This is a series of 7 total caches. 5 Arrow caches. 1 Beacon cache. And 1 mystery cache. The caches are placed very near all of the arrows and one beacon that are in Humboldt County. These arrows are located along the San Francisco to Salt Lake City route #18. This route was discontinued on November 30, 1930. I hope you enjoy finding these great historical structures and caches as much as I did placing them.
To locate the mystery cache you will need to find all of the 6 arrow and beacon caches and record the number that you find on the inside of the lid of each cache. You will need the numbers and what cache they were found at to get the coordinates for the mystery cache.
This arrow is in the worst condition out of all of the arrows in this series but still clearly visible. This one can also be driven right up to if the roads are dry.
