Sixpac Manco Publications is an ongoing collection of books and monographs by architect, author and editor, Vincent R. Lee. Armed with an MFA in architecture from Princeton and following decades of drawing maps and house plans and climbing hundreds of summits as a part-time alpine mountain guide, in 1982 Vince embarked on yet another alternate career, in archaeological exploration.

Sixpac Manco I, his first expedition, took him to South America where he uncovered the forgotten remains of the Incas' final stronghold amongst the peaks and jungles of Vilcabamba, in the remote high Andes of Peru. In the years since numerous other trips (including Sixpac Manco XXIV at last count) have discovered, studied and documented the lost ruins of ancient New World civilizations from the American southwest, to Colombia, Ecuador and Bolivia. From the mysterious Chachapoyas "Cloud People" of northern Peru to the Inca metropolis at Espíritu Pampa, the "Plain of Ghosts" in the Amazonian rain forest, the many places he's worked, adventures encountered and lessons learned along the way are all recounted in the publications offered.

Prominent among these are accounts of Vince's many Vilcabamba expeditions over the years. They were done in partnership with the illustrious Cobos and Chavez families, long time residents and guides in the highland village of Huancacalle, a day's drive from Cuzco. Those with a yearning to follow Vince's exploits and see the marvelous sights of Vilcabamba for themselves will find clean friendly lodging at the Sixpac Manco Hospedaje near the trail head and top quality guides, gear and horses at
