Sand blows are major sand formations occurring on the island, resulting from the gradual action by which sand shifts across the island. Coloured sands occuring on the island are another attraction, consisting of sands compacted and bonded by silt and clay to a hard consistency. Where they are exposed they give the island some of its most magnificent scenery. Lake Wabby, pictured here, is being reduced in size due to a massive sand blow that advances around three metres a year. Others have reported catfish as large as 3 feet long gathering in the depths.
Giant freshwater tortoises too inhabit the lake, which is the deepest on the island.
Near Rainbow Gorge, the Kirrar sandblow looks like a small desert, and here, in the middle of all this sand, there is a beautiful spring, running for about 20 - 30 metres to a little waterfall before disappearing back into the sand. All rights reserved.
