Recent history

In the 1850s, there were mines in the mountains. In 1890s and 1900s, an area of the mountain range had been reserved for forestry. Construction of the first "sealed road" over the mountain range began in 1960. It allowed the first bicycle race from the town of Grafton on the East Coast to the town of Inverell on the Northern Tablelands. In 2002, forest fires were burning in the Gibraltar Ranges. In late 2007, two prison escapees were last spotted near the ranges and the police were looking for them. In October 2009, parts of the Gibraltar Range were closed because of the potential for bushfires.
