Highland Mountains (Earth-5875)

The Highland Mountains were a huge group of mountain ranges in Viery, on Reach. They housed many military facilities of the UNSC, such as the Reach FLEETCOM Military Complex, Military Reservation 01478-B, Camp Hathcock, Castle Base, and Camp Indepence.

History
After the Fall of Reach, on August 30th, 2552, the Highland Mountains were the only parts in the entire colony that were not completely glassed by the Covenant. After the departure of the Fleet of Particular Justice, the remaining warships stood on the planet to excavate Menachite Mountain, which they discovered housed a forerunner reliquary thanks to a Luminary.
