Smooth fallout


I have tried to make a hill out of a mountain and I am having trouble smoothing out the tip. Any suggestions?

use extrusion, which will create more geometry. then you can add a couple of loop cuts, for even more geometry. then select all relevant vertexes and hit the smooth vertex button on the tool panel a couple of times.

As Modron suggested I would try to select the parts that you want to be the hill and hitting W>Smooth in edit mode a couple of times to smooth it out

also, round off your base vertexes before extruding:
