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.

Portal
Portal is a 2007 puzzle-platform game. Portal consists primarily of a series of puzzles that must be solved by teleporting the player's character and simple objects using the "Aperture Science Handheld Portal Device", also referred to as the "portal gun", a device that can create intra-dimensional portals between two flat planes. The physics system allows kinetic energy to be retained through portals, requiring creative use of portals to maneuver through the test chambers. Here is the trailer: Official trailer video
