Early this morning we did a tour of the Geike Gorge. It is very beautiful but we have now seen several gorges and I think I am gorged out.
Geikie Gorge is a little different because you can easily see where the level of the water reaches in the wet season. The limestone rock is bleached white by the water, so for about 10 metres above our boat we could see white limestone which then changes to a deep orange colour stained with black. The black is from rain water pouring down in the crevices.The limestone has become carved out by the water and resembles honeycombe and forms small holes, crevices and huge caves, some shapes hanging down into the water resembling icicles. The tiny Fairy Martin birds make an ice-cream cone shaped nest hanging under the rock ledge from mud. These nests get washed away every wet and the birds return to the same spot in the dry and start the labourious process again to rebuild these mud nests, year after year in the same spot.
