Soil analysis confirms the Incas imported soil from different ecological regions of the empire to test specific plant species at Moray.
The temperature variation is so precise that the site recreates distinct vertical ecological tiers of the Andes in a single location.
The bottom of the deepest depression never collects water due to a complex system of natural and human-engineered drainage.
The concentric circles are perfectly circular, demonstrating advanced Inca geometric surveying capabilities.
Recent pollen analysis suggests the site was used to acclimate highland crops for lowland conditions and vice versa.
Moray consists of three major sinkhole-like depressions containing a series of concentric circular terraces. These terraces reach depths of up to 30 meters, with the largest circle measuring 220 meters in diameter. Archaeologists believe the site functioned as an agricultural laboratory where the Incas tested crop varieties in varying microclimates. The temperature difference between the top and bottom terraces can reach up to 15 degrees Celsius. Irrigation is managed through a sophisticated subterranean system that prevents flooding during heavy rainfall. The site's structural integrity remains despite the porous nature of the surrounding limestone bedrock. Each terrace level supports different ecological zones, allowing for the cultivation of diverse plant species from varying altitudes. The concentric design utilizes natural wind patterns to regulate temperatures at different depths.
The upper rim provides the only vantage point to capture the full, perfect concentric circular pattern of the largest depression.
Bring a windbreaker or layers, as temperatures drop significantly when descending to the lower terrace levels.
Walk the perimeter trail first to view the full scale of the circular depressions before descending.
Carry sun protection, as the high altitude and lack of shade increase UV exposure significantly.
Do not climb on the stone retaining walls, as they are fragile archaeological structures and strictly protected.
Stay strictly on marked paths to prevent soil erosion and structural damage to the ancient terraces.
