Using Grow on a component... process it 16 times to 'east', incrementing it to 'north' in each step; using the min to max values across half width, incrementing the Z values for each set.
Then copy/mirror all to 'east', then for all of the results you copy/mirror them to 'north', forming the 'mound'...

Thanks, TIG! I did some of them, but I could not make No.2

Another method
As the Plug "Drop" can't intersect with vertices must make this little trick and so don't use "Drop":)
Object of the Extrude Edges is a simple plan as ground
Component circle must have axis at the middle of the circle!
For replace component : Select all components Lines
Menu Component / right click on the Component Circle / Replace Selected

Edit : in fact you can directly make the Spray with the Component Circle on the mountain!
So more speedy!

Thank you so much, Pilou!
