sinkhole
A hole formed in soluble rock by the action of water, serving to conduct surface water to an underground passage
A depression in the landscape where limestone has been dissolved
A circular, often funnel-shaped depression in the ground that forms when soluble rocks dissolve
A depression in the land surface formed either by collapse of the roof of an underground cavern or channel or by solution of near-surface limestones or similar rocks
Sinkholes occur when earth on the surface collapses into a subterranean cavity that has formed in a limestone bed
A pit like hole in found in areas of karst These features are caused by the weathering of limestone or dolomite by subsurface drainage Also called a sink or doline
A surface depression produced when underlying bedrock (usually limestone) or salt dissolves or when caves collapse
a depression in the Earth's surface caused by dissolving of underlying limestone, salt, or gypsum Drainage is provided through underground channels that may be enlarged by the collapse of a cavern roof
or sink or doline Depression formed as underlying limestone bedrock is dissolved by groundwater. Sinkholes vary greatly in area and depth and may be very large. The two main varieties are those caused by the collapse of a cavern roof, and those caused by the gradual dissolving of rock under a soil mantle. Collapsed sinkholes generally have steep rock sides and may receive streams that then flow underground. Soil-mantled sinkholes are generally shallower; they may become clogged with clay and hold a small lake
A steep-sided depression formed when removal of subsurface embankment or foundation material causes overlying material to collapse into the resulting void Seepage through the limestone foundation at Horsetooth Reservoir has caused sinkholes at the south end of the reservoir near the Swim Beach and also one sinkhole near the upstream face of Horsetooth Dam All sinkholes have been filled and capped
Crater formed when the roof of a cavern collapses; usually found in areas of limestone rock
An opening in the earth created by either natural or man-made subterranean activities For example, if a tunnel fails, it may create a sinkhole
A circular depression in a karst area Its drainage is subterranean, its size measured in meters or tens of meters, and it is commonly funnel-shaped
also called sink. A depressed area in which waste or drainage collects
Strictly, a hole or doline (qv) which acts as a streamsink Unfortunately, the word has become debased by common misuse as a synonym for a doline (qv), especially a collapse doline
{i} depression, low-lying area in which water collects
A closed depression formed either by solution of the surficial bedrock (e g , limestone, gypsum, or salt) or by collapse of underlying caves Complexes of sinkholes in carbonate-rock terrain are the main components of karst topography
a depression in the ground communicating with a subterranean passage (especially in limestone) and formed by solution or by collapse of a cavern roof
A depression in the landscape formed by the collapse of the land surface below which limestone has been dissolved Karst topography has many sinkholes
