1954 Map of Deer Island

Evidence of local development and community life is found in the scattered rural landmarks, including the County Fairgrounds and schoolhouses like Cloverdale Sch. The landscape rises sharply from the river flats toward Maple Hill and Green Mountain, where the Old Pacific Highway winds through the hills. River navigation is facilitated by several range markers, such as the Columbia City Range, which guided vessels through the Martin Island Channel during the mid-century era.
