A number of pukaras were encountered in the Block 3 area survey. Several of these [A03-607 and A03-796] include only small construction efforts on single walls, while a few pukaras had two or three defensive walls and structures on top, such as A03-1082. The most extensive evidence of pukara construction in Block 3 comes from A03-935, a large pukara on top of the lower sector of the Castillos de Callalli (the lower formation is also known as Cabeza de Leon) with natural escarpments over 50m high that were supplemented by four rows of walls on various areas of the hill. Three rows of walls were also encountered blocking access via the gullies close to Quelkata cave. This pukara represents a large, defensible zone.

Another relatively large pukara, Condorquiña [A02-6] was encountered in 2002 just over 5 km south along the west side of the Pulpera drainage (shown in Figure 6-69). Pukara Condorquiña has three major rows of walls and the remains of 10 oval structures on the summit the majority of them measuring about 1.8 x 2.3 m across.
