Hanging Lake was formed by a geological fault which caused the lake bed to drop away from the valley floor above. Over the years, water flowing over Bridal Veil Falls has deposited dissolved carbonates to build up the fragile lake edge. Because of its uniqueness, the area was designated a National Natural Landmark by the Secretary of the Interior in 2011.
Over the years the popularity of the area has increased leading to vegetation, trail damage and overcrowding. A management plan was put in place in 2018 to protect this natural wonder into the future. A percentage of the fees collected for reservations will be reinvested into the long-term stewardship and sustainability of Hanging Lake. The implementation of the permit system, environmental education and interpretation program will help visitors play an active role in protecting the ecological health of Hanging Lake, improve the visitor experience and support the local tourism economy.
