It looks like you are using a Shadow Mapped light with a low map setting.

Try either drastically increasing the shadow map size or switch the light to a Raytraced Shadow.

Good luck, let me know if this works.

I wouldn't use an onmi light, it casts 6 times as many shadows as a spotlight.

You could try adjusting the "ambient" light to brighten up the dark spots.

Making the ground ( Mountain ) not cast shadows might not be something you want to do, as it will not cast a shadow on the rest of the ground.

Keep on working with it.
