Former ranger Joe Cosley was fond of naming the natural features around his territory. The ridge and lake that now carry the name Cosley were of course named eponomously, but misspelled on maps and in literature for decades as “Crossley” before finally being corrected to the present, accurate form in the late 1950s.
