Flint Quarries in Yorkshire and Lincolnshire

Here's a list, no idea about the quality of the flint, but if anyone does find a decent one, let us know.

thanks all
I have phoned round a few of these and some say they can supply, but in tonne units !!!!
and to be honest i wouldnt know good quality from bad.
being a brand new knapper i only want half a doz nodules to get started!
any suggestions ? id be prepared to collect and pay for it of course.

Quality tends to be black with as few things in it as possible. The greyer the harder to knap.

I'd ask the quarry about the quality of their flint before going. Most quarries will let you grab a few nodules for a tenner.
