Three Fingered Jack in the background.

Jack Lake is a small lake that sits at the trailhead for the Canyon Creek Meadows trail which leads to the base of Three Fingered Jack. Jack Lake is in the Jefferson Wilderness near Santiam Pass and is about a 30 minute drive from Sisters, Oregon. The lake is at the end of a long and bumpy dirt road that does not require 4×4 but would be helpful. The lake is at an elevation of 5150ft.

Three Fingered Jack lies in Linn and Jefferson counties. It has a volume of 2.4 cubic miles (10 km3) and a summit elevation of 7,844 feet (2,391 m), with a proximal topographic relief of 1,300 feet (400 m) and a draping relief of 4,600 feet (1,400 m). Its jagged edifice rises between Mount Jefferson and the Three Sisters volcanic complex. Three Fingered Jack lies within the Mount Jefferson Wilderness and is not accessible by paved road, but can be approached by the Pacific Crest Trail. Located about 20 miles (32 km) northwest of the city of Sisters, it acts as a prominent landmark in the area.
