Ernest Maxwell, of the Izaak Walton League in Idyllwild, remembers that Butterfly Peak was named by USFS Ranger Jim Wellman in 1949. They were fighting a fire when there was a question as to what to call it since the bum wasn’t near any named spot. Just then some butterflies wafted by and both the fire and the burning peak received a name. This “unofficial” penciled-in use-name was then lifted and applied to the next Forest map. Again, without any official deliberation, this name was subsequently employed by the USGS in 1959.
