This 2-stage multicache is a challenge. It's Difficulty rating of 3.5 reflects the challenge of computing the final stage grids from a virtual and then finding a nano container in the park. The terrain rating of 3 reflects the distance of the hike (3-miles plus round trip), rough terrain approaching the CZ (rocky terrain, and stream fording (springtime)) along with the abundance of thorns, PI and crawling critters. Take plenty of water and recommend bug spray unless there is snow on the ground. The trails are only open during daylight hours, DO NOT go after this cache in the dark.
Stage 1 is a virtual stage. At the posted coordinates you will find a brown trail post. On that trail post are four small, square stickers. The second sticker down is white with a five-digit number (brown in color). You will need this number to calculate the coordinates for the final stage (stage 2).
Stage 2 is a virtual located at N38 5A.BCD W094 5E.FGH.
A = third number minus fourth
B = fifth number
C = fourth number
D = fifth number plus first number
E = fourth minus first number
F = third number minus fourth number plus first number
G = third number
H = A
