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.

Marble Madness

Marble Madness is a 1984 platform game designed by Mark Cerny and published by Atari Games Inc. for arcades. Set in an isometric perspective, the game tasks the player with guiding a marble through six courses, populated with obstacles and enemies, within a time limit. The player controls the marble by using a trackball. Marble Madness is known for using innovative game technologies: it was Atari's first to use the Atari System 1 hardware, the first to be programmed in the C programming language and one of the first to use true stereo sound (previous games used either monaural sound or simulated sound).
Upon its release in arcades, Marble Madness was commercially successful and profitable. Critics praised the game's difficulty, unique visual design, and stereo soundtrack. The game was ported to numerous platforms and inspired the development of several similar games. A sequel was developed and planned for release in 1991, but was canceled when location testing showed it could not succeed in competition with other titles.

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