<Department of Agriculture, Division 6>
Emergency call to all available Field Agents in the Area of Davis, CA.
You have been contacted because of your outstanding accomplishments in retrieving hidden objects. The Department of Agriculture, Division 6 - Extraterrestrial Activities - requests your assistance. To reject this mission leave this web-page immediately.

Thank you for your cooperation.
Mission details:
Division 6 has recently intercepted an alien communications signal. While the origin of the signal remains unknown, the content of the messages indicates that the intruders maintain a hidden communications outpost in the Area of Davis, CA.
Our cryptolinguists were able to extract detailed location information from one of the intercepted messages. The extracted coordinates, N38° 34.073' W-121° 40.551', are located in a cornfield close to the town. A thorough examination of the location by one of our response teams did not yield any results. We therefore need your help in order to increase the search radius into the residential areas without raising suspicion.
From previous encounters with alien intruders we know, that they sometimes encode coordinate offsets in crop circles around the target area. However, real-time satellite images have not shown any recent crop circle activity in the surrounding fields. We suspect that they have been covered up by local authorities conspiring with the intruders. We hope to employ your knowledge of the City of Davis to locate two concealed crop circles within the city limits. Based on our gathered data, we expect both of them to be located to the east of Pole Line Road. Please use the following Diagram to store the layout of the crop circles you found:
Once you have located the crop circles you will need to decode them in order to obtain the coordinate offset. Our cryptology specialists have been able to decode six circles with absolute certainty:
According to our specialists, only the quadrants of the radial lines (not the exact angle) are relevant in the alien number system.
Once you have obtained the final coordinates using the formulas given for Crop circle A and B, head to ground zero and locate the alien communications base. Approach carefully and try avoid any unnecessary attention.
Please note, due to recent budget cuts at our Department, we will not be able to offer you monetary compensation for participating in this mission. You will however get the chance to immortalize yourself as one of the finders of the alien outpost, should you be successful. Under certain restrictions you are also allowed to store and/or retrieve items from alien space vehicles. (The locking mechanism of alien spacecrafts usually use left-handed threaded screw caps).
Division 6 wishes you good luck on your mission.

Notes:
- This cache is the starting point for a geocoin of my good friends the "wandereulen" from Austria. I hope the FTF gives it a good start on its mission.
- The cache is 3d printed and fits the theme of this mission, it's a tribute to Yamar's great unusual cache series. Please handle it with care, the screw cap is using a left-handed thread due to an engineering mistake alien technology.
- It's my 90th cache and my first hide! (too bad i couldn't get the count up to 100 in time)
- This cache qualifies for the almost empty 34'/40' rectangle of the Every Minute in Davis challenge.
- Special thanks to my labmates for playtesting and to Beege49 and Papa EGTH for pointing out some description mistakes.
