Lake McKenzie, Fraser Island
Lake McKenzie is a ‘perched’ lake, which means it contains only rainwater, no groundwater, is not fed by streams and does not flow to the ocean. The sand and organic matter at the base of the lake form an impervious layer, preventing rainwater from draining away.
The sand here is pure, white silica and is not only beautiful to look at but feels beautifully soft to walk on. The sand acts as a filter, giving the water its clarity and helping to make the water so pure it can support very little life. The blues and greens of the lake are endlessly fascinating.
