There should be loads more to come...
Constant drought conditions is why all the Roman archaeology in Australia is so visible. I didn't even know grass was green until I lived in Europe.
Hopefully you dig up some of those dry and dusty Welsh sites and find the Sutton Hoo ver.2?
Dry and dusty are adjectives not normally paired with Wales... ;D
FWIW, In 2012 I attended a job interview with an Arab from one of the region's oil companies. This took place on the 36th floor of Centre Point in London and, as I entered the meeting room, he was staring out of the window at the torrential rain falling outside. Bizarrely, a couple of weeks previously Thames Water had declared a state of drought due to low winter rainfall.
So, in the time-honoured English tradition of starting all conversations by remarking on the weather, I opened the interview with "You appreciate that we are in the middle of a drought?"
He offered me the job.
;D
Given the number of droughts we've had since the advent of aerial photography and satellite photography I'm surprised there is much left to discover :)
