The drive into town took less than five minutes. Chuck turned down Elkhorn Avenue, past the bookshop and knickknack stores, and parked in front of Estes Park’s public library, a sleek, stone-and-glass structure built on the banks of the Big Thompson River at the east edge of town. He pushed through the heavy glass front doors and headed for the research librarian’s desk at the back of the main floor.
Chuck had posted daily progress updates on the field school’s blog site throughout the summer, along with reports of the students’ upcoming work schedule. Anyone who knew of the vertical shaft’s existence and was following the updates would have known Team Nugget was set to uncover the shaft upon dismantling the last of the floor in the tunnel today.
What if someone hadn’t wanted the shaft uncovered, and had gotten hold of some blood to make the puddle, expecting that the anonymous report of it to the police would force Chuck to keep the students in town and away from the mine, at least for today, and perhaps for the remainder of the week? What might there be about the vertical shaft that, all these years later, was still worth keeping secret?
Chuck slowed to take in the view through the two-story wall of windows rising beyond the research desk. The Big Thompson River meandered past the back of the library through the heart of the flat, park-like valley from which the town of Estes Park derived its name. A mile farther east, the river entered V-walled Big Thompson Canyon and plunged, roiling, to the plains. Through the upper windows at the back of the library, Longs Peak, the 14,255-foot monarch of Rocky Mountain National Park, rose ten miles south of the Y of the Rockies complex, the mountain’s sheer east face, known as the Diamond, purple with afternoon shadow.
In the early 1900s, mountaineering guide Enos Mills summited the peak almost three hundred times as he led groups of flatlanders up the arduous route to the top of the mountain. Mills claimed the term “naturalist” for himself and devoted his life to a single cause: alerting an entire generation of Americans to the beauty and preservation value of the magnificent mountain wilderness seventy miles northwest of Colorado’s capital. His tireless work led directly to Congress’ 1915 pronouncement of the four-hundred-square-mile expanse of rivers, streams, high alpine meadows and jagged peaks directly west of Estes Park as the nation’s thirteenth national park, forever protected from human development.
The librarian seated at the research desk observed Chuck with twinkling eyes. She was well into her seventies, her mouth a bright red slash of lipstick beneath a powdered nose and rouged cheeks. A mauve blazer covered a silky white blouse fastened at the throat with an opal brooch. Her curled hair, dyed brunette, was shellacked into place. A cane fashioned from a gnarled tree branch leaned against her desk.
“Never grows tiresome,” the librarian said. Her voice was earthy and well-worn, almost masculine.
“You’ve got the best seat in town,” Chuck responded.
“That’s what they tell me every time I ask for a raise.”
Chuck glanced around. A middle-aged man read a magazine in an upholstered chair at the foot of the rear wall of windows. Several other easy chairs, aligned to take in the view of the river and Longs Peak beyond, were empty, and the aisles between the stacks of books leading away from the windows were deserted. The hordes of summer tourists in Estes Park obviously had more important things to do than visit the local library, and the locals were busy serving the visitors.
“I’d like to learn what I can about Cordero Mine,” Chuck told the librarian. “On Mount Landen, near Trail Ridge Road.”
The librarian crinkled her nose. “Cordero? Never heard of it.”
“You’re not alone. I’ve been assigned to do some archaeological work on it with a crew of college students. I spent some time in here a few weeks ago trying to do some preliminary research, but I couldn’t find a single mention of it.”
The librarian’s face lifted in a bewitched smile. “A mystery,” she said. “I like it.”
She took hold of her cane and pushed herself to her feet. She was under five feet tall, her shoulders bowed and misshapen. She limped heavily as she rounded her desk. A three-inch lift was glued to the sole of one of her brown, square-toed shoes to make up for a distinct difference in the length of her legs.
The librarian led Chuck down one of the aisles away from the wall of windows.
“Walk this way,” she told him. She wiggled her buttocks and gave a quiet snort of laughter as she shuffled down the aisle between the stacks of books, leaning on her cane.
They came to a row of computers lining an inner wall. The librarian took a seat in front of one of the machines and pulled a rolling chair from the next computer over for Chuck. Her knobby fingers danced across the keyboard in front of her.
Chuck watched the monitor over her shoulder as she worked her way from the Larimer County Records Department to the department’s mapping center to a bird’s-eye view of the Mummy Mountain Range. Controlling the computer’s mouse with nimble rolls and clicks, the librarian zeroed in on Mount Landen.
“Where is it?” she asked.
Chuck pointed at the east flank of the mountain, above tree line.
The librarian used the mouse to zoom in from above until the collapsed logs of the miners’ cabin became discernible in the grainy satellite photo.
With deft movements, she created a blinking, dotted-line box around the mine site, freed the boxed section from the satellite photo, and somehow transferred the freed section to another website, this one administered, as near as Chuck could tell, by an obscure branch of the U.S. Department of Mineralogy. There, the librarian pasted the box into a waiting screen, entered a series of coordinates in a search bar—numbers she’d memorized, apparently, from the Larimer County website—and clicked enter.
The Department of Mineralogy website popped up with a lengthy number of its own.
“Gotcha,” she proclaimed.
Before Chuck could say anything, the librarian sped on with her search, copying the number and moving to yet another website, this one operated by the State of Colorado. There she pasted the number into another search box and clicked the mouse.
This time there was a slight pause before the site displayed a few cryptic lines of text against a light-blue background:
Joshua Weed, Hiram Longstrom
Application No. 681, Claim No. 394
September 8, 1861
The librarian sat back from the computer and crossed her arms in front of her in satisfaction. She lifted a gnarled finger from the fold of her elbow and pointed at the screen. “No wonder you didn’t find anything. See the date?”
“A few months after the start of the Civil War, right?” Chuck asked.
“Yep. No wonder there’s no more information about it than this. The federal government had a few more important things to do than record and follow up on the last few mines being punched in the ground at the tail end of the Pikes Peak gold rush way out here in the middle of nowhere.”
“What about the name, Cordero?”
“Let’s take a look.” The librarian took command of the computer once more. Screenshot after screenshot flashed across the monitor as she worked. She pointed at the screen. “There. See?” A hand-rendered map of Rocky Mountain National Park glowed on the monitor. Fall River Road appeared as a curving line on the map, but Trail Ridge Road, opened in 1932, did not. And there, high on the east side of Mount Landen, as if by magic, was a black dot with the words “Cordero Mine.”
“Where’d that come from?” Chuck asked in surprise.
“Look at the lower right-hand corner,” the librarian said.
Chuck squinted, leaning forward. In the bottom corner of the map was an unintelligible signature. Below the signature, in careful, handwritten print, was the annotation:
Alfred Cordero, Lead Cartographer
Rocky Mountain National Park Cartographic Expedition
July-October, 1918
Chuck rubbed his chin with his finger. “You mean to tell me, some mapmaker decided to name an abandoned mine after himself?”
“It wasn’t uncommon. Expeditions across America in the 1700s and 1800s named geographic features after current politicians in hopes of securing funding for their next adventures. Expedition leaders and their cartographers almost always took advantage of the opportunity to name things after themselves along the way, too.”
“But a mine?”
“By the time the 1900s rolled around, pretty much everything was already named. I imagine Alfred Cordero couldn’t resist naming a piece of what was left for himself.”
“So he decided to stick his name on something somebody else had built.”
“Look where it’s located,” the librarian noted. “Dead center in the park. He put his name right in the middle of his map, where anybody and everybody would see it.”
“A mapmaker,” Chuck said, shaking his head.
She spun away from the computer to face him. “You sound disappointed.”
“I am.” He hesitated. The librarian’s blue-gray eyes gleamed with interest, prompting him to ask, “What’s your name?”
“Elaine. Elaine Bartholomew.”
“I appreciate your help, Elaine. I really do. But what you found was less than what I was looking for.”
“That much is obvious.”
He took a breath, let it out. “Something happened today,” he said. “Actually, a lot of things happened today. But the thing I’m trying to find out about…” He clicked his tongue off the roof of his mouth in frustration, started over. “What if I told you somebody worked really hard to hide something in that mine?” He pointed at the screen. “An entire vertical shaft, running straight down from a horizontal tunnel, perfectly overlaid with floorboards to make sure no one would know it was there.”
Elaine’s penciled eyebrows rose, deepening the wrinkles on her forehead.
“The Cassandra Treasure,” she said.
