Broad River Cryptography #4: Transposition Cipher Mystery Cache

This cache has been archived.

profzoom: This puzzle series was an absolute blast to put together, and congratulations to the brave few who went through the effort to solve them! The original goal was to have 15 caches forming geoart in the shape of the Greek letter/mathematical constant pi (π), but I never did get around to finishing those last two puzzles.

Due to the low find count and difficulty of keeping all 13 caches maintained, I've decided to archive the series.

Geocache Description:


The purposes of this geoart series are twofold: to bring cachers to the watershed of the North Fork of the Broad River in Stephens and Franklin Counties and to serve as an introduction to the fascinating field of cryptography.


Consider the following message:

GEOCACHIN
GISAREALW
ORLDTREAS
UREHUNTHA
PPENINGRI
GHTNOWALL
AROUNDYOU

Now we can encrypt this message by reading vertically along each column, i.e.,:

GGOUP GAEIR RPHRO SLEET OCADH NNUAR TUION CERNN WDHAE TGAYI LAHRL ONWSA ILU

This is an example of a transposition cipher. There are many variations to this cipher. For example, we certainly could have arranged the message in something other than a 7x9 rectangle. We could also have shuffled the order of the columns, or read the letters off in some completely different way, like spiraling around the grid. We just need to shift the positions of the letters using some regular system.


To find this geocache, decrypt the message below using a transposition cipher.
