The King Leopold Ranges are a range of hills in the western Kimberley region of Western Australia. Crossed by the Gibb River Road about 134 kilometres (83 mi) east of Derby, part of the ranges are covered by the 3,921 square kilometres (1,514 sq mi) King Leopold Ranges Conservation National Park, managed by the Department of Environment and Conservation. The ranges separate the main Kimberley plateau from the southern Fitzroy plains and consist of quartz sandstone intruded by dolerite.
The ranges are shaped like a crescent with a length of 567 kilometres (352 mi) running from the northern end of the Durack Range in the East to east of Secure Bay in the West Kimberley. The range is estimated to cover a total area of 30,794 square kilometres (11,890 sq mi).[1]
The ranges, which have an average height 600 metres (1,969 ft), were named by Alexander Forrest in 1879 after King Leopold II of Belgium. The highest point of the range is found at Mount Wells which is 983 metres (3,225 ft) above mean sea level.[2] The next two highest peaks are Mount Ord at 936 metres (3,071 ft) and Mount Broome at 927 metres (3,041 ft).
Nearby features include Mount Hart, Bell Gorge, Silent Grove and Lennard Gorge as well as the Napier Range and Queen Victoria's Head granite outcrop. Fitzroy Bluff is formed where the Fitzroy River carves through the range. Camping is permitted at Mount Hart, Bell Creek or at Silent Grove.
The traditional owners of the area are the Ngarinjin and Bunaba peoples.[3]
The ranges are a distinct physiographic section of the larger Kimberly Block province, which in turn is part of the larger West Australian Shield division.
The King Leopold Range is made up of many smaller ranges including; Lady Forrest Range, Isdell Range, Narrie Range, Sir John Range, Precipice Range and Durack Range.
