Pines

the sunlight pour onto his face like warm water. At this elevation, it was wonderfully concentrated.
    There was the smell of the dried pine needles baking in the sun.
    The sweet cold water.
    The bright sound of the river tumbling down through the canyon.
    The clatter of stones shifting under the current.
    The piercing blue of the sky.
    To be warm again lifted his spirits, and to be in the wilderness, despite everything, spoke to something buried deep in the pit of his soul.
    Last night, he’d been too tired to do anything but lie motionless on the stone.
    Now, his hunger returned.
    He fished the carrots and squashed bread loaf out of his pockets.

    Back on his feet, he scavenged until he found a pine branch in the nearby grove and broke off one end so that its length suited him for a walking stick. Spent several minutes stretching, trying to work the debilitating soreness out of his muscles, but it was a losing battle.
    He finally struck off up the canyon at a pace he thought he could maintain, but after ten minutes, the trauma of yesterday’s exertion forced him to slow down.
    A half mile felt like five.
    With every step, he was relying more and more on his walking stick for support, clinging to it like a lifeline, like his only decent leg.

    By early afternoon, the nature of the canyon had begun to change, the river narrowing until it could only be called a stream, pines shrinking, growing fewer and farther between, and those he encountered were stunted and gnarled, dwarfed victims of punishing winters.
    He was having to stop frequently, now resting more than he was walking, and constantly out of breath, his lungs burning with oxygen deprivation the higher he climbed.
    * * *
    Near dusk, he lay sprawled across a lichen-covered rock beside what was left of the river—a six-foot-wide, fast-moving current that babbled over a bed of colorful stones.
    It had been four or five hours since he’d left the alcove, and already the sun was sliding behind the canyon wall on the other side of the stream.
    When it disappeared, the temperature plummeted.
    He lay there watching the color drain from the sky, curled up against the coming chill, and the grim realization setting in that he wasn’t going to be getting back up.
    Turning over onto his side, he tugged the hood over his face.
    Shut his eyes.
    He was cold, but his clothes were dry, and he was trying to sort through a swarm of thoughts and competing emotions, the exhaustion pushing him toward the edge of delirium, and then suddenly he felt the sun beating down on his hood.
    He opened his eyes, sat up.
    He was still on that rock beside the stream, only now it was morning, the sun just peeking over the canyon wall at his back.
    I slept all night.
    He dragged himself over to the stream and drank, the water so cold it made his head ache.
    He had a carrot and a few bites of bread, and then struggled onto his feet and took a leak. He felt surprisingly better, the pain in his legs less all-consuming. Almost manageable.
    He grabbed his walking stick.
    * * *
    The canyon walls closed in and the stream dwindled into a trickle before finally disappearing altogether into the spring from which it sourced.
    In the absence of running water, the silence was blaring.
    Nothing but the clink of rocks under his boots.
    The lonely croak of a bird passing overhead.
    His own panting.
    The walls on either side of him were becoming steeper, and there were no more trees or even shrubs.
    Just shattered rock and lichen and sky.

    By midday, Ethan had abandoned his walking stick, reduced now to moving on all fours over the steepest terrain yet. As he worked his way around a bend in the canyon, a new sound crept in over the constant noise of shifting rocks. He leaned against a boulder the size of a compact car, trying to hone in on the noise over his own ragged breathing.
    There it was.
    Man-made.
    Steady.
    A low-decibel hum.
    Curiosity pulled him forward, Ethan climbing quickly until he’d cleared the corner, the hum becoming more prominent with every step, his anticipation spiking.
    When he finally saw it, a stab of exhilaration coursed through him.
    The canyon continued its steep ascent for another mile or two, the cliff walls topped with jagged spires and serrated ridges, an unforgiving cruelty to the landscape that looked almost alien.
    Fifty feet upslope, Ethan stared straight at the source of the hum—a twenty-foot-high fence crowned with coils of razor wire that spanned
