A sheet metal bivouac just below the top of Grimming.
The bivouac is equipped with a solar panel. The door can be closed with a latch.
The mobile signal is 10 m from the bivouac.
The sign in the bivouac reads: If our bivouac helped you as an emergency shelter, it was worth building and maintaining it. Leave him alone, hoping to find him. Take your waste with you, leave the emergency bivouac in a dreamy atmosphere and hang the sleeping bag on a pole that is for that purpose. We wish you good luck! Sincerely, climbers, Stainach Mountain Service Department.

Probably at any time...
Still up on Grimming :-).
