In 1862 Payer had started exploratory tours of the Tyrolean Alps and the High Tauern range in his free time. After 1864 he explored the Adamello-Presanella Group and the Ortler Alps, making more than 60 first ascents. In 1864 he was, with his guide Giovanni Caturani, the first to climb Adamello and missed making the first ascent of the Presanella by just three weeks. All his explorations in the Ortler massif were guided by :de:Johann Pinggera from Sulden. Together, often accompanied by a porter, they ascended almost all significant unclimbed summits, including the Hoher Angelus, Vertainspitze, Palon de la Mare, Monte Zebru, and Monte Cevedale. Their new approach to the Ortler became the normal route of ascent ever since. His tours resulted in creating a detailed topographical map at a scale 1:56,000. Due to his achievements, Payer was transferred to the Austrian Military Geographic Institute. When in 1875, the first Alpine club hut above 3000 m was built on the normal route to the Ortler, it was named :de:Payerhütte in his honor.
Polar expedition
In 1868 he was invited by the German geographer August Petermann to participate in the 2ndGerman North Polar Expedition as a topographer. Travelling to the coast of East Greenland on the Germania under Captain Carl Koldewey in 1869-1870, they reached as far north as Shannon Island. In 1871 he participated in the preliminary Austro-Hungarian expedition to Novaya Zemlya, with Karl Weyprecht. From 1872-1874 Payer led the Austro-Hungarian North Pole Expedition with Karl Weyprecht, who was Commander at sea, while Payer was Commander at shore. During this voyage he made the discovery of Franz Joseph Land, however upon his return to Vienna many critics voiced doubts about its existence and about the experiences of other participants in the expedition. Payer could have proven his statements using testimonies, diaries and sketches, however his efforts were thwarted, including his promotion to Captain. In 1874 he resigned from the army because of political maneuvers against him and his brother officers' doubts about his discovery and his sledge journeys. He was awarded 44 Austro-Hungarian gulden on 1 October 1874 for the discovery of Franz Joseph Land. He was also awarded the 1975 Royal Geographical Societys Patron's Gold Medal. However, on 24 October 1876 he was elevated to the Austrian nobility which entitled him and his descendants to the style of Ritter von in the case of male and von in the case of female offspring.
Later life
In 1877 Ritter von Payer married the ex-wife of a banker from Frankfurt am Main. They later had two children, Jules and Alice. From 1877-1879 he studied painting at the Städelsches Institut in Frankfurt / Main. From 1880-1882 he continued his study of art at the Akademie der bildenden Künste in München. From 1884-1890 he worked as a painter in Paris. In 1890 he divorced his wife, returned to Vienna and founded a painting school for ladies. In 1895 he planned a trip for painting to Kejser Franz Joseph Fjord in northeastern. In 1912 he planned an expedition in a submarine to the North Pole. He died in Veldes, in historic Upper Carniola, today part of Slovenia, in 1915.
Named after Julius von Payer
Besides the Payerhütte mentioned above and several streets in Vienna, the main island of Franz Josef Land, the Payer Mountains in Antarctica and Payer Land in eastern Greenland have been named after Julius von Payer. The southern satellite camp for the PolAres MARS2013 analog mission by the OeWF, approximately 80 km south of the base camp near Erfoud, Morocco, was named Station Payer during February 2013, after the main base camp had been called Camp Weyprecht during the landing ceremony in the morning of February 11, 2013.
