, with metallic nuggets the size of desks (one is at the UA Museum of the North in Fairbanks). The deposit produced trainloads of 70% pure copper. The first ore was so rich it required no processing before shipping, then came lots more copper that did need minimal processing. Much more lower-grade ore still lies underground. The Alaska Syndicate, an investment group that included J. P. Morgan and Daniel Guggenheim, built the Kennecott Copper Corporation from this wealth (its name was a misspelling of the Kennicott River and Glacier, where the copper was found -- today, only the river and glacier go by the correct spelling). To get the copper out, they paid for an incredible 196-mile rail line up from Cordova and created a self-contained company town deep in the wilderness, called Kennecott. When the high-grade ore was gone, in 1938, they pulled the plug, leaving a ghost town of extraordinary beauty that still contains machinery and even documents they left behind.

Wrangell-St. Elias National Park and Preserve now owns Kennecott and more than 13 million acres across this region of Alaska. It's the largest national park in the United States by a long shot, six times the size of Yellowstone and about 25% larger than the entire country of Switzerland. The protected land continues across the border in Canada, in Kluane National Park, which is similarly massive. Most of that land is impossibly remote, but Wrangell-St. Elias has two rough gravel roads that allow access to see the mountains from a car. The main route is the abandoned roadbed of the Copper River and Northwestern Railroad leading to Kennecott and the historic sites there. It's an arduous but rewarding journey by car, requiring at least 2 days to do it right. Air taxis, river guides, and remote lodges offer other ways into the park's untouched wilderness, mostly starting from McCarthy, a historic village near Kennecott. There are a few trails near Kennecott, but only for dayhikes. This is a country where experienced outdoors people can get away from any trace of humans for weeks on end.
