The high point on the east entrance road is at Sylvan Pass at 8,524 ft. The east entrance station is at 6,951 ft so it's a drop of 1,524 ft. Using the 5 miles mikim mentioned, that's 320 ft decent/mile or about a 6% average grade. I just used Google Street View to "drive" the east entrance road from Sylvan pass down to the east entrance station and see no grade warning signs. The only switchback is along the climb to Sylvan Pass from Yellowstone lake.
After the entrance station it's a long gradual descent for some 50 miles to Cody.
thank you that's what I'm looking for. I think I'd prefer to go up the grade as opposed to down since I have no exhaust break.
