Clubs de montagne, marques outdoor et sites de tourisme peuvent utiliser cette page d'erreur de montagne. Un poteau en bois balisé de rouge et blanc porte des flèches vers le refuge, le belvédère et le départ, tandis que la planchette de la page 404 pend à un seul clou et qu'une aiguille de boussole tourne sans trouver le nord.
Le fond trace des courbes de niveau avec des dégradés répétés, sans aucune image. Au survol, chaque flèche vacille, et en mouvement réduit la planchette reste immobile. Change le vert forêt et relie le bouton à ta page d'accueil.
