Timeline

A Few Steps Back

• 2161: Fallout 1 begins.
• 2162: After The Vault Dweller destroys the Mariposa Military Base, he moves on to face the Master in the Vault under the Boneyard cathedral. It is unknown what has happened there, but due to the fact that the cathedral has not been blown up, it can be assumed that some unforeseen event happened. Later, Fallout 1 ends.
• 2220: Election of Richard "Dick" Richardson, the Enclave's leader, and the president of the USA. Enclave develops the Adv. Power Armor MKII.
• 2231: The Chosen One is born in Arroyo.
• 2235: Building of Gecko.
• 2236: An Enclave's scout finds the remains of the Mariposa Military Base. The excavation process begins, searching for the FEV. Frank Horrigan gets in contact with the virus and begins to mutate.
• 2237: The Enclave abandons the Mariposa Military Base, having obtained the FEV data, taking with it Frank Horrigan that is gradually mutating.

2238

• Harold arrives in Gecko, and (with a lot of shaking of his head) he does his best to help the ghouls with the running of the Nuclear Power Plant.
• NCR explorers discover Eagle Rock and quickly realize that it is a source of energy and some water -- albeit a dangerous source. Within the year, NCR miners are there, and more come shortly thereafter. Many of them are dregs/outcasts from other communities. The town of Burham Springs is established by Trent Burham, a wealthy NCR mine merchant.

Later on: 2239-2242

• 2241: Junktown becomes a part of the NCR state.
