"Some of the things that helped me get a better grasp of my area are old mining and geologist reports of the area. Some of which talk about how and when the glaciers moved through the area and in which directions, when the mountains uplifted, how to identify which gravel, glacier till, and clay layers are from which time periods, how to identify tertiary channels under those sediment layers, etc, and what types of false and true bedrock there is in the area. "
the above is exactly what I need to research in detail. Thank you for that Blue clay.
