The Bubbler - SA

Located 4km off the Oodnadatta Track about 10km east of Coward Springs within the Wabma Kadarbu Mound Springs Conservation Park. Vehicle access within the park is limited to the entrance road to Blanche Cup and The Bubbler mound springs.

Mound springs are natural outlets for the Great Artesian Basin. Mound springs occur wherever the pressure in the aquifer is able to force water to the surface through cracks in the overlying impermeable rocks. The dramatic fall in pressure at the surface causes chemical changes in the water; magnesium, sodium and calcium carbonates are precipitated at the outlet and slowly build up to form hillocks usually several metres high.

The Bubbler is named for the occurance of erruptions of gas that disturb the otherwise tranquil pool over its outlet. The wetlands created by the spring's overflow at the Bubbler and Blanche Cup provide habitat to a variety of waterbirds.

Take the time to also take a visit to the extinct mound spring of Hamilton Hill also in this area.
