gimp edge detect

I took some cool pictures of the mountains but where the sun was made
everything dark. I lightened everything but if I lighten it more the sky
becomes bleached. I know GIMP used to have an edge detect select but I
can't find it . What I want to do is select the mountains and everything
below it and lighten only that. How do I do it?
