Emerald Cove

Emerald Cove was a UNSC colony world. During their training, the Spartan-II's were sent on an underwater mission with Chief Petty Officer Franklin Mendez. Mendez sabotaged half of the Spartans' air tanks and in return, they stole his. They then abandoned him and camped out on an island for a week, with nothing to do but light bonfires, bake clams, and surf, it was a good memory they all enjoyed sharing.

In 2542, the UNSC abandoned Emerald Cove due to the danger from the Covenant. Though there is no information in whether or not there was any combat in the abandonment and or evacuation, or if the planet was glassed or even located by the Covenant do to no Human presence
