Incorrect!
Or at the very least, very misleading - this is not Roaring Springs; it is the Pumphouse Ranger Station. Roaring Springs is another 1+ km up the North Kaibab Trail. Perhaps this is the "residence" near Roaring Springs, but it is not the Roaring Springs stop. Now, having said this, the Roaring Springs stop is a short branch off of the North Kaibab Trail, so maybe you want to fill up here anyway.
