116 Pit
Pits and holes with distinct steep sides which cannot be shown to scale by symbol 106 (minimum diameter 2m). Minimum depth from the surrounding ground should be 1m. Location is the centre of gravity of the symbol which is orientated to north.
Colour: Brown.

This symbol is oriented to north.
Pits and holes with distinct steep sides which cannot be shown to scale by
symbol 106 (minimum diameter 2m). Pits with any other shape than round
should be shown by contours. Minimum depth from the surrounding ground
should be 1m. Location is the centre of gravity of the symbol which is orientated to north.
Number chaned, line and symbol width altered.
Defined as point symbol 116.0, can be drawn with any drawing tool.
This is a rotatable symbol, it can be rotated with the direction tool and will rotate with the map if the “include symbols” box is checked when the map is turned.
Care when drawing is needed, a click will place the symbol; a click with drag will rotate the symbol in the direction of the drag. To correct this, redraw carefully. Don Scarrott has written a utility that straightens all rotated symbols.
Small steep sided pits of any shape are normally drawn with this symbol, despite the specification.
A steep side hollow or hole.
