Hi,
not in any way part of this community, but I just stumbled on this thread whilst looking on Google maps with my Grandfather for the former hotel at Dale House, 140 Dale Road, Matlock that my Great Grandfather owned, after noticing "Youd's Level Entry/Exit" across the road from there.
I understand this post is in no way conducive to your aims, nor directly relevant to caving, but it seems that the man who discovered the level was actually my Great Grandfather, Stewart Edward Youds - either that or this is a huge coincidence 🤣. Really very interesting, and mildly thrilling, to see that my family name has had something of an impact on an historic location, and caused some manner of debate amongst you guys.
If anyone had any knowledge on how the level was discovered, it would be greatly appreciated if they could share it, if for nothing more than to satisfy my curiosity. Either way, happy to set the record straight on the spelling of his first name 🤣
Regardless, I wish you all the very best. Stay safe everyone.
