Dr. Thomas Ambrose may not have fit the stereotype of an eminent anthropologist, but he was one of the most respected people in the field. A professor emeritus at Arizona State University, he was an accomplished researcher, meticulous with written reports of his on-site investigations. Now in his late fifties- Pat guessed him to be ten years younger- he could boast of thirty years spent on the trail of early man and his cultures throughout the Southwest.

"Dr. Kidd was very mysterious over the phone. He offered almost no information at all about the discovery."

"And neither will I," said Ambrose. "It's best that you wait and see for yourself."

"How did you become involved with this find?" she asked.

"The right place at the right time. I was on a skiing vacation with an old girlfriend when I received a call from a colleague at the University of Colorado, asking if I'd take a look at the artifacts a miner reported finding. After a quick study of the site, I realized that I was in over my head."

"I find that hard to believe of a man with your reputation."

"Unfortunately, my area of expertise does not include epigraphy. And that's where you come in. The only one I know personally who specializes in deciphering ancient inscriptions is Dr. Jerry Kidd at Stanford. He wasn't available, but recommended you highly to take his place."

Ambrose turned, as the outside doors to the luggage drop were opened and the terminal ticket ladies who doubled as luggage handlers began throwing suitcases onto a sloping metal tray. "The big green one is mine," said Pat, thankful a man was there to tote her fifty-pound bag, which was packed with reference books.

Ambrose grunted but said nothing as he manhandled the heavy bag out to a jeep Cherokee that he'd parked in the lot outside the terminal. Pat hesitated, before entering the car, to absorb the magnificent view of the pine and aspen forests ascending the slopes of Mount Wilson and Sunshine Peak across the valley. As she stood enthralled with the panoramic scene, Ambrose took a moment to study her. Pat's hair was a radiant red and cascaded to her waist. Her eyes were a sage green. She stood as if sculptured by an artist, her weight on her right leg with her left knee turned slightly inward. Her shoulders and arms suggested a build more muscular than most women's, no doubt fashioned by long hours of exercise in a gym. Ambrose guessed her height at five feet eight inches, her weight at a solid 135 pounds. She was a pretty woman, not cute or strikingly beautiful, but he imagined she'd look very desirable when dressed in something more alluring than jeans and a mannish leather jacket.

Dr. Kidd claimed there was no better person than Patricia O'Connell to decipher ancient writings. He had faxed her history, and Ambrose was impressed. Thirty-five years old, with a doctorate in ancient languages from St. Andrews College in Scotland, she taught early linguistics at the University of Pennsylvania. Pat had written three well-received books on inscriptions she had deciphered on stones found in different parts of the world. Married and divorced from an attorney, she supported a young daughter of fourteen. A confirmed diffusionist, one who embraced the theory that cultures spread from one to another without being independently created, she firmly believed ancient seafarers had visited American shores many hundreds of years before Columbus.

"I've put you up at a nice bed-and-breakfast in town," said Ambrose. "If you wish, I can drop you off for an hour or so to freshen up."

"No, thank you," Pat said, smiling. "If you don't mind, I'd like to go straight to the site."

Ambrose nodded, took a cellular phone from a coat pocket, and dialed a number. "I'll let Luis Marquez, the owner of the mine, who made the discovery, know that we're coming."

They drove in silence through the heart of Telluride. Pat stared up at the ski slopes of Mountain Village to the south and saw skiers assaulting the steep moguls on the run that dropped to the edge of town. They passed old buildings that had been preserved over the past century, restored and now housing retail stores instead of a sea of saloons. Ambrose pointed to a building on his left. "That's the spot where Butch Cassidy robbed his first bank."

"Telluride must have a rich history."

"It does," replied Ambrose. "Right there in front of the Sheridan Hotel is where William Jennings Bryan gave his famous `cross of gold' speech. And farther up the South Fork Valley was the world's first generating plant, which produced alternating-current electricity for the mines. The plant's equipment was designed by Nikola Tesla."

Ambrose continued through the town of Telluride, busy with the invasion of skiers, and drove into the box canyon to where the paved road ended at Pandora. Pat stared in wonder at the steep cliffs surrounding the old mining town, taking in the beauty of Bridal Veil Falls, which was beginning to cascade with the runoff from the melting snow brought on by the prelude of a warm spring.

They came to a side road that led to the ruins of several old buildings. A van and a jeep painted a bright turquoise were parked outside. A pair of men were wearing wet suits and unloading what looked to Pat like diving equipment. "What can divers possibly be doing in the middle of the mountains of Colorado?" she asked vaguely.

"I stopped and talked to them yesterday," answered Ambrose. "They're a team from the National Underwater and Marine Agency."

"A long way from the sea, aren't they?"

"I was told they're exploring a complex system of ancient waterways that once drained the western flank of the San Juan Mountains. There is a maze of caverns that connect to the old mine tunnels."

Half a mile up the road, Ambrose passed a huge abandoned ore mill, where a large semitruck and trailer were parked beside the San Miguel River below the mouth of another old abandoned mine. Tents had been set up around the vehicles, and several men could be seen wandering about the camp. The sides of the big trailers were painted with words advertising the Geo Subterranean Science Corporation with home offices in Phoenix, Arizona.

"Another bunch of scientists," Ambrose volunteered without being asked. "A geophysical outfit, searching through the old mine shafts with fancy ground-penetrating equipment that is supposed to detect any veins of gold overlooked by the old miners."

"Think they'll find anything?" asked Pat.

Ambrose shrugged. "I doubt it. These mountains have been dug pretty deep."

A short distance later, Ambrose pulled to a stop in front of a picturesque little house and parked next to an old Chevy pickup truck. Marquez and his wife, Lisa, alerted to their coming, came out and greeted them, as Ambrose introduced them to Pat.

"I envy you," said Pat, "living amid such gorgeous scenery."

"Sad to say," said Lisa, "that after a year you don't notice it anymore."

"I don't think I could ever become immune to it."

"Can I get you folks anything? A cup of coffee? A beer?"

"I'm fine," answered Pat. "I would like to see your discovery as soon as it's convenient."

"No problem," said Marquez. "We still have five hours of daylight left. More than enough time for you to see the chamber and get back before dark."

"I'll have dinner waiting," said Lisa. "I thought you might like barbecued elk."

"Sounds wonderful," Pat said, already feeling the pangs of hunger.

Marquez nodded his head at the old truck. "You folks will have a more comfortable ride up to the mine if we take your jeep, Doc."
