According to TetonHikingTrails.com, "the lake was named for a Shoshone Indian named Jenny who assisted with camp logistics during the Hayden Geological Survey of 1872. Nearby Leigh Lake is named for her husband, Richard "Beaver Dick" Leigh, an itinerant trapper and early tour guide who helped guide the Hayden Expedition through the area. In 1876 Jenny and their six children died of smallpox."

Parking for this hike is plentiful, including space for RV's or trailers. Water and restrooms are also available seasonally. Though the loop can be completed in either direction, consider hiking the loop counter-clockwise for the best views of the mountains.
