On October 19, 1826, while travelling south between Upper and Lower Arrow Lakes, Simpson passed "...The Arrow Rock, so named on account of a round hole in the face full of Arrows, said to have been fired at it by the Indians when practicing the Bow and Arrow before a war excursion." (Journal of Emilius Simpson; HBC Archives' accession B223/a/3 1826 Folio 39D-41) Source: included with note
In the days before Columbus was born, the 'Indians' of the west and east Kootenay were at continual strife. It was customary for the west Kootenay Indians to winter along the southern Columbia and to ascend the stream every summer, to the lakes where hunting was good. As the tribes in the Slocan were always on the alert for war, they had their scouts out on the Arrow Lakes to note when their enemies came up the river. One summer the scouts returned from the () Lakes with news that a particularly large force of warriors were going up the river. So the Slocan tribes prepared for war and crossed the mountains in force to Nakusp. On embarking from their canoes at Nakusp (the bay behind the long point) they noticed signs of a great storm having passed. On proceeding up the lake for some distance they came upon the force of the enemy. But alas ! There were none to resist them, for the great storm had apparently come suddenly upon them and there was nothing left but a heaving mass of canoe wreckage and dead bodies. The Slocan Indians took this as a great favour from the great 'Manatoo', and in token of respect they fired all their arrows at the high rock off which they lay, and wrote inscriptions on the face of the rock. Because of the vast wealth of arrow heads that fell to the bottom of the lake that day, the Indians named it Arrow Lake. (Relayed by Richard Blyth, as told to him by Chief Louis Joseph, Burton.)
