it is my understanding that a saddle is a low point on a ridge connecting 2 drainage's.

Not sure what areas you are looking at, but I try to get on a high vantage point and glass cuts and clearings early and late.
Also,With scouting Elk in Western Washington, sometimes it is more about locating sign, than actually seeing Elk.
If you can drive the area, look along sides of road for trails, park and get out and walk a short ways in to see if there are any tracks.
Watch for tracks in shoulder of road also.
If there are gates, park at gates and walk in, look for tracks, droppings, trails, etc.,
Once you find an area with good sign, get out a map, or (google earth) and look at where the roads go, and guess at where the trail leads,
look at areas in-between roads, usually these will be drainage's, and hopefully timbered, pay special attention where the head of drainage might cross road, as a lot of times there will be a trail somewhere close.
Also bear in mind that Elk, when feeding, spread out and leave no real "main trail", but when traveling from one spot to another usually are single file, so large trails, that show lots of tracks are usually to/from feeding/bedding areas, look at what direction the majority of tracks are heading to get an idea of which one.
Usually feeding areas are lower than bedding areas, so if you are in,on, or near the top of the ridge, follow the trail to see where it starts to spread out, or seperate, if it is in some timber, you found the bedding area, Dont go too far into bedding area, you might push them out.
Good place to set up a camera, or tree stand/blind is where the trails all meet.
