Proudfit Identified 2 Native Village Sites Inside DC - The 2nd Seems to Be Located on the Grounds of The US National Arboretum

In his 1899 article on Ancient Village Sites in Washington, DC, SV Proudfit said there were 2 sites. One was on the former Carroll Estate, the second "southeast of the Reform School on the Ancostia."

Here's how he marked it on his map:

Based on the topographic maps from the late 1800s, there was a hill, Hickey Hill, around that spot. 

Over the years, the land in that area was farmed in various spots, but largely undeveloped until it was bought in the 1920s to create the US. National Arboretum.

Here's how the area from thia 1890s map corresponds to the current map of the US. National Arb.

During the last week, I've been trying to contact the person at the Arboretum, which is part of the Dept of Agriculture, who is responsible for the archaeology done there.  

More details when I get them!

1889 Document Describing the Locations of Indian Villages in DC

"The Aborigines of the District of Columbia and the Lower Potomac" was published in 1889 in Vol 2 of American Anthropologist.  (The title should link to a pdf of the 51 page article.)

It contains the following descriptions of where Natives lived in the area that was to become Washington, DC.

p. 242,
"The principal part of Nacotchtanke seems to have been about due east of the Capitol, for the fields at this point give greater evidence of occupation than at most others, though indications of Indian occupation are to be found at nearly all points of the valley. "

p. 243
"The other village sites located within the old District lines and designated on the map (see Plate V) are (i) " Red Bank," on the west bank of the Anacostia and southeast of the Reform School; (2) the Carroll place in Washington, north of Garfield Park and between First and Second streets S. E...."

Here's part of the map that is included in the 1889 article.
