Welcome to the forum. I'll apologize in advance. This one got a little wordy.
My property is very steep with ridge tops, saddles, benches and ravines. I wont tell you where to hunt but can give you some pointers on how to read a topo and what to look for in such terrain. For starters this type of terrain can be very challenging to hunt. Line of sight is diminished and air currents (scent flow) are not going to follow your weather forecast. Here is what I have found by hunting areas with steep terrain over the last 15 years:
1. the closer the lines on a topo, the steeper the terrain. Ovals and wide circular patterns are the tops of hills. The areas that look like fingers are ridge tops. The wider the finger, the flatter the ridge top. Where ridge tops end (looks like the tip of a finger or thumb) the lines usually tighten up indicating a steep drop in the terrain like this : Air flow can be very unpredictable in these areas.
2. contour lines are all of the squiggly lines on the topo map. The darker lines are marked with elevation numbers. These are called index lines. Here is a good example of how to visualize index lines and elevation: The area between the two humps is a saddle. As mentioned already saddles are good ambush points.
3. Air flow and your scent will flow down hill similar to water anytime the sun has not warmed the upper atmosphere. In other words if your at the top of a ridge and its a cloudy cool or cold day your scent will flow downhill until the sun warms the upper atmosphere and your scent begins to rise or go uphill. This can be the 1st hour of a day or last all day long depending on the weather.
4. The head of a ravine will suck the air flow and your scent down to its bottom like a vaccum regardless of the prevailing wind direction. Areas where 2 or 3 ravines meet are HOTSPOTS. If a deer wants to go from one ridge to either of the other two ridges ridge they will travel through these areas. Also, deer crossing through these areas can scent check huge areas and remain in the cover of the ravine. There is usually one ridge here where the wind "usually" goes uphill. That's where you want to be.
5. Deer like to bed just over the downwind side of a ridge top where they cannot be seen from the top of the ridge. Being on the downwind side allows them to smell whats on top of the ridge behind them and see downhill in front of them. I've never seen a deer bed facing uphill.
6. Benches are great places to hunt when the air currents are flowing downhill. A bench is used to scent check what is above and still have a visual of what is below without being exposed. They also provide an easy travel route as they are usually fairly level.
7. If your in the South your North facing ridges will be thickest. Think cover and food. South facing ridges have the hot sun beating down on them all summer. Any fallen leaves or vegetation dry up and are windblown off of the ridge. North facing slopes will be lush with ferns and wet leaf matter on the ground. Good soil = good food and cover.
8. Hunt near the top of ridges when the air current is flowing up, and hunt the ravines when the air current is flowing down. Sounds simple but it's rarely that easy.
Best of luck to you
