I can't add valleys to my terrain?
Hi, I can't add valleys to my terrain. I think its because at default the height is set to the lowest value or something. I googled a solution and it gave me a script but it's code is now obsolete.
All other posts talk about the earlier 'Terrain' tab at the top which we no longer have and I'm really struggling for answers. How do I lower my terrain?

You're right - you can't lower a newly-instantiated terrain - it's created at zero height.
So, first, raise the entire terrain up. ("Paint height", set an appropriate height, say 100, then click Flatten) 
Then, go to the Raise Lower terrain tab, hold down shift, and paint to lower the terrain. 
Anything that refers to a Terrain tab is very out-of-date (i.e. Unity 3.x) - all terrain settings have been in the inspector pane for ages now.
Thank you so much for your help, the use of images and clear instruction is greatly appreciated.
