Stuorrahanoaivi, tunturi ja Struven ketjun mittauspiste Enontekiöllä Lapissa
Stuorrahanoaivi is a flat-topped hill in the Lapland wilderness of Enontekiö, Finland, rising to about 600 meters above sea level. On its summit stands a survey marker from 1852, a simple metal pole that is part of the Struve Geodetic Arc, a line of measurement points stretching across Europe and recognized as a UNESCO World Heritage Site.
The survey marker was established in 1852 as part of scientific efforts to measure the Earth's shape, with a symbol engraved in the rock marking the measurement location. The original point was lost in 1895, but a central peg was later placed, and the site remains a testament to 19th-century geodetic work in this remote region.
The site is extremely remote and requires wilderness hiking experience, with unmarked trails and challenging terrain that demands trekking skills and good navigation abilities. Small huts are available nearby for overnight stays, and visitors should carry supplies for multiple days and prepare for changeable weather conditions.
Old remains of a triangulation tower and a stone cairn nearby suggest that earlier surveyors used these features as landmarks during their 19th-century work. These stone witnesses form a fascinating ensemble of tools from the history of scientific cartography.
