The upper section of the Theodul Glacier consists of a flat plateau at around 3,800 metres, named Breithorn Plateau. The plateau lies between the Breithorn, the Gobba di Rollin and the Klein Matterhorn. The Breithorn Pass (3,814 m) separates the Breithorn from the Gobba di Rollin (). A 3,795 m high saddle lies between the Gobba di Rollin and the Klein Matterhorn. Between the Klein Matterhorn and the Breithorn is a distinct glacier, named Klein Matterhorn Gletscher, which joins the Lower Theodul Glacier at about 3,000 metres. The Breithorn Plateau area can be easily accessed by several cable cars connecting Zermatt to the Klein Matterhorn.
