Set for the 2018 Winter Geolympix FTFrenzy, with permission from and help by the National Trust. This puzzle-style Letterbox/Hybrid cache isn't hidden at the given co-ords, although it is within two miles or 3.2Km of it.
The Puzzle: Fill the grid below (it may help to print it off as large as you can fit on a Landscape A4 page) to get the letters identified by arrows, convert A-to-Z to numbers in the time-honoured way (A=1, B=2.. J=0.. Z=6) and head to:
N51 4a.bcd
W000 3e.fgh
Where:
a=C+R+V
b=T+(E-N-W)
c=F
d=((I-B)xK)/(D+G)
e=(J+Y)-(L+S)
f=(H+O)-(U+Z)
g=Mx(Q-P)
h=A+X
...where you'll find your prize. It's close to a less-than-obvious path so please DO NOT bushwhack your way to the location - There is better access to this spot if you look for it.
Note the values for J and L in this cache/s final co-ords to help you find FTFrenzy cache 10 for a Bird You Must Not Miss! - Please DO NOT remove the stamp or ink pad. Neither is a swap - They make this cache a LetterBox/Hybrid. Thank you!
