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. Silver award includes a small geocaching goodie bag, but Gold award includes a complimentary CASC 2026 geocoin + the silver award prize. Only one prize package per qualifying account. Prize distribution will be on a first come first served basis.

Monument Valley
Monument Valley is a 2014 Indie Mobile Puzzle Game created by Ustwo. The game centers around Princess Ida, who must be led through impossible objects and optical illusions to complete levels. Monument Valley has a heavy focus on sacred geometry and has a recognizable low poly minimalist art style.
At the posted coordinates you will find a certain character from Monument Valley, which you will use as a tool. Once you find the tool, make your way over to the "Log Location" waypoint, where you will use the tool to retrieve the log container with the stamp.
PLEASE RETURN THE TOOL BACK TO ITS ORIGINAL LOCATION WHEN DONE!!!
