Thanks Steve but all that does (Before and after adding to MinHeight) is make a spikey point on the terrian.

I have come up with this:-

radius = radius + (TerrainHeight(terra,x,z));+0.3
For xx=-radius*5 To radius*5
		For zz=-radius*5 To radius*5
 			x1=xx+x
 			z1=zz+z
 			e#=Sqr(xx*xx+zz*zz)
 			
			
			h#=(radius#/10)-(e/Sqr( (radius)*(radius) + (radius)*(radius) ) )
			If h# > TerrainHeight(terra,x1,z1)
 				h1#=-Cos(h*180.0)/2.0+0.5

 			        If h1<0.0 Then h1=0.0 
 			        If h1>1.0 Then h1=1.0 
	 
			
 			ModifyTerrain terra,x1,z1,h1
			End If 
		Next
	Next

Which grows the hill, but when it begins to sprout from the ground its more of a upside down funnel than a hill until it gets half way before forming a nice roll, then when the top of the hill hits the 1.0 ceiling it then expands into a craggy mess!?!

I'll plug away, it'll come eventually, but I was just hoping someone would have something on hand...
