Can we alter the forward modelling so that there is a specified halfspace below the layers. Also: in the 1D instead of `t` for thickness, do you think we could go with `layer_thicknesses` ? as the parameter name or `thicknesses` ? ---

Thanks @doug! I agree on the name change. We have an issue going to track changes that we should be making in SimPEG based on the GWB use-case here: [https://github.com/simpeg/simpeg/issues/838](https://github.com/simpeg/simpeg/issues/838) ---

This is implemented. ---
