The first carvings were discovered in autumn 1972 in the area of Jiepmaluokta (a Northern Sami name meaning "bay of seals"), about 4 kilometres from the town centre of Alta. During the 1970s, many more carvings were discovered all around Alta, with a noticeably higher density around Jiepmaluokta (of around 5000 known carvings in the area, more than 3000 are located there). A system of wooden gangways totaling about 3 kilometres was constructed in the Jiepmaluokta area during the second half of the 1980s, and Alta's museum was moved from its previous location in the town centre to the site of the rock carvings in 1991. Although several other sites around Alta are known and new carvings are constantly discovered, only the Hjemmeluft locality is part of the official tour of the museum.
Most rocks around Alta are overgrown with a thick growth of moss and lichen; once carvings have been discovered, these plants are carefully removed and the rock is cleaned to expose the full extent of the carvings. The carvings are then documented using different techniques, most often the combination of quartz powder painted into the carvings which are then photographed and digitally treated.
