"Sir George Simpson in his narrative of his journey across the mountains in 1841 makes mention of a party of emigrants who came from the west that same year by way of Kootenay River and one of the passes through the mountains, under the guidance of an Indian named Bras Croche. The party probably travelled by White Man Pass. In 1845 the Reverend Father J.P. De Smet ascended the Columbia River and crossed the main range by a pass that seems almost certain to have been White Man Pass. In his book "Oregon Missions and Travels over the Rocky Mountains in 1845-6" he describes the erection of a cross at a point at which he traversed the watershed; he refers to it as the "Cross of Peace." The branch of the Cross River flowing southward from the summit of the pass to the Kootenay River is, acording to Dr. G.M. Dawson, called by the Stoney Indians Tsha-kooap-te-ha-wap-ta, in allusion to the circumstance related by them that some early traveller set up a cross in the pass not far from the summit, probably De Smet...."

The Indian name for the pass. The first white man to use it was James Sinclair who led a party of emigrants throught it in 1841 on their way to Oregon. He was followed in 1845 by Father DeSmet, who set up a wooden cross at the summit.
