Ridges come in many sizes and shapes. When a ridge is a small hight change in a marshy or swampy area, I believe it can be a great funnel.
If the ridge is a knife point, more or less, it may be traveled but as above, maybe mainly at dark hours. If the ridge is a broad top with heavy nut crop and mast on the ground, the whole thing may be used any time of day.
In the summer, I am assuming the shaded side, just below the top is a good bedding area as it is cooler and allows the best protection (sight, smell, non-ease of approach) while in the winter the sunny slope is much preferred as a bedding site. Well, at least up north here.
Ridges can be weird because of wind patterns and eddies.
Animals are, however like us. We TEND to walk on the sidewalk between points A and B. Some will walk on the grass, but most do not. If there is a terrain feature that steers them, it TENDS to be the place they will go.
I used to look at a map of farms in Illinois, river bottom country up arouns Peoria and north and be able to show you where main trails will be.
Just look at the ridges, see where the "fingers" come off the ridges and follow them down. If you can find a place where several "fingers" from several ridges sort of come together, or provide a "connection" of sorts between the ridges, it is almost guaranteed that there will be a well used trail on each. Watch that wind !
