The banks, running broadly east to west and ranging from roughly 15 metres to 60 metres in length, dissolve into the surrounding landscape when you try to meet them on their own terms, absorbed by the hollows and undulations of the field they once divided.

The features were recorded during a survey of the Lee Valley area carried out in 1996 and 1997, when aerial photography revealed patterns that fieldwork alone might never have caught. This gap between what the land reveals from above and what it withholds from a person standing in it is not unusual in Irish archaeology. Low earthworks, particularly old field boundaries, can survive for centuries as subtle shifts in terrain, their original form softened by time, ploughing, and the slow movement of soil. The fact that they registered clearly on aerial photographs suggests the banks retain enough integrity to cast shadows or hold moisture differently from the surrounding ground, even if that difference is imperceptible underfoot.
