'The Bubbler' in the Wabma Kadarbu Mound Spring Conservation Park and part of the Lake Eyre Supergroup, has the highest discharge of any individual spring in the Lake Eyre Supergroup. The spring is called 'The Bubbler' because it has been known to 'erupt' every so often. Previously it was reputed to rise 3-4 feet into the air, before current extractions rates of water.
Whilst some springs lie at ground level, many springs have the distinctive mound shape and are known as 'mound springs'. Mound springs are formed by the mineralised material coming to the surface with the ancient artesian water. The height of the mounds vary, depending on a number of factors such as water discharge rate and concentration of minerals. In Wabma Kadarbu Mound Spring Conservation Park, the mound springs vary in size and height, with Blanche Cup being about 5 metres high and a width of some 25 metres.
