Soil mark
From Wikipedia, the free encyclopedia
Soil marks are differences in soil colour as a result of archaeological features. They can be seen when a ploughed out earthwork has left hard dry material of a former bank and damper wetter material from a former ditch.[1] They can also occur when a feature has cut through the top soil to reveal underlying chalk.
