The thoughtful team from SUMMIT LIABILITY SOLUTIONS, INC. in Calgary are some of the most professional geoscientists anywhere. The classroom training for TAKING THE MYSTERY OUT OF THE SUBSURFACE was well received, and the excellent questions and discussions about different soil classification systems was among the most important ever.
Canada has regulations about land reclamation that demand the Canadian Soil Texturing Classification is used which is appropriate since it's applied only to the top 1.0 meter and to the A-Horizon and the B-Horizon. The Canadian system is similar to the USDA Texture Triangle, but it's not exactly the same.
For the classroom training, we normally teach the Unified Soil Classification System since it the most widely used soil classification system in the world, and is the standard for hydrogeologic and environmental projects that have an engineering component.
But in Canada, the Modified USCS is often used. The Canadian Modified USCS included nuances with both the fine-grained classifications (addition of the 'INTERMEDIATE CLAY (CI)" and the coarse-grained classification with a subtle difference in percentages of fine-grained fractions for Group Names. It's still super simple to learn soil classifications because the symmetry is maintained with the Canadian system.
I tip my hat in Thanks and Respect to the great people from SUMMIT LIABILITY SOLUTIONS, INC.
