Iona anchors this Lyman County landscape, situated where the high plains begin to break into the drainage systems of Waterhole Cr and Nicholas Cr. The settlement is defined by local heritage sites including Saint Columba Catholic Cem and the Iona Cem, both located near the intersection of 266th St and the highway. The surrounding terrain transitions from the level expanse of Gozzard Flat in the north to the more complex relief of the Iona Hills and Twilight Butte in the south.
