During his 1892 visit to the Rockies, Arthur Coleman left his packhorses and "tramped" up the Chaba River in search of the elusive Mount Brown and Mount Hooker. Following the third night out the party climbed made an unsuccessful attempt to climb the mountain that they named Fortress Mountain. The following day they reached a high point to the west of Fortress Mountain and saw a, "white pyramid beyond the glacier to the south." On August 23rd they set out for the Pyramid Mountain (now known as Mount Clemenceau). They encountered difficulties with crevasses, weather and visibility, turning back after reaching 9900 feet. The following day they retraced their steps and reached the summit of Misty Mountain (now known as Brouillard Mountain). They then determined that the mountain they had been referring to as Pyramid Mountain did not join the mountain that they were on. "Its top was probably two thousand feet above us and thre or four miles away, and it seemed very isolated, so that we had to forego any attempt at climbing it, since our supplies were low... Thus far this splendid peak has never been approached by a white man except on our climb of Misty Mountain." [See Arthur Coleman biography]
