On a ceaselessly scenic rail line that flowed like a vein toward the heart of the Inca mountain empire, Kilometer Marker 104 did not look like anything special. There wasn't even an actual station there; just a ditch, where we stood all of 30 seconds before the train pulled away from us.
As we would do throughout our two days tramping around one of the world's most-photographed historic sites, Machu Picchu, we jumped when our guide Sebastian said jump.
A Quechuan native — essentially an Incan descendant — Sebastian somehow located my friends and me at sunrise that morning in a little lodge in the mountain town of Ollantaytambo, along a narrow street where no cars can go. He found us even while saying my name about as well as I pronounced Ollantaytambo.
Sebastian earned our trust again at our secluded train stop. He led us over the tracks to a rickety walking bridge across the Urubamba River, where we met up with the Inca Trail and our first ruins of the day, Chachabamba, a water temple cut into the hillside.
There, our short, smiley guide sat down with our group of five hikers and made an introductory confession that endeared him to us even further. Turned out, Sebastian wasn't entirely trustworthy.
"Only about 50 percent of what I'll tell you is probably true," he said.
After a few guffaws and a fake news joke he didn't seem to get, Sebastian explained himself. For all their fame and historic designations and National Geographic TV specials, our final destination of Machu Picchu and the surrounding Inca ruins sites are still being studied, still the subject of as many theories as facts.
The mountaintop ruins weren't even discovered by the Northern Hemisphere until 1911 — "discovered" a word Sebastian used with the same eye-roll as an American Indian on Columbus Day. Machu Picchu also didn't become a major tourist destination until earning UNESCO World Heritage Site status in 1983.
