The mythical high point in the Catskill Mountains. Thus named when that area was a vacation spot, mostly for Jews, and the training ground for many later day Vaudeville comedians. e.g., Bert Lahr Oz's Lion, Georgie Jessel, etc., and because of it's similar sound to Pike's Peak
"They were staying at that hotel near Kike's peak." "Ven you hear da goyem say Kike's Peak, dats usually a racial slur."
