Jenny Lake Professional Review and Guide
"A beautiful, small lake in the shadow of the Tetons. Bring your camera and fishing gear. Be aware of winds and waves, sometimes strong and developing quickly. Prevailing southwest winds can funnel through Cascade Canyon. Attractions include rocky shoreline and bottom, bird watching, hiking, and fishing.
Most of the lakes in this area, including Jenny Lake, were created by the gouging and scouring of glaciers tens of thousands of years ago. The first part of this 5-mile clockwise paddle of Jenny Lake’s shoreline takes you along the base of the mountains to the mouth of Cascade Canyon, the best example of the glaciated valley found throughout this range. A mass of ice more than 1,000 feet thick once flowed down this canyon, eventually pushing its pile of debris across from where you are now paddling and coming to a rest just to the east, where it left the high rim of land that forms the east shore of the lake."
