Highland Mountains

The Highland Mountains are a large range of alpine mountains located within the Viery Territory of the human colony, and UNSC fortress world Reach. Located on Reach's northernmost continent Eposz, the mountain range stretches many hundreds of kilometers, comprising thousands or tens of thousands of individual peaks. The Highland Mountains are mostly granite. Due to the area's remoteness, it was home to many UNSC facilities before the planet's glassing in 2552.

Human-Covenant war
After the Fall of Reach on August 30, 2552, these mountains were among the areas not heavily glassed by the Covenant, though glassing did occur in the area on a small scale. The Covenant concentrated their forces in the region and set up an extensive excavation operation around Menachite Mountain in order to uncover a massive subterranean Forerunner structure.

A flag was recovered from the mountains and put on display at Outpost Discovery.

Geography
Wild blueberry bushes and cedar trees grew in the mountains. East of the Highland Mountains is the Arany Basin.
