Figure 13.7 Major Limestone and Karst Areas of the World Distribution of the major limestone and
karst areas of the world. Karst topography develops largely by groundwater erosion in areas underlain
by soluble rocks.
Figure 13.8 Sinkholes
a This sinkhole formed on May 8 and 9, 1981, in Winter Park,
Florida. It formed in previously dissolved limestone following a drop
in the water table. The 100-m-wide, 35-m-deep sinkhole destroyed a
house, numerous cars, and a municipal swimming pool.
b A small sinkhole in Montana, now occupied by a lake. The water
enters the lake from a hot spring so it remains warm year-round. In
fact, tropical fi sh have been introduced into the lake and thus live in
an otherwise inhospitable climate.
