clearance cairn การใช้

• Some clearance cairns are linear in form.
• Agricultural and clearance cairns are sometimes located on slopes, whilst burial cairns rarely are.
• Bog-wood is often removed from fields etc . and placed in clearance cairns.
• Clearance cairn material is often heterogeneous, typically consisting of both edged and rounded small stones, sometimes mixed with sand, clay or silt, lifted from the field nearby.
• The inclusion of clearance cairns at the site is usually taken as an indication of clearance in advance of arable farming, but the Crawley Edge field unusually includes a barrow cremation mound among the cairns.
• Natural deposits such as so called'clitter agglomerates', morains can also on occasion look rather similar to groups of clearance cairns, but their context, position and regular form usually betrays their true origins.
• The "'Crawley Edge Cairns "'are a series of forty-two Bronze Age round barrows, cairns and clearance cairns located in a field in Crawleyside, near Stanhope, County Durham, England.
• In general round barrows are larger, more regular, and may contain visible traces of a cist or kerb; stone hut circles have distinct entrances; ring cairns have a hollow centre; and burnt mounds contain a high proportion of fire-crazed stones of rather smaller size than appear in the average clearance cairns within cairnfields.
• The Isle has a long history of habitation, for example a survey of the ground between the Isle village and Saint Ninian's Chapel revealed Clearance cairns and cultivation furrows, as well as the remains of a rectangular building occupying the crest of the low hill immediately to the west of the chapel, with possible steps leading downhill towards the east.
