In the morning, I drove to Pennsylvania, thirty miles or so to the north. The Appalachian Trail runs for 230 miles in a northeasterly arc across the state, like the broad end of a slice of pie. I never met a hiker with a good word to say about the trail in Pennsylvania. It is, as someone told a National Geographic reporter in 1987, the place “where boots go to die.” During the last ice age it experienced what geologists call a periglacial climate-a zone at the edge of an ice sheet characterized by frequent freeze-thaw cycles that fractured the rock. The result is mile upon mile of jagged, oddly angled slabs of stone strewn about in wobbly piles known to science as felsenmeer (literally, “sea of rocks”). These require constant attentiveness if you are not to twist an ankle or sprawl on your face-not a pleasant experience with fifty pounds of momentum on your back. Lots of people leave Pennsylvania limping and bruised. The state also has what are reputed to be the meanest rattlesnakes anywhere along the trail, and the most unreliable water sources, particularly in high summer. The really beautiful Appalachian ranges in Pennsylvania -Nittany and Jacks and Tussey-stand to the north and west. For various practical historical reasons, the AT goes nowhere near them. It traverses no notable eminences at all in Pennsylvania, offers no particularly memorable vistas, visits no national parks or forests, and overlooks the state’s considerable history. In consequence, the AT is essentially just the central part of a very long, taxing haul connecting the South and New England. It is little wonder that most people dislike it.

Oh, and it also has the very worst maps ever produced for hikers anywhere. The six sheets-maps is really much too strong a word for them-produced for Pennsylvania by a body called the Keystone Trails Association are small, monochrome, appallingly printed, inadequately keyed, and astoundingly vague-in short, useless: comically useless, heartbreakingly useless, dangerously useless. No one should be sent into a wilderness with maps this bad.

I had this brought home to me with a certain weep-inducing force as I stood in a parking lot in a place called Caledonia State Park looking at a section of map that was simply a blurred smear of whorls, like a poorly taken thumbprint. A single contour line was interrupted by a printed number in microscopic type. The number said either “ 1800” or “1200”-it wasn’t possible to tell-but it didn’t actually matter because there was no scale indicated anywhere, nothing to denote the height interval from one contour line to the next, or whether the packed bands of lines indicated a steep climb or precipitous descent. Not one single thing-not one single thing-within the entire park and for some miles around was inscribed. From where I stood, I could be fifty feet or two miles from the Appalachian Trail, in any direction. There was simply no telling.

Foolishly, I had not looked at these maps before setting off from home. I had packed in a hurry, simply noted that I had the correct set, and stuck them in my pack. I looked through them all now with a sense of dismay, as you might a series of compromising pictures of a loved one. I had known all along that I was never going to walk across Pennsylvania-I had neither the time nor the spirit for it just now-but I had thought I might find some nice circular walks that would give me something of the challenging flavor of the state without making me endlessly retrace my steps. It was clear now, looking through the complete set, that not only were there no circular hikes to be had, but it was going to be the next thing to pure luck any time I stumbled on the trail at all.

Sighing, I put the maps away and set off through the park on foot looking for the familiar white blazes of the AT. It was a pleasant park in a wooded valley, quite empty on this fine morning. I walked for perhaps an hour along a network of winding paths through trees and over wooden footbridges, but I failed to find the AT, so I returned to the car and pushed on, along a lonely highway through the dense flying leaves of Michaux State Forest and on to Pine Grove Furnace State Park, a large recreation area built around a nineteenth-century stone kiln, now a picturesque ruin, from which it takes its name. The park had snack huts, picnic tables, and a lake with a swimming area, but all were shut and there wasn’t a soul about. On the edge of the picnic area was a big dumpster with a sturdy metal lid that had been severely-arrestingly-mangled and dented and half wrenched from its hinges, presumably by a bear trying to get at park garbage. I examined it with the deepest respect; I hadn’t realized black bears were quite that strong.

Here at least the AT blazes were prominent. They led around the lake and up through steep woods to the summit of Piney Mountain, which wasn’t indicated on the map and isn’t really a mountain since it barely rises to 1,500 feet. Still, it was challenging enough on a hot summer’s day. Just outside the park there is a board marking the traditional, but entirely notional, midpoint of the Appalachian Trail, with 1,080.2 indicated miles of hiking in either direction. (Since no one can say exactly how long the AT is, the real midpoint could be anywhere within fifty miles or so; in any case, it would change from year to year because of reroutings.) Two-thirds of thru-hikers never see it anyway, because they have dropped out by this point. It must actually be quite a depressing moment-to have slogged through a mountainous wilderness for ten or eleven weeks and to realize that for all that effort you are still but halfway there.

It was also around here that one of the trail’s more notorious murders took place, the one at the heart of the book Eight Bullets, which I had bought at ATC headquarters the day before. The story is simply told. In May 1988, two young hikers, Rebecca Wight and Claudia Brenner, who also happened to be lesbians, excited the attention of a disturbed young man with a rifle, who shot them eight times from a distance as they made love in a leafy clearing beside the trail. Wight was killed. Brenner, seriously wounded, managed to stumble down the mountain to a road and was rescued by some passing teenagers in a pickup truck. The murderer was swiftly caught and convicted.

The next year, a young man and woman were killed by a drifter at a shelter just a few miles to the north, which rather gave Pennsylvania a bad reputation for a while, but then there were no murders anywhere along the AT for seven years until the recent deaths of the two young women in Shenandoah National Park. Their deaths brought the official murder toll to nine-quite a large number for any footpath, no matter how you look at it-though in fact there probably have been more. Between 1946 and 1950 three people vanished while hiking through one small area of Vermont, but they aren’t included in the tally; whether because it happened so long ago or because it was never conclusively proved they were murdered I couldn’t say. I was also told by an acquaintance in New England of an older couple who were killed by a deranged axe murderer in Maine sometime in the 1970s, but again it doesn’t appear in any records because, evidently, they were on a side trail when they were attacked.

Overnight I had read Eight Bullets, Brenner’s account of the murder of her friend, so I was generally acquainted with the circumstances, but I intentionally left the book in the car, as it seemed a little morbid to go looking for a death site nearly a decade after the event. I wasn’t remotely spooked by the murder, but even so I felt a vague, low-grade unease at being alone in a silent woods so far from home. I missed Katz, missed his puffing and bitching and unflappable fearlessness, hated the thought that I could sit waiting on a rock till the end of time and he would never come. The woods were in full chlorophyll-choked glory now, which made them seem even more pressing and secretive. Often, I couldn’t see five feet into the dense foliage on either side of the path. If I did happen on a bear, I would be quite helpless. No Katz would come along after a minute to smack it on the snout for me and say, “Jesus, Bryson, you cause me a lot of trouble.” No one at all would come to share the excitement, it appeared. There didn’t seem to be another person within fifty miles. I pushed on, filled with mild disquiet, feeling like someone swimming too far from shore.
