GC16PH5 Aerial Intelligence - Marin 1 (Unknown Cache) in California, United States created by J5 Crew

J5 Crew: Unfortunately, I found the cache on the ground, open, and full of water today while on a Mount Burdell hike. After some contemplation, I decided to archive this oldie but goodie cache. It was a good, 17-year run. The ammo can final and first stage hide have been removed. Thanks to all who solved the puzzle and found the cache!

Geocache Description:

This is a puzzle cache. The cache is not at the posted coordinates! The final is located somewhere in Marin, but not at the posted coordinates, which would place you right in the middle of U.S. Highway 101. Please do not look for the cache at the posted coordinates!

This cache is inspired by several other “Aerial Intelligence” puzzle caches published in four other states: Nevada (GCGPYX), Virginia (GCM7J3 and GCHV7V), North Carolina (GCK1FA), and New Hampshire (GCXFT4). The first Aerial Intelligence cache was published in Nevada in February 2006, and I have borrowed some helpful photo interpreting comments from that listing for the benefit of seekers of this cache.

Interpreting aerial photographs requires some skill. People take years to become truly proficient at it. Some things to look for include roadways (look for number of lanes, width of road, and form), buildings (pay attention to size and shape), waterways, and other distinctive features. Your best bet is probably to have a map in one hand and the aerial photo in the other and switch back and forth between the two comparing features.

Below is an aerial photograph copied from Google Earth, which was taken above Marin County within the last five years. In the northwest corner of the picture, I have added a red arrow that points to where a magnetic key holder is hidden that contains the coordinates for the final. Your first goal is to identify the area in the aerial photograph and seek the magnetic key holder. When you find the key holder, please do not take the final coordinates from the key holder and please do not leave anything in the key holder. In order to claim the find, you must sign the logbook in the final. I recommend taking along a friend for a challenging and fun final retrieval.

Please do not post any pictures, measurements, or descriptions that would give away the actual location of the cache! Have fun and good luck!
