There are usual requests that no outside firewood is aloud as to not introduce new bugs or fungus in the area. That being said, I just called Eastern Sierra visitors center and they said outside they know of no absolute restrictions so it should be fine. Please just burn all the wood you bring and leave non behind. Also make sure you visit the Glacier Lodge while ur up there, they got beers, BBQ and fresh caught fish dinners.
Thank you for the quick response! We will check out glacier lodge as well!
