Mosaic officials say they still don’t know the depth of a sinkhole that opened up at the Mosaic plant near Mulberry last month. The hole opened up in August, but the public did not know about it until WFLA News Channel 8 broke the story. On Monday, Mosaic officials released details about the size of the sinkhole, which ranges between 40 feet, and 150 feet in diameter at its widest point, and approximately 220 feet deep from the top of the gypstack.

Mosaic recently used LIDAR/sonar equipment to measure the sinkhole. LiDAR is a remote sensing technology that uses light in the form of a pulsed laser to provide three-dimensional mapping. This technology expedites the remediation process. “Based on the survey results, the company now has a better understanding of the sinkhole dimensions – which is a critical step in remediating the sinkhole,” Mosaic said in a release. READ MORE
