Calcite rafts?

[raft_hunter]

I am a researcher studying calcite rafts. As part of my project, I am doing an inventory of all locations worldwide where rafts have been found. So far, most of the locations I have found documented are in the United States, Mexico, Spain, and Australia. Where have you seen calcite rafts?

Calcite rafts look like a thin white or off-white film that covers the water table.
