I came across a couple of features (https://houseprices.io/lab/lidar/map?ref=NY7569166021) about 1km west of Vindolanda (https://houseprices.io/lab/lidar/map?ref=NY7705466352) on a Lidar Map I made.

I assume they're not unknown to science as they're pretty prominent, but then again they're not marked on the Ordnance Survey map as such things tend to be, like the Roman Camps just to their north west for example (http://streetmap.co.uk/grid/375689_566022_120).

Any archaeologists in the house?
