Mount Kilimanjaro

Located in Tanzania, near the border of Kenya, Mount Kilimanjaro is one of the Earth's most famous mountains, certainly the most famous African mountain. It is the tallest mountain in the African continent, and the tallest free-standing mountain in the world, at approximately 5,895 meters (19,341 feet), although it is actually a stratovolcano. Its name translates roughly from swahili into "White Hill."

In the 24th Century, meltwater from Kilimanjaro was collected by the Global Water Campaign water purification complex, processed, and sent along the GWC Trans-African Pipelines along the Tsavo Highway for use across the rest of the African continent. By the 26th Century this facility has fallen into disrepair and is overgrown in jungle after more than a century of neglect.

Spartan 117 crashed to Earth close to Kilimanjaro, with UNSC Marines assisting the Spartan in evading Covenant occupiers and clearing much of the jungle near Kilimanjaro of the Covenant presence before being extracted.

If a player gets 6 kills with in 4 seconds of each other, they get the medal "Killimonjaro." This has existed since Halo: CE, and provides further evidence that Bungie had, and always did have a plot ready for the entire Halo series.
