Sourdough Island on Salmon Lake Heliport serves Seeley Lake, US.
Sourdough Island on Salmon Lake Heliport (US-11757), also known by its former identifier MT56, was officially closed due to FAA deletion on January 15, 2009. The site was originally created in 2008 as "Sourdough Island On Salmon Lake Heliport".
Historically, locals referred to it as a heliport because emergency helicopters from Missoula would land there for snowmobiling accidents. The heliport was situated near Seeley Lake, Montana, with coordinates around 47.1046° N, -113.411° W.
Currently, the site is marked as closed, and the original MT56 identifier is now associated with "Flying Dog Airpark, Billings MT". While the heliport itself is closed, a 2013 aerial view of the nearby original Seeley Lake USFS Airfield (which was replaced between 1960-1965) still depicted a helipad on its southeast end.
