Remember when it was all just maps & compass, no satellites to show the way and grid references were how we communicated locations.
So here is a little challenge to revive your map reading skills.
All the grid references are found on map "Explorer 284 Grimsby, Cleethorpes & Immingham". So spread the map out and get hunting.
(I've given the references in 10 digit format for those of you who want to use a magnifying glass! With a bit of thought this puzzle can be done without spending a penny)
A:TA 16362 09002 contour height
B: TA 16231 16114 the Number of large tanks in rectangle
C: TA 18897 01352 the spot height
D: Height difference in metres between TA 10515 08992 & TA 18890 04287
E: TA 31500 01620 the number of ways
F: TA 13045 16845 how many sides?
G: TA 30090 08923 the first red digit
Now substitute your answers into the following
N 53º A.BC W 0º D.EFG
