Hello, my name is Oier Gorosabel Larrañaga, from Basque Country, and I use this account to feed Wikimedia Commons with my photographs.
Much of them are relatives to speleology, as I participate in ADES Espeleologia Elkartea, an speleological group from Gernika-Lumo. In fact, I manage ADES’ account too (username: AdesSpeleo), which we use to upload collective works of the group.
NOTE: In august 2021, I have fixed some attribution mistakes between these two accounts: when I started to participate in Wikipedia, I uploaded some images in my name, that should be attribued collectively to ADES. I hope to have done it in the right way.
