Dave,
My old brain just has a hard time with this new technology. I went to the page you indicated, and found Map Tech was the provider or maps of my area. Unfortunately, none of the hyperlinks appear in those map listings. I'm still lost.

By the way, I'm using Dragon to write this reply.

Steve,

I replicated the process.

Go to the following site and click on the blue button near the bottom of the page. That will download a KML file.

http://www.gelib.com...raphic-maps.htm


With Google Earth open, double click on the downloaded file (its name is historic-topographic-maps.kml).

That should create an entry in your Places list (in the panel on the left of the Google Earth window) named Historic topographic Maps. Clicking on the check box next to that entry will bring up historic topos for much of the country.

Go to the area in Maryland you want and select the dot in the middle of the box that overlays that area. That will bring up the topo. The slider in the panel on the left will adjust opacity.

I don't know where your mention of Map Tech comes into this.

I hope this helps.

I'm not using Dragon, but maybe I should. I type at hunt and peck speed.

Dave,
I'm still not getting the option of USGS map dates on Google Earth.

Steve,

I'm not sure what you mean by "dates." Can you be more specific?

Edited: Does "Historic Topographical Maps" appear in the left panel under "My Places" in "Places?" If not we need to go back to the KML file process. If it does appear, then click on the round button next to "Historic...."

Dave,
I've got the Historic Topos in my places but I don't see anyway to choose a specific date.

Steve,

No can do....as regards choosing different dates. You are stuck with the USGS topo maps they scanned. Sometimes that is more than one, but if I recall, the area we are discussing has only one scanned, and it was from the late 1800's. None the less, it might shed some light on the road section you discovered.

Incidentally, there is another site that provides lots of historic maps with overlays which you have probably already used:

Thanks Dave. I don't know if I've listed this before but DavidRumsey.com has a zillion maps and there all free and downloadable.

On Friday, I drove the section of Braddock Road that Steve's talking about here. I found one culvert but didn't seriously look for the other or the road section. Some comments and a picture similar to the one Steve posted is here. The coordinates I got for this culvert are: N 39 38.411 W 78 49.098.

I had no idea I'd be in the area until Thursday afternoon. I did make an 11th hour attempt to reach Steve but it just wasn't going to happen this trip.

Denny,
I liked your National Road trip report. I just wish I could have pointed out some more points of interest.
