I think the standard USGS topo maps have 20-foot contour lines and these are useful, but there are still some subtle features that can be left out. Has anyone found any topos with 10-foot contours lines?
I understand that you're never going to beat walking areas on foot, but if there are more detailed maps available, I'd like to start with those.
What's the most detailed topo map you've found?

See my post on Gmap4. Nice topo options and 10-foot intervals.

Tried the site. Still just 20ft intervals in my area

Even toggled to 't4 Topo High'? I see 10 ft near Murray, KY

Part of that area is 10' but a lot of it is 20'.

Yea same problem. Right where you want it, it changes. Where I'm looking 2-3 miles to the east it turns back into 10' intervals.

The contour interval on a USGS topo map varies depending on the terrain. In hilly and mountainous areas USGS topos typically use 20 feet as the contour interval.
By contrast, the following link starts Gmap4 and displays a random spot along the rather flat Minnesota-Dakota border. Here the topo maps use a 5 foot contour interval.

For those "inbetween" areas that aren't mountains and aren't flatland, try looking at the "terrain" view. It seems to highlight the topography and show those subtle points even when you don't have 10' interval lines.
My county GIS mapping site has aerials which you can overlay with topographic lines. These topo lines are 2' intervals. The USGS lines of the same area are 10' intervals. It is worth checking on a county by county basis if a guy wants more topo detail.
