It is famous for its opalescence and a number of opalescent areas around the city, as well as the "yowah nut", a typical species of the area. This area was first rented to prospective colonists in 1883 and since the discovery of the first optal plots, the area has been a key business in the area.

Yowah Opera is famous the whole time for its wonderful colors and splendid designs, all of which were produced by Mother Nature, with a large part of the formations being formed by it. Yowah contains all types of opaque material, but the "Distinctive Yowah Nut" is a significant one. The Yowah has a general store, fuel, post office, primary school, caravan park and is run by Royal Flying Doctor Clinics.

Yowahopalfeld, which incorporates Black Gate, the most southern opaque quarrying center in the west of Queensland, is a favourite with visitors and fossil dealers as it is easily accessible from the major highways and has stores, petrol, telephone, a trailer fleet and a constant source of fresh swill.
At Quilpie, go 110 km through Toompine to the Eulo/Yowah turnoff.
Take a turn to your right and drive along this largely unpaved street for approx. 56 km until the turn-off to Yowah, and proceed for another 23 km as described above. There' lodgings in Yowah City. One of the characteristics of the Yowah is the presence of valuable opals in silicate iron stone tubers, commonly known as yowah nuts.
They have a diameter of approx. 5mm to 200mm, are spherically or elliptically shaped and alternately have concentrical light and darkbrown pebble or strip. Sometimes there is a core of valuable opaque, which is the primary resource of the gemstone. Hazelnuts are located in strata (150-600 mm thick) at a depth of up to 20 metres in a ferrous sand-stone and are often associated with claystone remains or ceramic beads.
There is a major stratum near the point of collision between the sandstones and the claystones below them, but there may also be dispersed lumps and in some cases a second one. The walnut strip was not found in some pits, but the limestone at its point of intersection with the clay stone was more ferrous and was partially opalized and thus made into a harder strip, which also included opals in the shape of stitches and canes.
Most of the fossil area to the east has always been a favourite place for visitors to sprinkle or pasta pieces of opals or iron stones from the ground or at low depths. It seems that the major walnut belt has been uncovered on the top, so that a bed of debris of broken iron-stone walnut remains cover the top to a thickness of about 600 mm.
The detection of splinters of opal or die parts when excavating this rock is relatively simple with some work. Multiple mine entitlements and lease agreements are currently located within the fossiking area and are shown on the Yowah fossiking card (PDF, 374KB); they may not be submitted without permissio n of the owners.
