The park is physically split into a northern and a southern half by a corridor containing the Hamersley & Robe River railway and the Marandoo iron ore mine .

The Banyjima name for the Hamersley Range is Karijini ("Hilly Place" in English). Evidence of their early occupation dates back more than 20,000 years. During that period, Aboriginal land management practices, such as "fire-stick farming", resulted in a diversity of vegetation types and stages of succession that helped determine the nature of the plants and animals found in the park today. A party led by explorer F.T. Gregory explored the area in  1861. He named the Hamersley Range, on which the park is centred, after his friend Edward Hamersley. Climate. The park is located in the Pilbara region, and is mostly tropical semi-arid climate. In summer, thunderstorms and cyclones are common, bringing 250–350 mm of rain annually.
