This cache takes you to some historical markers set up on a pathway around the former St. Paul campus of a major company in Minnesota. You will gather numerical data from six markers, and use that info to determine the final location.
Stage 1: Although the middle letter in this company's name stands for "Mining", very little actual mining was done by the company. According to this sign, what year did the company do some low-grade corundum mining in Crystal Bay? A=Four-digit year divided by 2 (Use written data from sign, not year shown in photo)
Stage 2: Working at this company was often a family tradition. What was Otto Meissner's street address on Greenbrier? B=Three-digit address.
Stage 3: Helen Milbauer (in the Raw Materials area) celebrated her anniverary of employment in May. How many years for this anniversary? C=Two-digit number.
Stage 4: Brig. Gen Carl R. Gray, Jr. found that Scotch Cellulose Tape was invaluable to the war effort in 1943. How many inches long was each roll of the tape requested? D = Four-digit length divided by 4. (Hint- it was 3/4 inch wide, had a 3 in core, and came in a tin box)
Stage 5: February 8, 1951, an explosion rocked Building 12. How many TOTAL people were killed in the explosion? E= Two-digit fatalities.
Stage 6: The flagpole at the corner of Bush and Mendota was a prominent feature on the corporate campus. How tall in feet was it? F= Two-digit height.
Now that you have determined those six numbers, calculate these two three-digit numbers:
MMM = A minus (Twice C) minus F minus 2
mmm = (The average of B and D) plus E
The cache is located at N 44 57.MMM W 93 03.mmm
Good Luck!
