History
The SPARTAN-IIs used the Big Horn River for exercising under MCPO Franklin Mendez, which they eidetically knew.

During the Fall of Reach, the Covenant Fleet of Particular Justice sent a group of ten thousand troops to the region, accompanied by a CCS-class battlecruiser hovering Longhorn Valley. A section of the river and the battlecruiser were evaporated during the Fall when SPARTAN-IIs Fred-104, Kelly-087, and Joshua-029 destroyed the warship and its forces with a HAVOK tactical nuclear weapon.
