As our brain is specialized in the recognition of patterns, and giving sense to things without sense is its specialty (which can also be quite annoying in everyday life), it is little wonder, that we see faces, figures and characters in nature. I even find a lot of boobs and other private parts, but that’s maybe just me :-).
So on my last three hikes I focused my eyes for the letters of the latin alphabet and further down you can see what I got. I can really recommend to have an eye for those imaginary phenomenons. Research your own alphabet. It’s fun!
