Los Angeles County Quadrangle Challenge Mystery Cache

The objective of this challenge is to find a cache in each of 81 USGS 7.5 minute topographical map quadrangles that cover Los Angeles County.

You MAY NOT take credit for finds made prior to the creation of the Los Angeles County Quadrangle Challenge (1 December 2006).

To complete this challenge and find the final cache, you must

1. Find a cache in each quadrangle shown in the attached grid.
2. Verify that you have completed the challenge by using the Checker at Project-GC.com here.
3. If you have any questions or problems, please contact me at craig.geocraig@gmail.com

A special thanks to mjp303 for the (GCYNR9) Bay Area Quadrangle Challenge which this cache was based on.

Lil Devil has created a Google Earth overlay of the quads.  It is quite useful in determining which quad a cache is located in.  The overlay is located here:  http://www.lildevil.org/download/GCZMBD-Los-Angeles-Quad-Challenge.kmz

If you would like a .gpx or .loc file of the quad corners, please let me know.  The color map was done in Streets & Trip '06.  If you would like that file, it is also available.

The guidelines:

• The posted coordinates are not the actual coordinates for the cache. The actual cache may actually be quite some distance from these coordinates!
• Generally accepted rules, guidelines and conditions for logging a cache find apply. These must be bona fide caches listed on Geocaching.com that you have personally (physically) found and logged.
• To level the playing field (and perhaps even handicap things for cachers who have many finds), you may not include caches found prior 1 December 2006.
• If you have found all the caches in a particular quadrangle, then you are allowed to revisit one of your previous finds to complete that quadrangle. Please bear in mind that the determination of whether or not you have visited all of the caches in a quadrangle will be as of the day you submit your cache list for verification.
• All cache types count as finds with the exception of events (CITO included) and locationless caches.
• For the purposes of this challenge, the coordinates listed on the cache page will determine which quadrangle puzzle and multi caches are located in, and not the coordinates of the actual physical cache.
• All caches found must be located in Los Angeles County.  For quads along the county boundaries, please pick a cache inside Los Angeles County.
• The boundary of each quadrangle in the challenge is determined by the coordinates listed on the USGS quadrangle map of the same name.
• If for any reason it becomes impossible to find a cache in a particular quadrangle, that quadrangle will be dropped from the challenge.
• While you may have others with you when you find the final cache, only those who have fulfilled ALL criteria for this cache will be allowed to log it as a find. 

Congratulations to Dooley and Ben for the co-FTF on the Challenge.  They completed all the requirements on Saturday, 1/6/07 and then found the final cache on Sunday, 1/7/07.

And congratulations to Journeymnn (and his son, J. Cacher) on making this cache his #1000 and for the first find since 7/07.
