Hegarty, C., Knight, S. and Sims, R., 2019-2020, The South Devon Coast to Dartmoor Aerial Investigation and Mapping Survey. Area 2, Avon Valley to Plymouth (AI&M, formerly NMP) (Interpretation). SDV362982.
Pits are visible on aerial photographs of 1955 to 1969 as oval or circular earthworks between 2 and 4m across the west-facing slopes towards the east of Crownhill Down. A crescent of upcast spoil is visible on the downslope edge of most pits.
The pits display a pronounced north-north-east to south-south-west alignment. Three are widely distributed in a row over circa 150m from circa SX57095926 to SX57015914. Five are closely clustered at circa SX56985908.
The pits are interpreted as the remains of prospecting pits of probable medieval to post-medieval date, the north-north-east to south-south-west alignment probably intended to identify the extent of buried tin deposits.
The pits have been destroyed by modern open cast mining.
