Is Carnegie going to be affect by the closing of National parks?

Park remains open some trail closures due to some off trail riders. But like above this park is state owned not federal

No! Carnegie SVRA is a State Park, not federally controlled National Park. Carnegie is open 365 days a year, unless there is major flooding or fires. Trails are subject to closure if more than 1/3 inch of rain falls within the last 12 hours or if off trail riding has occured. Valley floor and tracks are always open.
