Weeping Wall, Natural waterfall in Glacier National Park, Montana
Weeping Wall is a 100-meter-wide rock face in Glacier National Park where water seeps continuously through the stone at multiple points. The flowing water creates small streams down the slope and supports a lush, damp zone along the roadside.
The rock face became visible in the 1930s when road workers blasted through the mountain during construction of Going-to-the-Sun Road. They uncovered underground water sources that have been flowing continuously since that time.
The formation serves as an educational site where visitors learn about the geological processes and water systems within Glacier National Park's ecosystem.
Water flow is strongest during spring and early summer months when snowmelt feeds the mountain aquifer. The best views of the wall are from the roadside pull-off, where you can safely observe the water without leaving your vehicle.
During peak water flow periods, the spray reaches across the road and can soak vehicles passing the rock face. This unexpected soaking surprises many drivers unfamiliar with the feature.
