Go to the Posted Cache coordinates.
Step #1:
To get to Step #2:
For "N" coordinate, subtract 1527 from date the park area was first surveyed.
YYYY-1527 = N37º 20.NNN
(Put your answer here: Step #2 N37º 20.____)
For "W" coordinate, subtract 1427 from the date Second Street first bisected park.
YYYY-1427 = W121º 53.WWW
(Put your answer here: Step #2 W121º 53.____)
Step #2:
To Get to Step #3:
For "N" coordinate, subtract 1600 from date of McKinley's last Speech.
YYYY-1600 = N37º 20.NNN
(Step #3 N37º 20.____)
For "W" coordinate, subtract 1365 from the date this monument was erected.
YYYY-1365 = W121º 53.WWW
(Step #3 W121º 53.____)
Step #3:
To Get to Step #4:
For "N" coordinate, subtract 1591 from date this building was constructed. (Note the original dome this building once sported is missing, but can be seen in the historical drawings.)
YYYY-1591 = N37º 20.NNN
(Step #4 N37º 20.____)
For "W" coordinate, Add 271 to the street address of this building.
AAA+271 = W121º 53.WWW
(Step #4 W121º 53.____)
Step #4:
Step #4 is two part.
First Part:
The coordinates acquired in Step 3 will take you to a Brass Plaque. Use the Roman Numeral on the Brass Plaque and add 308 to get the N coordinate for the final cache.
XX+308 = N37º 20.XXX
(Cache is at N37º 20.____)
Second Part:
Go to the Memorial (“Kitty Corner” from the Brass Plaque) at:
N37º 20.304 W121º 53.430
Use the date Henry first settled in California and subtract 1429 for the “W” coordinate of the final cache.
YYYY-1429 = W121º 53.WWW
(Cache is at W121º 53.____)
Now find the Cache.

1. Corrected Coordinate for first Waypoint. 2. Adjusted difficulty rating as people were finding the cache despite the wrong coordinates
