We did a touristy thing and visited Historic Crystal Cave | First Show Cave in Pennsylvania (crystalcavepa.com). The history page is intersting. The cave was discovered in 1871 and some of the rock formations are a half-million years old (Crystal Cave (Pennsylvania) – Wikipedia.)
I’d love to visit and explore a cave like this!
A wonderful cave Sherry and thanks for the link of the homepage.
Have a nice evening and lots of greets, Rudi
Your welcome Rudi. Thanks.
I vaguely remember visiting Mammoth Cave in Kentucky as a child. Today? I’m not sure I’d do that again, so I’m glad you provided these neat photos, and the memory.
One little boy was upset and in tears at being underground.
