A century before Ridgely, there was Boonsboro.
During 1800-1850, Boonsboro was a thriving crossroads village with a church, school, wheelwright shop, and homes. Its leading citizens were the descendants of John Boon, who acquired large landholdings nearby in the late 1700s.
Boonsboro disappeared before 1900. The historic Boon farmhouse vanished suddenly before 2016. Only the family burial plot remains.
Maps, aerial photos, and a CRH site visit in 2009 tell the story.

Apparently to make way for center-pivot irrigation:
I created a map app where you can compare hi-res USGS topo maps of the Choptank River watershed for different time frames, 1898-1944.
I did it by downloading KMZ files using the USGS TopoView app and publishing them on my own web server. Then adding the URLs to my map app. So easy, you can do it yourself. Heh. I’m sure you’ll want to read details here about the map scales, dates, and metadata.
To see all the layers for all the years, you have to view the larger map app. No time? Just zoom in with this map that shows only 1904-1918. You’ll get the idea. (Yeh, that a KMZ service can be slow.)
Mapper Eric Fischer has created the most detailed tweet map ever. Six billion tweets over 3.5 years – worldwide:
What does the map look like closer to home? Zoom in here and look around:
Zoomed out, it looks like a population density map. Like a census map but with a bias toward showing population segments more likely to be engaged with social media:
Zooming in, we see other patterns and try to understand their meaning. Near Denton, the local hotspots for tweeters are North Caroline High School (upper left) and McDonald’s near MD 404 (lower right). The NCHS hotspot is easy to interprist: a population more likely to be active in social media:
But why are tweets coming from farm fields? Tractor and harvester operators are tweeting while they plow furrows or harvest soybeans?
And why are all these tweets coming from the middle of the Choptank River and from the marshes north of Denton and the MD 404 bridge? Waterfowl hunters? Seems unlikely. Bad geolocations in the Twitter data are always possible. But why scattered here?
And, of course, you have to wonder about all those tweets along Routes 404 and 50. Those just passengers tweeting, right? Can’t be drivers !

The Old Harford Town Maritime Center (OHTMC) in West Denton is no more. But OHTMC’s legacy continues.
Choptank River Heritage sites were first catalogued by OHTMC and published in two volumes:
Maryland’s Upper Choptank River and Tuckahoe River Cultural Resource Inventory (1999)
Lower Choptank River Cultural Resource Inventory (2002)
These studies were funded by the Maryland Historical Trust. They identify many types of historic sites and structures, including:
- canneries, and
- sunken vessels
Since the inventories were published, Choptank River Heritage (CRH) continues the work of OHTMC by publishing historic maps, site descriptions, and stories of people and places of the Choptank River watershed.
If change was inevitable,
so was the map that shows it.

The U.S. Geological Survey (USGS) started printing beautiful paper maps of the American West in the 1860s. Then worked its way east until it finally got to:

Take to the highway, won’t you lend me your name?
Your way and my way seem to be one and the same.
Mamma don’t understand it. She wants to know where I’ve been.
I have to be some kind of natural born fool to want to pass that way again.
But you know I can feel it, yeah-yeah, on a country road.
Walk on down, walk on down,
walk on down a country road.
In 1875, all roads in Caroline County were dirt. Most were crooked.

Zoom in. Then use the transparency slider and background map changer at upper right.
