Puma Punku - Electronic Cavities
One of the more curious aspects of the many machined building blocks found at Puma Punku is the presence of routed shapes or cavities in the blocks. Some of these shapes are obviously inteded to be for metal cleats or staples that added reinforcement to the walls and structures of the site. However, others have no obvious use. Many perfectly routed cavity shapes exist where no cleating would be necessary or even possible to access after the blocks were connected to each other. Theories exist that suggest these shapes may have housed electronic devices that supplied lighting, controls or served other functions for the users and inhabitants of the site. One of these thories suggests a large platform and/or runway may have existed to service the takeoff and landing of flying crafts used by the extraterrestrial beings that built the site. This would explain the elaborate work done to create large expanses of smooth surfaces with reinforced walls, platforms and lighted pathways.
Above: A complex 4-level inset cavity cut into a stone block. Notice the geometric precision what would have been impossible without the use of a diamond-tipped CNC router used today. What type of device was this cavity created to hold? After 11,000 years, all remnants of metals, electronics or wiring would have decayed and blown away long ago, leaving only the routed granite shapes behind.
Below: The 2-level inset shape routed into the back of this cavity may have held a spring-loaded cleat or locking mechanism that allowed for something to be anchored into place or perhaps locked a mechanical or electrical device into position.
Above: Detail of an inset shap routed into the building blocks at Puma Punku. Notice the 3-levels of recessed depth that may have housed electronic devices providing light, control or other purposes unknown to us.
Below: Detail of more insets. Notice the left-facing arrow shape that may be pointing to the electronic device cavity on the far left. Or, it may have been pointing the correct direction to walk or land a flying vehical.
