It is an example of a geographical feature known as a tripoint. A monument of stones was erected on the site in 1897 by the governments of Norway and Russia (which was administering Finland at the time). The Swedish could not agree on a boundary commission with the Norwegians and did not contribute their stone until 1901. This is Sweden's most northerly point and it is the westernmost point of the Finnish mainland (the most westerly point of Finland is on the island Märket). The current tripoint monument was built in 1926 and is a beige, conical frustum made of concrete, located about {{convert|10|m}} out in Lake Goldajärvi (also known as Lake Koltajauri). It is located at {{convert|489|m}} above sea level. The size is about {{convert|14|m2}} with diameter of about {{convert|4|m}}. As an artificial island, it is sometimes mentioned as the world's smallest island divided by a border.{{Citation needed|date=June 2011}} This is a matter of definition. For example, in Haparanda/Tornio there are poles in water marking the border. It may be reached by walking {{convert|11|km}} from Kilpisjärvi in Finland along a hiking trail in the Malla Strict Nature Reserve. In summertime, it can be reached by boat from Kilpisjärvi plus a {{convert|3|km|adj=on}} walk.[1] Climate{{Weather box|location = Treriksröset |metric first = Yes |single line = Yes |Jan high C = -9 |Feb high C = -9 |Mar high C = -4 |Apr high C = -2 |May high C = 4 |Jun high C = 10 |Jul high C = 12 |Aug high C = 12 |Sep high C = 6 |Oct high C = -1 |Nov high C = -4 |Dec high C = -7 |year high C = 0.7 |Jan low C = -20 |Feb low C = -20 |Mar low C = -16 |Apr low C = -7 |May low C = -2 |Jun low C = 4 |Jul low C = 7 |Aug low C = 4 |Sep low C = 0 |Oct low C = -5 |Nov low C = -12 |Dec low C = -18 |year low C = -7.1 |source 1 = SMHI.se[2] |date=November 2012 }} See also{{Commons category|Tripoint Norway Sweden Finland}}
