Since 1984, Greg Deyermenjian and his team have been making scientific expeditions into the high and lower altitude jungle areas north and northeast of Cusco, Peru. Sponsored over the years by The Explorers Club; a Shipton-Tilman Grant from Gore Tex; and the Polartec Performance Challenge Award; the team welcomed its 2004 Expedition sponsor, Eastern Mountain Sports. Support from such prestigious sponsors is partly from the team's unquestionable reputation for scientific integrity and ethical conduct in both the execution and documentation of their findings- not to mention a passion beyond words.

"This expedition was the most ambitious and significant to date. We aimed to unearth new, historical evidence of the presence of the last Incas in this region- which we did- but more importantly, to assert that the quest for Paititi must continue- given the strategic location of these ruins along or near the Inca Road of Stone so far north." -G. Deyermenjian.


Cusco- direction Callanga
The team traveled by vehicle north of Cusco into the highland routes toward the jungles east in altitudes that exceed 4,000 meters. Documented ruins.

Return to Cusco
Returned to Cusco for fresh supplies. To conserve time and energy, the team hired a helicopter in Cusco to travel into the mountain jungle.

Inca Road of Stone and Lago de Angel
The helicopter dropped the team deep into the Pantiacolla area near the Lago de Angel. The team attempted to follow and map forgotten parts of the Inca Road of Stone up to an unexplored zone of the Pantiacolla Plateau- tracking important milestones at the Lago de Angel. Ruins and caves documented.

Following the trail down into the nearly impenetrable cloud-forest, and then climbing up to the highlands the team found the mysterious "8-shaped" lake that is now known as "Lago de Angel." The stonework of an ancient Incan presence around the lake seemed to continue on, ever northwestward.

Explore beyond Lago de Angel
GPS technology helped the team track their position along the way, while the wisdom and expertise of their Machiguenga guide, Goyo, would lead them toward the Rio Timpia.
At nearly 11,000 feet altitude, another platform of asymmetrical form, being shaped like a pointed bullet, with five sides, its tip pointed northeast. Its location offered a commanding view of two distinct river systems, that of the Yavero far below to the west, and that of the Timpia and its uppermost tributaries to the east.

Rio Timpia
They continued their journey around the headwaters of the Rio Ticumpinca toward the Rio Timpia, the furthest northern exploration yet. Slashing their way through thick, centuries-old vegetation, the team pushed ahead to an area where their most important ruins to date were found. Platforms discovered. Incan compound.

The location of the platform--at 12 degrees, 25.5 minutes south latitude, by 72 degrees, 11.5 minutes west longitude--mark it as the furthest Incan vestige to be found directly north of Cusco,
and the area as the furthest reach of the land mass which makes up the Meseta de Pantiacolla. And those dark ranges beyond constituted a blank space on the U.S. Department of Defense/ Peruvian Instituto Geografico Nacional's satellite-generated maps, an area labeled "DATOS INSUFICIENTES,"insufficient data, impenetrable as yet to the eye in the sky.

Lake of Suchi Cocha
These zones form a perimeter bearing strong evidence of Inca civilization, extending along the Paucartombo cordillera in the south toward the Toporake Plateau further north. Ruins found.
