An Old School Multi Multi-Cache

This is an old school multi. A simple one step – get the info – work the info - and find the final.

I had noticed a dearth of easy multi’s and puzzles in the area, and thought I needed to do something about it. While a group of my friends where climbing to the wreck of the Stinson Plane nearby I thought I would use my time productively!

Go to the icon to find the information nearby that can answer these questions. You are looking for a plaque and the surrounding area.

Here are the questions:

What is the Magic Reducing number of all the numbers on the plaque = A

(The magic reducing number is achieved by adding all the numbers together to one total, then adding all the numbers in the answer to one number until you reach a one digit answer)

The total number of lines of writing and/or numbers in the plaque = B

The number of letters in the 4th word on the last line of the plaque = C

The number of words on the entire plaque divided by two = D

If the line of numbers on the plaque were a Math’s Exam question,

what would the answer be ? (Remove the negative sign in the result) = E

The number of letters in the 5th word on the plaque plus one = FG

The 66^th letter, the 79^th and the 63^rd letter spell H
