The Grand Canyon

The grand canyon is a canyon located outside of the AEGAMI mineshaft. It was formed by a huge windstorm that passed the highway back in the nuclear war. The windstorm caused 10 deaths and 29 injuries in total. It used to connect the whole mineshaft to the entrance of roseweld. It used to have a big hallway that connects the sewer to the mineshaft. Everything got destroyed and only a big hole and a small part of the mineshaft was restored. Today, the mineshaft became a raider entrance, and connected with the sewers, eventually becoming a highly dangerous place for AEGIS Operatives. It's best that no one stays near the canyon, who knows if a second windstorm would strike again.
 
Today, the mine shaft is used as an illegal entrance to the Border. It leads to the caves above, which eventually leads into the roof. 
== The Breach (custom story) ==
During a short war with a minor raider faction, AEGIS began to notice that the raiders often came from the caves area. Despite this, AEGIS was sure of the integrity of the concrete wall closing off the mineshaft. AEGIS sent MDF Unit Hotel-22 to investigate what is now known as "The Breach". Hotel-22 discovered that the floor of the sewer passage running over the mineshaft was destroyed, and that raiders could freely drop down to avoid the much more noticeable method of blowing up the mineshaft wall.
As a consequence of this, AEGIS installed a motion detector near the entrance of the hallway, and also installed an observation platform with an elevator to further defend against the raiders.
