Stone to Build a State

Indiana is fortunate to have abundant geologic resources and at the IGS scientists conduct research to learn how best to use them. Crushed stone for building roads, raw materials for making cement, dimension stone for architectural uses, shale for making bricks, and prosaic sand and gravel for all sorts of uses—we study these to promote the wise use of our natural heritage.
