Incident Description 

During construction of access tunnel L18-AT06, the construction crew encountered a basalt mass across the planned route. They received approval for a dogleg detour and rerouted the AT east for 3 meters with the intent of bypassing the obstruction. At 2.2 meters into the detour, they broke into an unexpected void, and ceased excavation to investigate the chamber.  

The revealed chamber extended 43 meters to the north, measured 27 meters at the widest point (east from the point of entry), and rose up to 15 meters high. There was no indication that water had permeated this far into the rock, leading the onsite Geo (Kat Edison B062) to suggest that the chamber was a planned excavation, though by who or what was unknown. 

Several unusual artifacts were recovered from the chamber. All were submitted to the research department. It was clear by their geometry and form that the artifacts were also constructed and not formed by natural process, though their purpose and origin was unknown. 

Actions taken after incident 

Artifacts and core samples sent to MLS Research Department. Floor 19 construction crew reassigned to Floor 16 duties. L18-AT06 has been designated as restricted access - Tier 3 and above.
