Schematic drawing of unit Eb4-2-200 excavated at Huari in 1977 by Dr. Isbell’s Huari Urban Prehistory Project. Initial excavation removed layers in a profile unit next to the road cut in order to expose and more clearly discern the layers that were then excavated in the 2-m x 2-m unit. The lowest levels contained a Huarpa occupation with architectural features, followed by early Huari occupation of Epoch 1A with further wall construction, then general occupational deposition into Middle Horizon Epoch 1B. The area within the 2-m x 2-m square above Stratum 14 was badly disturbed and therefore analysis continued with data collected from the profile square. Courtesy of Patricia J. Knobloch.
Profile of stratigraphy in the 1977 pipeline trench at Conchopata site. Drawn from field drawings by Perry Gnivecki. Units A and C were 2-m x 2-m excavations to bedrock. A group burial (not shown) was located between Unit A and the Offering Pit. Remnant walls at either end delimit a possible plaza with a pink sandy floor. Courtesy of Patricia J. Knobloch.
