this movie is important to those of us interested in western history because it makes use of authentic techniques in its production. the scenes of the wagon train are particularly authentic while so far as i know and it contains the only scenes ever filmed illustrating the techniques for river crossings at a bluff. the horses and mules have to be lowered to the river level and the wagons let down by ropes and pulleys. the scene is such that i could watch it over and again just trying to get a feel for what a crossing was like. and the early travelers did it time and time again while crossing the country. melodrama aside and this picture is as authentic in dress and style as they come and worth watching for that alone.
