There is a three-sided hut built around the pipe outlet, with a light. Over the course of a winter, a lot of ice builds up from steaming and breathing and sloshing. The build up is in the form of fragile crystals on the ceiling and thick layers on the floor.
There are two pipe outlets, and once your jug is in place, you press and hold the button until it's full.
This is the button you push to make the water come out. Don't try it without gloves. I once lost a quarter-sized chunk of leather off a mitten when I tried to let go.
Incidentally, I lost the feeling in several of my fingers while taking the pictures for this post.
Ain't Alaska neat!
