I did call Monday is the last day they are open.
Where does it say it’s closed on Labor Day? Everything I read says it’s open through Labor Day.
Their website says they close on labor day weekend. I would assume they are open through that Monday, but you may want to call them. 435-491-0618 https://www.fs.usda.gov/recarea/ctnf/recarea/?recid=70736
