From the layman's viewpoint, this is what is seen:  huge granite boulders along the river and lake shores and in the tributaries, as well as glacial litter deposits.  River banks of slate rock ledges, iron rock, gravel, sand, and mud at low tide.  Very coarse gravel and then a layer of extremely fine sand is not uncommon.

More officially, our area has an iron ore potential, sills, slate, and metasantstone, dating back 40 million years.  There are fossils and fire clay.  A walk on the river bottom at low tide can prove interesting!

Granite rock is very plentiful and served early Bear River very well, both for foundations and grave stones.  Both can still be seen today.

Gold was found in small quantities!
