>>7130593that image intrigued me too. someone on reddit claims its of an Autro-Hungarian soldier and stated it's "on the slope of Gisnitz in 1916"
Did a quick google search and this pic comes up a few times with that reference. I only spent a few minutes on it but I found a girnitz river in Germany, couldn't find a Girnitz mountain. Did find this phrase though: Gisnitz aus der Vogeltesserstellung - translator says "gisnitz from the bird teaser"
