岳

岳 = 丘 + 山 : Yu the Great (yu) buried his wife's parents and paternal uncles (岳) in the elevator's bathroom (e4). For each of them he set up a small mound (丘), and his wife's parents got the highest peak of the mountain ridge (岳). It was very hard for him to pile up the mounds because he used a fork (山) to do so.

丘 = 丿 + 丨 + 工 : In front of the outhouse (ou1), the Queen of Hearts (qi) set up a mound (丘) for her relatives. She also put a gate in front of it where the two pillars are a steel beam (工) and a dinosaur bone (丨) respectively, and the horizontal beam is a banana (丿).

山 = 丨 + 凵 : Mnemonic symbol: 山 looks like the tip of a fork. Sherlock Holmes (sh) is climbing a mountain (山) in front of the anthill (an1). He uses a dinosaur bone (〡) as walking stick, and to have better grip he attached a fork (山) to its tip. Unfortunately he accidentally sticks the fork into a receptacle (凵) on the ground of the mountain and gets shocked.
