Longhorn Valley
From Halopedia, the Halo wiki
Longhorn Valley was a geographical location in the Highland Mountains of the planet Reach.
Geography
It was a sloped region ten kilometers across, and contained a thick forest of Douglas firs, trampled fields, and the Big Horn River in the middle of it.
History
Before the Covenant invasion, the UNSC Army fireteam 3 Charlie on patrol in the valley.[1]
During the Battle of Reach, the valley was occupied by the Covenant, who built large defensive encampments in preparation for excavating the Forerunner complex beneath Menachite Mountain.[2] It was scorched with atomic fire after a team of Spartan-IIs destroyed a nearby Covenant Cruiser with a Fury Tactical Nuclear Weapon, and is presumed to have ultimately been glassed.
