There is a legend about Lake Finsberg. In the older days. The legend says, at the time when there was much reindeer on the north of Hardangervidda, then there was an extensive hunting of reindeer at the lake. In the middle of the south shore is a level and low spit of land that draws together the lake to a narrow sound. It is said that it was here in the sound that the hunting was carried out. Animals on move on the north side were driven in to the water, stabbed and beaten to death while they were swimming and then dragged ashore on the spit of land and slaughtered. Sumtangen is the name of the place. The hunters used long rows of cairn sandwooden sticks with ropes between says one of the legend variants.The rows stretched several kilometers out in the terrain in the form of a funnel that was wide farthest out, but got narrow towards the sound. When the animals entered the funnel they were lead straight into the water. In it were stretched outlines that prevented the animals from swimming to the sides. At the spit of land on the southside [of the sound] the hunter slay ready in boats waiting.
