This cache is a simple field puzzle that should be fun, educational, and most importantly, not super difficult. The coordinates of this cache page will take you to a small park at the end of the Washington Street Bridge also commonly known as the Old 202 Bridge.
Park at the "parking coordinates" and then walk an extremely short walk to the posted coordinates to start this field puzzle!
The final cache location is at N40 53.ABC W074 24.DEF
Use the information plaques at the posted coordinates to solve for the missing numbers to the final coordinates. The final cache is a bison tube with a micro log book in it. Good luck and have fun!
A - How many information plaques are there in total? Multiply this number by 2 for "A".
B - "Exclusive use of concrete would not become common until the 19_0's." The missing number is "B".
C - The Washington Street Bridge is how long? Remember the last digit of this number as it serves for "C".
D - "The reservoir can be drained from the bottom by two __ inch pipes set in concrete at the base of the dam." Take this number and divide it by eight. The quotient you are left with serves as "D".
E - In 1988 repairs were made on the _ northern spans. This number is "E".
F - The upper dam was constructed between 190_ -- 1904. You now have "F".
Congratulations to RoxburyDevil on getting the first to find!
