The high peaks off to the north were already swathed in clouds as solitary rainstorms paid court to mountaintops rarely reached by man. To the south, cloud shadows swept over land broken by canyons and rocky ridges. Random, isolated thundershowers showed as thick columns of gray that were embedded in the earth at one end and crowned by seething white billows on the other.

Even as Carla appreciated the splendor of rainbows glittering among the racing storm cells, she was relieved to see that none of the isolated thundershowers had ganged up and settled in anywhere for a good cry. She had driven dirt roads long enough to know that she didn’t want to drive through mud if she could help it. Nor was she enthusiastic about the idea of fording washes that were hub-deep in roiling water. Fortunately it was only a few more miles to Picture Wash, and from there it was just under three miles to the mouth of September Canyon. Even if she had to walk, she would have no trouble making it before sunset.

Smiling at the excitement she felt rising in herself at the knowledge that she was finally within reach of the canyon that had haunted her for seven years, Carla got back in her little pickup and drove down the road, trailing a modest plume of dust behind.

The dust Luke raised heading for September Canyon could in no way be called modest. A great rooster tail of grit and small pebbles boiled up in the wake of his full-size pickup truck. He drove hard and fast, but never dangerously. He knew each rut, pothole and outcropping of rock in the road. Close to the ranch house he drove between barbed wire fences marking off pastures. Farther from the house he came to the open grazing land.

There was no gate to the open area. There was only a cattle guard made of parallel rows of pipes sunk into the road at a right angle. The pipes were spaced so that a cow would shy back from walking on them for fear of getting a hoof caught in the open spaces between the bars. The cattle guard offered no deterrent to vehicles beyond the startling noise caused by tires rattling and clattering over pipes.

Luke occupied his mind with the condition of the road or the look of the cattle grazing nearby or the number and kind of plants growing in roadside ditches. The road needed grading. The fences could have used tightening in a few places. The cattle were sleek and serene, grazing in good forage or lying beneath scattered trees to ruminate. The roadside plants were lush with water from a recent storm that had raced by, grooming the land with a wet, lightning-spiked tongue.

More rain threatened. Luke had outrun one thunderstorm, dodged another by taking a shortcut and had plowed through a third. The clouds overhead suggested that evasive maneuvers wouldn’t work much longer. He assessed the state of the sky with an anger he didn’t examine and pushed harder on the accelerator, picking up speed. If it kept raining off to the southwest, water would be running in Picture Wash before sunset and Carla might become isolated on the other side. There were no other roads into September Canyon. The only trail was one he had discovered seven years before, when he had been combing the Rocking M’s most distant canyons on horseback, looking for strays. In good weather the trail was harsh enough; in bad weather it would be hell.

I’lltake the trail, if it comes to that. Carla shouldn’t be out there by herself.

Why not? asked a sardonic corner of Luke’s mind. She’s safer out there alone than she is with me and I damned well know it.

Surely I can keep my hands off her until Cash gets here.

Yeah, that’s what he was gambling on, wasn’t it? And that’s why I called him a fool.

Luke’s mouth flattened into a grim line as the truck began to descend in a long series of switchbacks that would eventually lead to the lower elevations where Rocking M cattle grazed in winter and cottonwoods grew year-round, shading sand-bottom creeks with massive elegance.

Usually the creeks ran clear, as transparent as the raindrops that had spawned them. But by the time Luke reached Picture Wash, the water was a churning swath of brown. He stopped the truck, got out and guessed the height of the water over the dirt road by how much of the streamside vegetation was underwater. There was no doubt that Carla had crossed here – the narrow tires of her baby pickup had left a trail right into the water. The fact that she hadn’t bogged down proved that she had crossed earlier, before Picture Wash had filled with runoff water. The stream was double its normal volume now but still could be forded by a vehicle with four-wheel drive, good axle clearance and a skilled driver. But if Luke had been an hour later, he would have spent the night camped on the wrong side of the wash.

Luke drove the truck through the muddy water and accelerated up the rise on the far side. A passing thunderstorm had dampened the road enough to show tracks clearly but not enough to make driving tricky. The sight of the tread marks left by Carla’s ridiculous pickup acted as both goad and lure to Luke. He didn’t even pause to look at the outcropping of smooth, rust-colored rock that had given the wash its name. Ancient tribes and not-so-ancient cowboys had inscribed their marks in ageless stone, leaving behind stylized pictographs or impenetrable scrawls.

The road bent off to the right, following the base of the cliffs that paralleled Picture Wash. A few miles farther up, the road turned off into one of the many side canyons that emptied into the wide, sandy wash. There was nothing to mark this canyon as different from any other except the new tire tracks overlying a vague hint of older tracks – that and a discreetly placed cairn of stones telling anyone who could read trail signs to turn left there.

It was barely half an hour to sundown when Luke drove up next to Carla’s toy pickup and parked. He got out, took one look at the sky and pulled on a knee-length yellow slicker that was slit up the back to permit riding a horse. Within moments he was headed for the spot where a bend in September Creek had undercut the stone cliff. The creek had long since changed course, cutting a new bed on the far side of the canyon, a hundred yards away and thirty feet lower in elevation. The ancient streambed was now high and dry, protected by an overhang of massive stone that shed rain in long silver veils. Beneath the overhang it was dry except for a single, moss-lined seep no bigger than a hat. The water from the seep was clean and cool and sweet, as heady to a thirsty hiker as wine.

Like the experienced camper she was, Carla had set everything out before she went exploring. Two sleeping bags were stretched over individual strips of foam mattress. A campfire was laid out, ready to ignite with a single match. Cooking gear and firewood were stacked nearby. Someone who came in cold, wet and tired could be comfortable within a few minutes.

Luke turned his back on the overhang and went looking for Carla. Beyond the protection of the slanting stone, her tracks showed clearly against the countless dimples raindrops had left in the dust. Even though her tracks were obvious, Carla had left a small pile of stones that indicated the direction she had taken. Luke followed quickly, knowing that she would mark any changes in direction by another pile of stones.

Ten minutes later he climbed up the shoulder of a tongue of land that poked out into September Canyon. From where he stood, he couldn’t see the overhang where Carla had set up camp, but he could see three miles down the creek itself to the point where it joined Picture Wash. The view was wild, untouched, unchanged since man had first come to walk the land thousands upon thousands of years ago. Indigo storm clouds seethed in slow motion, impaled on shafts of pure light thrown off by the setting sun. Red cliffs wept streams of silver tears, fragile waterfalls whose lifespan could be measured in hours. There was no wind, no rain, no sound but that of silence itself, an immensity that embraced sky and untamed land alike.

And watching it all was Carla, standing at die very edge of the rise, a smile on her lips and serenity in every line of her body.

Slowly Luke walked toward Carla, watching her watch the land, hungry for her in ways he couldn’t name, savoring the fact that she so obviously loved the untouched vista of stone and sunlight, silence and cloud. She had had every excuse in the world to drive into Boulder’s concrete excitements and enticements, but instead she had headed even deeper into the uninhabited land.

But only for a few days, Luke told himself savagely. Remember that. She just came here for a few days of vacation. That’s a hell of a long way from being able to take a lifetime of isolation. No woman wants that, and no man has the right to ask for that kind of sacrifice.

And no matter how beautiful the Rocking M might be, it was isolated. There was no doubt about it, no finessing it, no forgetting it.

"You’re damn lucky it’s me rather than some stranger following your tracks up here," Luke said roughly.

Carla spun around, her eyes wide with surprise. "Luke! My God, you scared me sneaking up like that!"

"Sneaking?" Luke looked at his cowboy boots.

"Schoolgirl, I couldn’t sneak up on a corpse wearing these."

"Maybe not, but you crept up on me just fine. What are you doing here?"

"You took the words right out of my mouth."

"I’m taking a vacation, just like I planned."

"Not quite," Luke said tightly. "Last I heard, Cash was still in Boulder."

"Only until the Jeep gets fixed."

"And meanwhile you expected me to let you stay out here alone?"
