Thus, a brown, 5-foot-thick limestone, with chert nodules, an upper wavy surface and a lower planar surface can be recognized by this association of physical characters. Wherever this limestone layer crops out at the earth's surface, you can say "Aha, this is the same layer as I saw at such-and-such a place!"

How to Identify an Indian Tool Made From Rock Our

2017-4-12  Identifying Indian tools made from rock is moderately easy if you know what you're looking for. Indian artifacts may be strewn where there was once a settlement. Arrowheads and bird points may be found at vantage points, such as cliff tops and bluffs, although only fragments or shards of these primitive tools may

Millions of years ago Indiana was covered by a shallow sea. It is believed that geodes began as crystals that were covered in silica. The initial crystals dissolved and were replaced by other minerals, creating the geodes known today. Most of the geodes in Indiana are in areas that were not covered by glaciers during
