On the night of August 11, 2552, Noble Team was stealthily deployed to the ridge to determine the extent of the Covenant's presence on Reach. They discovered that the Covenant fleet had created a landing site at the ridge.
The ridge spread over a long distance. On top of the ridge, there is a river which was used by a large hydroelectric power plant that provided energy for settlements throughout the territory. This upper river eventually fed into a river below the ridge. This larger, lower river fed into a large basin. There was a BXR Mine built into the ridge too.
