main lake points are where you see the land come out to a "point" when you fish those the point usually extends a bit into the lake underwater and whats what people mean when they are fishing "points"

"Humps on the other hand cannot be seen just looking at the lake. Get yourself a good graph and a navionics chip if it is compatable, all the humps on any kind of map looks like circles with more circles marked by the contour lines. a hump can be in 20 ft of water and the top of the hump could be at 12 ft. these usually hold a lot of fish, especially in the summer when the fish are shallow early and theyll go to the nearest deep water.

hope this helps! if i do a little digging once im off work i could find a pic from my HB of a hump
