This is a collection of well cores from the state of Indiana with a few from surrounding states. There are 1,084 cores filed to date at the Indiana Geological Survey. This translates into approximately 34,098 boxes and 202,744 feet of core in the building, which is at capacity. The core in this collection is variable with different diameters. Some are filed whole, halved, and quartered. Some of the cores are sawed which gives a very smooth surface as opposed to a raw surface when the core is split.
