Panoramic views of Vadret Pers from Diavolezza circa 1895 and 2023. The old photo location could not be reached precisely because it is now occupied by a building. In 1895 there were hardly any medial moraines on Vadret Pers because most of of this part of the glacier was within the accumulation area. Isla Persa is only a tiny rock outcrop between Vadret Pers and Vadret da Morteratsch (Photo 1895: ETH-Bibliothek Zurich, Bildarchiv, photographer unknown, Ans_06493-1-3, PD; 2023: Alean).
