Pitchpole is formed from "pitch" (from Old English *pic*, meaning a sticky substance) and "pole" (from Old English *pal*, meaning a long, slender piece of wood). The word refers to a long pole used in the sport of pole vaulting, where the pole is often coated with pitch for better grip.
Think of a 'sticky substance' ('pitch') used on a 'long piece of wood' ('pole') to help in vaulting over heights.
