There are lots of useful reference links at the beginning of this (and every) thread, but I found this to be on of the most handy:

It has a link to an active google map, and scrolling down below that, about 30 minutes of aerial footage taken the day of the search. If you are having trouble visualizing the lay of the land, or the scale and distances of this case, this one link can be very handy.
Open Google maps to Delphi, Indiana.

You can now zoom in and out on the map, and drag and drop it to zoom in on different areas. Then, going back to the original tab (the news story), watch the video. As you do, there are spots when it stops or goes black- don't close the window, as it will start playing again (and I don't know if this was an issue in the actual chopper footage, or just my internet connection buffering.)
So, while you're watching the video, you can switch back and forth to the google map and really get your bearings. The video was taken at midday during the height of the search, so there is good lighting, they repeatedly circle and zoom and out on the entire area, and if you look at the roads and landmarks (cemetery, creek) you should really (in your mind) start to be able to overlay the labelled map with what you're seeing from the air. And you can also see the type and density of vegetation, height and scale of Monon High Bridge, and steepness of the hills. And you'll see how the trail area is surrounded by farms and residential homes, and probably quite familiar to people living in the area, who like to get out and bushwhack (like these sweet girls.)
I hope these comments are helpful to someone. Apologies if I've over-simplified it, sound redundant, or everybody's already seen this, but I know different folks have different gifts (or not) for map-reading and orienting themselves. Just trying to help. jmo
