According to NPR, the ibex has taken to the dam because it's covered in salt, which is a mineral the animals crave. They're able to balance on four legs while moving vertically up the steep wall, taking the time to lick the stone, too.
Look how chill they are. “Yeah dude, just here for the salt. This spot's got the best salt.”
The alpine ibex is our bro of the week.
