I have been in the area for 3 months now so I decided to hide a cache. I decided to dedicate this cache to my job as an Air Force instructor. You must solve the puzzle below to find the actual cache location. I like math so decided to include it in this puzzle. You are looking for a decon container. Please remember to completely snap the lid on the container to ensure it is completely closed. I would recommend long pants.
N 30 2A.BCD W 89 0E.FGH
A = (1:4)+1
B = (32:3)+(42:7)
C = (1:17)-(2:11)
D = ((42:7)+(42:8))-1
E = (42:7)-1
F = (32:1)-3
G = (1:19)+1
H = (2:13)-2
