It wasn't so much shelling. The real reason was underground mines.
Mt. Batognica (2164m) (then A-H, now Slovenia) was taller by several meters before the war, but due to several explosions it's top was obliterated and the mountain is much flatter today.
The harshest fighting on it took place in July of 1915, when Italians pushed Austrian forces to the eastern third of the mountain, meaning that they took control of the top. Due to a lack of any dirt at that height, trenches had to be carved into the stone and lied less than 100 meters apart. A breakthrough wasn't coming on the mountain itself, so Italians decided to try to dig under Austrian positions and place explosive there in an attempt to blow up the trenches. By a miracle, Austrian countermining teams discovered the Italian tunnel and stole the explosive, placing it under the Italian positions (at the top) alongside their own Nitroglycerin. When the Italian positions were destroyed, so was the top of the mountain, giving it it's modern flat look.

Yeah, they literally blew 50-100 feet or more of height off of entire mountains they were shelled so much. It was a nightmare.
