How to create geometric landscape element like this?

[SIO]

I want to create landscaping elements such as the topography in the photo using only Rhino 7 or using grasshopper. Modeling one by one is very annoying… If you have any good ideas, please share…!!

It is a mesh-> Subd-> Brep workflow.

Thank you! But do I need to get a specific plug-in?
