Cache Across Southern California 2026
Greetings gamers! Are you ready to explore video games through the ages? Find and locate one of the roughly 50 CASC geocaches across all 10 Southern California counties. As you find geocaches, you may stamp your passport to track your progress and turn it in at Signal's Island in San Diego to redeem your prize(s)!
Do not remove the stamp from the container, it is part of this geocache!
How do I use the CASC Passport?
Use the stamp in each CASC geocache and stamp any of the 25 small game tokens on the front page of the passport. At the bottom of each coin, write the GC code of the geocache that corresponds to the stamp provided. Then on the reverse side, circle or highlight the caches you found from the list. Doing these steps will increase efficiency and line management at Signal's Island.
CASC Prize Redemption
To qualify for prize redemption you must bring your completed passport to Signal's Island Goes M*A*S*H (GCBGC72) in San Diego on Saturday, October 3rd 2026.

Fallout
Players step into the role of a survivor in a retro 1950s inspired post apocalyptic world filled with dark humor, eerie atmosphere, and classic music. As players explore ruins, vaults, and settlements, they gather supplies, uncover technology, and make choices that shape the future. The wasteland is ruled by mutants, machines, and powerful factions, and the player decides whether hope or ruin prevails.
After the Great War devastated America in a nuclear exchange, Vault-Tec built underground shelters to protect citizens while secretly conducting social experiments. Over time, survivors emerged to shape the wasteland across Fallout timelines, from Southern California in 2161 to West Virginia in 2102 and beyond.
Fallout is one of gaming’s most celebrated franchises, expanding across platforms and into a successful Amazon Prime series set in 2296.
Vault-Tec invites you to apply for residence in our underground vault community using the Kern County Vault 661 Application and Supply Box.
Sign the log and stamp your CASC Passport to formally submit your application.
This completes your request for Vault-Tec residency.
Applications will be reviewed during the next evaluation cycle.
VAULT-TEC REMINDS YOU:
Safety is mandatory. Obedience is happiness. Vault-Tec cares.
