Surmount is formed from "sur-" (meaning over or above) and "monter" (from Latin "montare", meaning to mount or climb). The word describes the act of climbing over or overcoming something.
Think of going 'over' ('sur-') something that you 'climb' ('monter') — that's why surmount means to overcome or rise above.
