This photo was taken close by the location of yesterday’s flowstone photo. One feature in this photo that I remain curious about is the small curtain-like calcite growth from the floor that separates the pools of water. My inner geologist and caver don’t have answers for that one so any ideas would be appreciated.
The photo below is of some flowstone in a cave in Mulu. Flowstone is formed from calcite where water flows down a wall. As the water is agitated, it outgasses it’s carbon dioxide leaving behind calcium carbonate, aragonite, gypsum or other minerals that were previously dissolved in the water.
This overhang in the limestone rack face was a significant swift nesting site. Out of harvesting season, there was no one working on this day. Bird’s nest harvesting is a regulated industry and there were signs above the jetty here warning trespassers off. All the bamboo poles you can see here are used by the harvesters to reach the rock ceiling where the swifts build their nests.
