嶝
dèng
path leading up a mountain
mountain (山) + ascend (登) = path leading up a mountain
登 means to ascend or climb, so together with the mountain radical, the character naturally describes the route by which one climbs upward. The path exists precisely because of the mountain and the act of ascending it.
