SuburbMount ColahTypeCreekDetailsApple Tree Creek rises at Mt Colah and drains into Apple Tree Bay in Cowan Creek. The creek was probably named because it ran into Apple Tree Bay. Apple Tree Bay was named by Surveyor Larmer in 1832, his map showed an apple tree on the bay's northern entrance. Larmer tended to use prominent trees as points of reference.
