atenţie la tipul de rocă În link-ul lui George e vorba despre sinkholes ca fenomene carstice, nu în loess.
Am găsit totuşi sinkholes şi în loess:
Groundwater flow in loess will carry away fine, insoluble mineral particles, and this mechanical separation in loess can be accompanied by solution of mineral particles. This process gives rise to depressions, sinkholes, loess wells, and collapse ravines and is much accelerated by gully erosion.

v. Wikipedia
Crovurile sunt adâncituri de formă circulară sau ușor alungită, formate într-un substrat loessoid datorită acțiunii exercitate de apele freatice.

A sinkhole, also known as a sink, snake hole, swallow hole, swallet, doline, or cenote, is a natural depression or hole in the Earth's surface caused by karst processes — the chemical dissolution of carbonate rocks[1] or suffosion processes[2] for example in sandstone.
