Memorable American Pioneer Novels

Novels about American pioneers may not be high on my list to look for and read, but I have read and and been fascinated by a few such stories over the years. One that particularly gripped me and stays in my mind still, although I read it well over 30 years ago, is "Giants in the Earth," by Rolvaag. What I most remember is how vividly it portrayed the bleakness and extreme flatness of the prairies, and how one of the main characters, a woman, became extremely depressed by that bleakness. As I remember the story, she ended by hiding in a trunk that had carried her treasures from back East. For some reason, I can still see that striking image: the flat, flat prairie land and the despairing woman taking refuge in the trunk that was a reminder of home. I was also particularly impressed by Willa Cather's pioneer novels; as I have written here before, I admire Cather's work very much. I list these and other memorable pioneer novels below:
