The second day weclimbed the steep east bank of the canyon, here 1,000 feet deep (fig. 2),crossed Cold Creek and Ash Creek Canyon below timberline, and reached 12 NORTir AMERICAN FAlXA. Brewer Creek Canyon in tlie upper part of tlie wliite-bark pines. Find-ing; absolutely no grass or other feed for the animals liere, we crossedthe canyon lower down (a little below the forks) and continued onover rough lava ridges in the ui)per edge of the foiost until dark,when we camped on Inconstance Creek (hg. 3). The third day we pushed. Fici. 3.—Shasta from Incoustiiiice Creek, near tiiiilicrliiu^ on uortli side. on around the north end of the mountain, keeping a little below thegreat glaciers, and in the main near timberliue. We climbed over anund^er of lava ridges, availed ourselves of a natural passageway(ISTorth Gate) at the upper end of a pair of coTisi)icuous lava buttes,traversed a curious pumice plain covered with timberliue nuits ofprostrate white-bark pines (fig. 22), crossed the fearful canyons of Whit-ney and Bolam creeks, and finally reached Shastina, Mhere, after a verysevere day, we camped on some small streams of snow water on thenorth side (fig. 4). The fourth morning we clind)ed the rough slide rockof Sliastina to an altitude onO,()00 ivv\^ in order to get around a highimpassable lava ridge, and then, after encircling a great amphitlieaterof rough slide rock, descended by some iminense masses of perpetualsnow to the white-bark ])ines, i
