  "You want to record where the river outlet emerges into the Gulf."

  Duncan nodded. "That will give us an important hydrologic link."

  He was also going to ask if Pitt and Giordino might take water samples, but thought better of it. He had already pushed them as far as he dared. If they were successful in navigating the river as far as the hollow interior of Cerro el Capirote, then he and his fellow scientists could mount subsequent scientific expeditions based on the data acquired by Pitt and Giordino.

  Over the next ten minutes, Pitt and Giordino geared up and went over the plans for their journey. They had made countless dives together under a hundred different water and weather conditions, but none of this distance through the depths of the earth. Like doctors discussing a delicate brain operation, no detail was left to chance. Their survival depended on it.

  Communication signals were agreed upon, buddy breathing strategies in case of air loss, the drill for inflating and deflating the Wallowing Windbag, who was in control of what equipment-- all procedures were deliberated and jointly approved.

  "I see you're not wearing a pressurized dry suit," observed Sandecker as Pitt pulled on his wet suit.

  "The water temperature is a few degrees on the cool side, but warm enough so we don't have to worry about hypothermia. A wet suit gives us more freedom of movement than a dry suit that is pressurized by air tanks. This will prove a dire necessity if we find ourselves struggling in the water to right the Wallowing Windbag after it is flipped over by raging rapids."

  Instead of the standard backpack, Pitt attached his air tanks to a harness around his hips for easier access through narrow passages. He was also festooned with breathing regulators, air lines leading to dual valve manifolds, pressure gauges, and a small backup bottle filled with pure oxygen for decompression. Then came weight belts and buoyancy compensators.

  "No mixed gas?" queried Sandecker.

  "We'll breathe air," Pitt replied as he checked his regulators.

  "What about the danger of nitrogen narcosis?"

  "Once we're clear of the bottom of the sinkhole and the lower part of the feeder stream before it upslopes to the river, we'll avoid any further deep diving like the plague."

  "Just see that you stay well above the threshold," Sandecker warned him, "and don't go below thirty meters. And once you're afloat keep a sharp eye for submerged boulders."

  Those were the words the admiral spoke. What he didn't say was, "If something goes wrong and you need immediate help, you might as well be on the third ring of Saturn." In other words, there could be no rescue or evacuation.

  Pitt and Giordino made a final predive check of each other's equipment by the side of the pool and tested their ` quick-release buckles and snaps to ensure their smooth removal in an emergency. Instead of divers' hoods, they strapped construction workers' hardhats to their heads with dual-sealed miners' lamps on the front. Then they poised on the edge of the sinkhole and slipped into the water.

  Sandecker and Duncan hoisted a long, pressure-sealed aluminum canister and struggled to lower one end into the sinkhole. The canister, measuring one meter in width by four in length, was articulated in the middle for easier maneuvering through tight spaces. Heavy and cumbersome on land from the lead ballast required to give it neutral buoyancy, it was easily moved by a diver underwater.

  Giordino bit on his mouthpiece, adjusted his mask, and took hold of a handgrip on the forward end of the canister. He threw a final wave as he and the canister slowly sank together below the water surface. Pitt looked up from the water and shook hands with Duncan.

  "Whatever you do," Duncan warned him, "mind you don't let the current sweep you past the treasure chamber. From that position to where the river emerges into the Gulf has to be over a hundred kilometers."

  "Don't worry, we won't spend any more time down there than we have to."

  "May God dive with you," said Duncan.

  "All heavenly company will be warmly welcomed," said Pitt sincerely. Then he gripped Sandecker's hand. "Keep a tequila on ice for me, Admiral."

  "I wish there was another way into the mountain."

  Pitt shook his head. "It can only be done with a diveraft operation."

  "Bring Loren and Rudi back," replied Sandecker, fighting off a surge of emotion.

  "You'll see them soon," Pitt promised.

  And then he was gone.

  The voice of his radio operator roused Captain Juan Diego from his reverie, and he turned from gazing out his command tent at the cone-shaped mountain. There was an indescribable ugliness about Cerro el Capirote and the bleak desert that surrounded it, he thought. This was a wasteland compared to the beauty of his native state of Durango.

  "Yes, what is it, Sergeant?"

  The radio operator had his back to him and Diego couldn't see the puzzled look on the soldier's face. "I called the security posts for their hourly status reports and received no response from Posts Four and Six."

  Diego sighed. He didn't need unexpected predicaments. Colonel Campos had commanded him to set up a security perimeter around the mountain and he had followed orders. No reason was given, none was asked. Consumed with curiosity, Diego could only watch the helicopters arrive and depart and wonder what was going on up there.

  "Contact Corporal Francisco at Post Five and have him send a man to check Four and Six." Diego sat down at his field desk and duly noted the lack of response in his daily report as a probable breakdown in communications equipment. The possibility there was a real problem never entered his mind.

  "I can't raise Francisco at Post Five either," the radioman informed him.

  Diego finally turned. "Are you certain your equipment is working properly?"

  "Yes, Sir. The transmitter is sending and receiving perfectly."

  "Try Post One."

  The radioman adjusted his headphones and signaled the post. A few moments later, he turned and shrugged.

  "I'm sorry, Captain, Post One is silent too."

  "I'll see to this myself," Diego said irritably. He picked up a portable radio and headed from the tent toward his command vehicle. Suddenly, he stopped in his tracks and stared dumbly.

  The army command vehicle was sitting with the left front end jacked up, the wheel and the spare tire both nowhere to be seen. "What in hell is going on?" he muttered to himself. Is this some sort of prank, he wondered, or could Colonel Campos be testing him?

  He spun around on his heel and started for the tent but took only two steps. As if conjured up out of nothingness by a spell, three men blocked his way. All held rifles pointed at his chest. The first question that ran through his mind was why were Indians, dressed as if they were on a cattle drive, sabotaging his equipment?

  "This is a military zone," he blurted. "You are not permitted here."

  "Do as you're told, soldier boy," said Billy Yuma, "and none of your men will get hurt."

  Diego suddenly guessed what had happened to his security posts. And yet he was confused. There was no way a few Indians could capture forty trained soldiers without firing a shot. He addressed his words to Yuma, whom he took to be the leader.

  "Drop your weapons before my men arrive or you will be placed under military arrest."

  "I'm sorry to inform you, soldier boy," Yuma said, taking delight in intimidating the officer in his neatly pressed field uniform and brightly shined combat boots, "but your entire force has been disarmed and is now under guard."

  "Impossible!" snapped Diego haughtily. "No mob of sand rats can stand up against trained troops."

  Yuma shrugged indifferently and turned to one of the men beside him. "Fix the radio inside the tent so it won't work."

  "You're crazy. You can't destroy government property."

  "You have trespassed on our land," said Yuma in a low voice. "You have no authority here."

  "I order you to put those guns down," commanded Diego, reaching for his sidearm.

  Yuma stepped forward, his weathered face expressionless, and rammed the muzz
le of his old Winchester rifle deep into Captain Diego's stomach. "Do not resist us. If I pull the trigger, your body will silence the gunfire to those on the mountain."

  The sudden, jolting pain convinced Diego these men were not playing games. They knew the desert and could move through the terrain like ghosts. His orders were to prevent possible encroachment by wandering hunters or prospectors. Nothing was mentioned about an armed force of local Indians who lay in ambush. Slowly, he handed over his automatic pistol to one of Yuma's men, who stuffed the barrel down the waist of his denim pants.

  "Your radio too, please."

  Diego reluctantly passed over the radio. "Why are you doing this?" he asked. "Don't you know you are breaking the law?"

  "If you soldier boys are working with the men who are defiling our sacred mountain, it is you who are breaking the law, our law. Now, no more talk. You will come with us."

  In silence, Captain Diego and his radioman were escorted half a kilometer (a third of a mile) to a large overhanging rock protruding from the mountain. There, out of sight of anyone on the peak, Diego found his entire company of men sitting nervously in a tight group while several Indians covered them with their own weapons.

  They scrambled to their feet and came to attention, their faces reflecting relief at seeing their commanding officer. Two lieutenants and a sergeant came up and saluted.

  "Is there no one who escaped?" asked Diego.

  One of the lieutenants shook his head. "No, sir. They were on us before we could resist."

  Diego looked around at the Indians guarding his men. Including Yuma, he counted only sixteen. "Is this all of you?" he asked unbelievingly.

  Yuma nodded. "We did not need more."

  "What are you going to do with us?"

  "Nothing, soldier boy. My neighbors and I have been careful not to harm anyone. You and your men will enjoy a nice siesta for a few hours, and then you'll be free to leave our land."

  "And if we attempt to escape?"

  Yuma shrugged indifferently. "Then you will be shot. Something you should think about, since my people can hit a running rabbit at fifty meters."

  Yuma had said all he had to say. He turned his back on Captain Diego and began climbing an almost unrecognizable trail between a fissure on the south wall of the mountain. No words were spoken between the Montolos. As if on silent command, ten men followed Billy Yuma while five remained behind to guard the prisoners.

  The ascent went faster than the last time. He profited from his mistakes and ignored the wrong turns he had taken that curved into blind chutes. He remembered the good handholds and avoided the ones that were badly eroded. But it was still tough going on a trail no self-respecting pack mule would be caught dead on.

  He would have preferred more men to support his assault, but the ten men struggling behind him were the only ones who were not afraid of the mountain. Or that was what they claimed. Yuma was not blind to the apprehension in their eyes.

  After he reached a flat ledge, he stopped to catch his breath. His heart was beginning to pound, but his body was tensed with the nervous energy of a racehorse ready to burst from the gate. He pulled an old pocket watch from his pants pocket and checked the time. He nodded to himself in satisfaction and held the watch face for the others to see. They were twenty minutes ahead of schedule.

  High above, on the mountain's summit, the helicopters hovered like bees around a hive. They were loaded with I as much of the treasure as they could lift before struggling into the sky and setting a course for the airstrip in the Altar Desert.

  Colonel Campos's officers and men were working so fast, and were so awed by the golden hoard, none thought to check the security forces stationed around the base of the mountain. The radio operator on the peak was too busy coordinating the comings and goings of the helicopters to ask for a report from Captain Diego. No one took the time to look over the edge at the deserted encampment below. Nor did they notice the small band of men who were slowly climbing ever closer to the mountaintop.

  Police Comandante Cortina was not a man who missed much. As his police helicopter rose from Cerro el Capirote for the return trip to his headquarters, he stared down at the stone beast and caught something that was missed by all the others. A pragmatic man, he closed his eyes and put it off as a trick of sunlight and shadows, or perhaps the angle of his view. But when he refocused his eyes on the ancient sculpture, he could have sworn the vicious expression had altered. The menacing look was gone.

  To Cortina, just before it slipped out of view of his window, the fang-filled jaws on the guardian of the dead were frozen in a smile.

  Pitt felt as though he were free-falling down a mammoth soda straw filled with cobalt blue mist. The sides of the vertical shaft of the sinkhole were round and smooth, almost as if they had been polished. If he hadn't been able to see his diving partner through the transparent water a short distance below, the shaft would have seemed bottomless. He cleared his ears as he descended, finning easily until he caught up with Giordino, who was towing their dry transport container past the elbow bend at the bottom of the shaft. Pitt helped by pushing his end through, and then followed in its wake.

  He glanced at his depth-gauge needle. It was holding steady just shy of the 60-meter mark (197 feet). From here on, as the feeder stream sloped up toward the river, the water pressure would decrease, relieving any fear of depth blackout.

  This was nothing like the dive into the sacrificial pool on the jungled slopes of the Andes. There, he had used a strong safety line with communications equipment. And except for the brief foray into the side cavern to rescue Shannon and Miles, he was never out of sight of the surface. This trip, they'd be entering an underworld of perpetual blackness no man or animal had ever seen.

  As they moved their bulky canister through the twists and turns of the feeder stream leading to the river, Pitt recalled that cave diving is one of the most dangerous sports in the world. There was the Stygian blackness, the claustrophobic sensation of knowing you're far beneath the solid rock, the maddening silence, and the constant threat of disorientation if silt is stirred into impenetrable clouds. All this could lead to panic, which had killed scores of divers who were trained and equipped to deal with the perils, and made cave diving a morbid fascination that could not be learned from a book.

  What was it his instructor from the National Speleological Society had told him before his first dive into a saltwater cave in the Bahamas? "Anyone can die at any time on a cave dive." In that peculiar way a particular fact learned in youth can stick in your mind forever, Pitt remembered that during the year 1974, twenty-six divers had lost their lives in Florida's underwater caves alone, and that the world total of deaths must have been three times that figure.

  Pitt had never suffered from claustrophobia and fear seldom distracted him, but under hazardous conditions he experienced just enough uneasiness to sharpen his senses to unexpected dangers.

  As it was, he didn't look forward to diving without a fixed guide or safety line. He well knew this operation could quickly turn into an exercise in self-destruction, especially once they became uncontrollably caught up in the river's current. Then there would be no escape until they reached the treasure chamber.

  The horizontal fissure leading to the river expanded and tapered in a series of hourglass shapes. At 100 meters (328 feet) from the sinkhole they lost 90 percent of the outside light. They switched on the lamps attached to their hardhats. Another quick glance at his depth gauge told Pitt they had slowly ascended to within 20 meters (66 feet) of the water surface.

  Giordino ceased his forward movement, turned, and waved with one hand. They had reached the outlet into the river system. Pitt answered with the hand signal for OK. Then he slipped his arm through the strap attached to the transport canister so it wouldn't be torn from him by unforeseen turbulence.

  Giordino kicked his fins powerfully and angled upstream in a vigorous effort to pull the canister broadside into the river as far as possible before the main flo
w of the current swung him downstream before Pitt could exit the feeder stream. His timing was near perfect. Just as he lost his momentum and the current caught him in its grip, thrusting him around, Pitt and his end of the canister popped out of the side gallery.

  As previously planned, they calmly inflated their buoyancy compensators, released the lead weights on the canister to make it buoyant, and calmly drifted upward while being carried downriver. After traveling close to 50 meters (164 feet), they broke surface, their lights revealing a large open gallery. The ceiling was covered by a strange black rock that was not limestone. Only when Pitt steadied his light did he recognize it as volcanic. Fortunately, the river's flow was smooth and uninterrupted by rocks, but the walls of the passage rose steeply out of the water, offering them no place to land.

  He spit out his regulator mouthpiece and called to Giordino. "Be ready to cut to the side when you see an open spot on the bank."

  "Will do," Giordino said over his shoulder.

  They quickly passed from the volcanic intrusion back into limestone that was covered by an odd gray coating that absorbed their light beams and gave the impression the batteries were giving out on their lamps. A steady, thunderous sound grew and echoed through the passage. Their worst fears-- being swept through unnavigable rapids or going over a waterfall before making a landingsuddenly loomed in the darkness ahead.

  "Keep a tight grip," Giordino shouted. "It looks like we're in for a tumble."

  Pitt angled his head downward so the lights on his hardhat pointed directly to the front. It was a wasted motion. The passage was soon filled with a mist that rose out of the water like steam. Pitt had a sudden vision of going over Niagara Falls without a barrel. The roar was deafening now, magnified by the acoustics of the rocky cavern. And then Giordino passed into the mist and vanished.

  Pitt could only hold on to the canister and watch with strangely paralyzed fascination as he was enveloped by the spray. He braced himself for an endless fall. But the endless fall never came. The thunder came not from the river plunging downward, but from a furious torrent that crashed down from above.
