Gaia Green Glacial Rock Dust is mined from a glacial moraine in Canada, and is the result of thousands of years of piedmont glacial action. As the glaciers travelled from north to south during the last ice age, they picked up rocks containing a range of minerals and trace elements. As the glacier receded at the end of the ice age, it left behind deposits of glacial moraine. These deposits are mined, dried, and screened to be used as a natural soil amendment.
