The maps below were given to Paul C whilst he was in Oman. They were the usual maps that every man and his dog used and give a general idea (!) of where the major features were situated.
I imagine that were you to be on foot and expected the next wadi to be 500m distant you might well be disappointed and need “to go a little further”.
I am grateful to Paul for digitising these maps and making them available.
They can be manipulated to increase the contrast or to sharpen up the resolution if desired
