Randonnée au départ du hameau de Juta vers le lac du Chaukhi, la randonnée classique de cette destination très touristique en été, puis au-dessus vers la combe ouest du Chaukhi sous les murailles de conglomérat des sommets éponymes et sur les glaciers en fin de vie du coin. Aux processions de touristes à pieds ou sur des chevaux succède dès le lac passé une montagne caucasienne sauvage, avec une ambiance qui devient plus haute montagne. On progresse sur fond de Kazbek sur d’anciennes moraines au-dessus de bourrelets rocheux caractéristiques de glaciers rocheux jusqu’à atteindre les restes de glaciers en fin de vie (demi-tour à 3400 m), où bédières et moulins découpent ou trouent la glace vive souvent recouverte d’éboulis. Les blocs de conglomérats vert, jaune, bleu et rouge charriés par ces glaciers interrogent sur la géologie de ces aiguilles à l’allure dolomitique, conglomérats d’origine sédimentaire ou magmatique ?
