History

The town was officially gazetted in 1893 following the discovery of gold in the area in 1890 by a prospector named Francis Jenkins who is remembered by the name of the town's main street.[2] The name Marble Bar was derived from a nearby jasper bar mistaken for Marble and now known as Marble Bar, which runs across the bed of the Coongan River.

In 1891 the town boasted a population in excess of 5,000 as it experienced a rush on the goldfields.[3]

By 1895 the town had its Government offices built; these are now National Trust buildings. Cut from local stone, the buildings still stand today.

Possibly the most famous building in the town is the Ironclad hotel built in the 1890s, constructed of corrugated Iron, and given the name by American miners who were reminded of the Ironclad ships from the United States. In 2006, the Ironclad hotel was listed on the Western Australian register of heritage places.[4]

Several large gold nuggets were discovered as a result of the goldrush. The 333 ounce Little Hero nugget, the 413 ounce Bobby Dazzler and the 332 ounce General Gordon nugget were all found in the goldfields around the town.

During World War II, United States Army Air Forces and Royal Australian Air Force heavy bombers were based 25 kilometres (16 mi) away as the crow flies at Corunna Downs Airfield. Allied airmen from the base attacked Japanese forces far away as Borneo.

It had a railway connecting with Port Hedland up until the early 1950s, which can be seen as a narrow gauge precursor to the network of standard gauge iron-ore railways that have since been created across the Pilbara.

Climate

Marble Bar has an arid climate with very hot summers and mild to warm winters. Most of the annual rainfall occurs in the summer. The town set a world record of most consecutive days of 100 °F (37.8 °C) or above, during a period of 160 days from 31 October 1923 to 7 April 1924.[5]

During December and January, temperatures in excess of 45 °C (113 °F) are common, and the average maximum temperature exceeds normal human body temperature for 6 months each year. Rainfall mostly occurs in the summer months. Marble Bar receives 159.6 clear days annually. Dewpoint in the summers is between 10 and 15 °C (50 and 59 °F).

North Pole

An ironically named locality nearby is known as North Pole (21° 05' S. 119° 22' E.), no doubt for its heat. It is the location of rock formations considered to have evidence that puts the origin of life on earth back to 3,400–3,500 Warrawoona Group) being formed by evaporation and a dome structure from the North Pole chert (also Warrawoona Group) being formed by soft-sediment deformation.[17][18]
