The North Sister lies to our left and the Middle Sister is in the right background and the high peak this side of Middle Sister is half way up the slope.
The climb to the summit of this mountain can be made from any side but north, and from the top magnificent views are to be had in all directions. "Old crater-tops! Cloud bumped! Snow-white! Our mountains these--all day and night The show above the ridges. What? You've never climbed. You've missed a lot."
This view shows the crater lake near the top of the South Sister. It is approximately 1/4 mile in diameter. During the summer, in this lake and around its shores at 10,000 feet elevation, one may enjoy swimming, skiing and skating, but the swim will probably be rather short.
The South Sister is the youngest and the highest of the three Sisters and also the most symmetrical. In this picture Broken Top is to our extreme right.
Mount Jefferson is the second highest peak in Oregon. There is no uncertainty as to its christening. On March 30, 1806 Captain Clark of the Lewis and CLark expedition from the Columbia River saw the tip of a white pinnacle outlined against the horizon far to the south, and he named it Mount Jefferson in honor of the President who had sponsored the expedition.
The Cascade Forest furnishes pasture for thousands of sheep which are driven in from Eastern Oregon for the summer season. Sheep eat forage very closely and sportsmen claim that deer will not stay anywhere near ground grazed by sheep. However this is a moot question.
