The short answer is that it''s highly unlikely. Although other parts of the world have houseeating sinkholes, Wisconsin''s sinkholes are relatively small. The difference lies in our geology. In Wisconsin, the karst bedrock forms in dolomite, which is much less easily dissolved than the limestone that forms the karst bedrock in Florida.
Sinkholes formed exclusively this way are quite rare, although many sinkholes are in part formed by collapse: chemical weathering in a solution sinkhole may cause a part of the wall to become unsupported and unstable, resulting in collapse. Collapse sinkholes are not rare where limestone is overlain by sandstone.
Mining of coal and metallic minerals in Washington began in the mid to late 1800s. Coal production in Washington hit a high in 2003 with an estimated total production of 6,232,000 short tons, yet production ceased in 2006. Metals mining during the same general time period occurred on both sides of the Cascade divide, but was largely concentrated in the northeastern portion of
