2. Gunpowder River Marker
I have to say this is the most explicitly racist marker I have encountered thus far in Maryland. There isn't a date for the marker but based on style and material I want to guess 1930s to 1950s. I intend to research both the marker and "legend" and will update if I find anything. Note: as an amateur local historian one thing I have found odd is the virtual absence of native tribes in the Baltimore city and county region in the colonial era. This is evidenced both by contemporary accounts and toponomy. It doubles my skepticism about the marker's veracity even as folklore.
