| Harry Moore discussing the geology of Ijams' Mead's Quarry |
Retired state geologist and author Harry Moore led a Geology Walk yesterday afternoon at Ijams for adults and young rock-hounds.
Moore has authored several books about regional and state geology, plus the fossil site at Gray, Tennessee. He also knows the Ijams bedrock and quarries very well having grown-up near the now Ijams' properties. Moore developed his life-long interest in geology in the area. The abandoned quarries were his childhood playground.
Moore discussed the four bedrock layers that underlie Ijams, west to east: 1. Ottosee Shale Formation (gray shaley rock) exposed at Homesite; 2. Chapman Ridge Formation (sandstone with limey matrix); 3. Holston Formation (industrial grade limestone found at quarries sold as Tennessee Marble); 4. Lenoir Formation (crumbly, shaley gray limestone, Toll Creek east to Forks of the River).
Special thanks to Harry Moore and to Alice Ann!
