He crouched back down and touched the water again. This time he held his fingers under the cold current. He didn't need a thermometer to know the temperature was in the forties. Too cold to bathe or swim comfortably. Since the dam was erected, it was always in the forties, forty-degrees Fahrenheit, plus or minus two, twenty-four hours a day, three hundred and sixty-five days a year. The temperature never changed at the bottom of a six hundred-foot dam.
One advantage of a colder river was that it benefited the rainbow trout introduced by the park service after the dam was completed. Rainbows love cold water, and the oxygen it carries. Unfortunately, the native humpback chub, which had lived in the Colorado for thousands of years, did not like it. Almost extinct now, the chub all but disappeared after the river turned cold, their exit accelerated by competition from the rainbows.
The man opened his pack. He gingerly moved the detonators and wires to the side, and reached for a clear Plexiglas container the size of a soda can. He uncapped it, and dipped it into the water. He recapped it and looked through it. Given some time, the silt would settle to the bottom, and he would be able to see exactly how much sediment was in the water.
He heard footsteps on the gravel behind, and he whirled to see two hikers, a man and a woman, approaching from upstream. He lunged to his pack, quickly covering the detonators, and almost dropped the water sample in the process. Had the hikers seen the detonators? He did not think so.
He studied their eyes to see if there were any signs that they had seen anything. The two did not look familiar, but that didn't mean they were not staying in the same campground. He had not talked to anyone. Leaving Las Vegas right after lunch the day before, he had driven straight to the North Rim, parked his truck, then made the long descent from the North Ridge via eight miles of winding trails to the river below, arriving in camp after dark. As the couple approached, the lady waved.
"Hi. It's a beautiful morning, isn't it?"
The skinny man stood and moved in front of his pack. He wiped his wet hand on his shorts and tried to think of a response. He didn't want a long discussion. "Yeah."
The woman's smile seemed to connect both ears. She had a few highlights of gray just visible under the straw hat. She and her male partner both wore khaki shorts and new hiking shoes, most likely purchased for this trip. The bearded man with her kept looking around at the canyon with his hand on his chin. He looked as if he would be more comfortable with a pipe in his mouth.
Neither the man nor the woman seemed particularly interested in his pack. Could that mean that they had not seen anything? Or were they just good actors?
The lady asked another question. "See any rafters on the river yet this morning?"
He looked across the river to avoid eye contact. "A couple."
"You're staying in our campground around the corner, aren't you?" She pointed upstream. "We saw you walk past our tent. You like to get going early, don't you? Where you from anyway? We're from Los Angeles. It's our first time in the Grand Canyon."
He wasn't sure which question to answer first. He hesitated then answered, "I like the peaceful mornings."
Maybe she was asking so many questions because she had in fact seen the detonators. What if these two were really undercover agents from some law enforcement agency? Or more likely, maybe they were just snoopy people who would report what they had seen to the first person they saw.
He quickly considered what to do. There was too much at stake to do nothing. What if he had to kill them? His knife was in the bottom of his pack and unreachable. He scanned the ground and saw multiple rocks the size of softballs. He looked up at the couple. The man was still gazing up the canyon walls. He was distracted. The woman seemed relaxed. What if he grabbed one of the rocks and bashed her in the head? That would do it. His hand twitched while he imagined her lying on the ground with a bloody crater on her head. He wondered if he would be able to get the man after the woman. The man's defenses would be up by then.
"What are you doing with that water?" She pointed at the plastic container of silty water in his hands. "You're not going to drink it, are you?" She stuck out her tongue in distaste. The woman made it hard not to look in her eyes, as if her eyes were hunting his.
He realized suddenly that these two had not seen the detonators. They were not a threat, and he would not need to kill them. They were just a couple of curious campers, happy to be in the Grand Canyon for the first time. Regardless, the encounter had made him nervous. He needed to move away from them and clear his head. He wondered how to end the conversation. "Well, I better go." He leaned down and zipped up the backpack, lifted it onto his shoulder, and walked past them. He held the water sample carefully in his hand.
She yelled after him. "Okay, we'll catch you later in camp or something."
From behind, the skinny man heard the man say to his wife, "I don't think he wanted to talk."
"Really? Why would you think that?"
He walked upstream around a bend in the river, away from the couple, away from people, until he was alone and could see a mile upstream. His heart was still beating fast. That had been too close, he had almost done something stupid, something that could have jeopardized everything he had worked so hard for. He had carried the detonators with him because he was too nervous to leave them in the truck, and that had almost screwed everything up.
He gazed upstream. He tried to picture the dam. He couldn't see it, of course; it was almost two hundred miles upstream. But he knew what it looked like. The Glen Canyon Dam rose over six hundred feet and completely blocked the canyon. It trapped Lake Powell behind it, with houseboats, water ski boats, and jet skis, all buzzing around like bees, with over three million visitors per year.
What he had never seen, unfortunately, were the canyons themselves, under all the water. Only about a thousand people ever had, before the dam buried them forever. He read accounts of people lucky enough to have explored them including John Wesley Powell himself. They declared Glen Canyon one of the most beautiful places on earth. They described pink undulating sandstone walls, some striped, with rain forest-like jungles in some of the side canyons, and green fractures high on the walls nourished by seeping springs. The endless carved rock canyons contained lush overhangs and rock amphitheaters. But now it was all gone, forever. It made his stomach tighten every time he thought about it.
Instinctively, he knew that it would be impossible to build the Glen Canyon Dam or most of the other fifty-three Colorado River dams today. Environmental impact studies would never allow them. Unlike in the early 20th century, modern politicians feared environmentalists.
But, even though the government had stopped building dams, and society had decided dams were detrimental to the environment, they left the big ones standing. Now built, the dams were forgotten. Even the environmentalist groups like the Sierra Club or GreenPeace didn't waste resources trying to get rid of the dams. There were too many other issues brighter on the radar.
Not that the man hadn't tried. Over the years, he had made his rounds in all the major environmental groups including the "Glen Canyon Institute," a group dedicated specifically to decommissioning the Glen Canyon Dam and restoring its canyons. But he finally realized the groups were all pissing into the wind. The issue didn't even register with today's politicians. Since lawyers had won most of the legislative seats in Washington and taken over the House and Senate like a virus, no risks were taken, no big decisions were made, good or bad. The bureaucracy was impenetrable. Decommissioning the Glen Canyon Dam was a fantasy.
