OverviewJupiter Mountain is at Needle Creek's head, 0.6 miles south of Windom Peak and fifteen miles south-southeast of Silverton. It is the 92nd highest peak in Colorado.
Jupiter is the first prominent peak one sees while hiking up the Needle Creek Trail into Chicago Basin in the Weminuche Wilderness, Colorado's largest. From the summit, there are great views of the Chicago Basin fourteeners Mount Eolus, North Eolus, Sunlight Peak & Windom Peak, Jagged Mountain and The Rio Grande Pyramid. The Southwest Slopes Route is Jupiter's standard and easiest route and the only route that should be climbed during snow free periods.
Getting ThereJupiter Mountain's Page describes the involved approach. The best place to camp if attempting Jupiter Mountain and the Chicago Basin Fourteeners in the same trip, but different days is near the upper Twin Lakes and Columbine Pass intersection at 11,200'.
