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. There are two award packages being offered: Silver and Gold. For the SILVER award, you must find at least 10 CASC geocaches in 3 counties. To qualify for the GOLD award, you must find at least 25 CASC geocaches in all 10 counties.

Space Invaders

Space Invaders was the first video game with endless gameplay and the first fixed shooter, setting the template for the genre. The goal is to defeat waves of descending aliens with a horizontally moving laser cannon to earn as many points as possible.  Space Invaders is considered one of the most influential and greatest video games ever.  It ushered in the golden age of arcade video games and keyed Japan's long-lasting global success in the video games industry. It inspired several prolific game designers to join the industry and influenced numerous games across different genres. 

This cache was hidden in preparation for Signal's Island.

 

Using the recommended access point, any vehicle can drive to this cache.
