What to do about a house in Lackawanna County

No soluble bedrock is mapped here, so natural sinkholes are unlikely. Collapses from broken pipes or old mines are a separate risk.

Across 459 square miles, under one square mile of Lackawanna County maps onto soluble rock. With about 216,859 residents (473 per square mile), homes are spread across towns and farmland, and a mapped unit may or may not reach the developed parts. The figures come from 263 map points about 1.3 miles apart, so a pocket smaller than that can be missed or overstated.

Two things to read before deciding: why gypsum and salt move faster than limestone, and how these percentages are measured.
