OnThisDay in 1935, Penelope Powell and Graham Balcombe did the first-ever cave dive. They did it here in Somerset in Wookey Hole Caves.

More on Penelope in Unsung Women in Somerset (Junior Edition), coming in autumn.

After lots of effort, I got #CaveDive certified! #NAUI #NAUITEC

I’m really excited about it. I learned so much!
