Another name clue?

[Geoff Bannister]

No: HPFGUIDX 100762

Last week, I was on holiday in North Yorkshire. This is a geological 
area renowned for its limestone which creates a huge number of caves 
and potholes.

So what?  Well, I was staying in Ingleton and, while studying the 
large scale OS map of the area, my eye lighted casually on an area 
about three miles from where I was staying and,to my great surprise, 
I found myself looking at "Boggarts Roaring Holes", a series of pot 
holes at approximate Grid Reference SD 727728.

The thought crossed my mind that JKR collects name sources from a 
wide range of sources. If there something here that we should know?
