The antiquarian Colt Hoare opened the mound in the 1806,[1] and found areas of black earth that he believed to be the remains of a wooden-structured burial chamber.

[2] A geophysical survey by English Heritage in 1997 found evidence of a possible burial chamber or mortuary cairn inside the barrow, and an arc of post pits at its eastern end.

[3] White Barrow was the first piece of land that the National Trust acquired purely in the interests of archaeological conservation.

The badgers were lured to a new sett outside of the property, and the barrow was covered in chain link fencing to prevent animals from burrowing into it again.

Finds in the badger spoil from the old sett included struck flints, Neolithic and Bronze Age pottery, and part of a red deer antler.
