Massive Australian Precambrian/Cambrian Impact Structure Massive Australian Precambrian/Cambrian Impact Structure The Massive Australian Precambrian/Cambrian Impact Structure also known as MAPCIS is a proposed impact structure based upon arguments presented by Daniel P. Connelly at Geological Society of America meetings. Its center is located approximately equidistant between Uluru (Ayers Rock) and Mount Conner in Australia's Northern Territory. The structure is approximately in diameter. However, a hypothetical outermost ring in diameter is claimed to be the result of undefined far field stresses. Connelly argues that the age of this hypothetical impact is approximately 545 mya which puts it just before the Cambrian explosion (542 mya) of the
Erebus haunted attraction these animatronics to bypass the “no-touch” safety rules, as well as other techniques such as dropping fake bugs from the ceiling, making building structures move. Erebus also uses landscape changes throughout the walk-through including inclines, stairwells, narrow passages, low ceilings and trap doors.

Unique in haunted attractions, Erebus has an illuminated scoreboard tracking "wimps" and "wetters".
