What is gravel made up of?
Gravel is made by crushing rock and sorting the result into different sizes, generally by screening. Your pea gravel is one of the screening products.

A gravel producer would choose his process according to need. In many parts of the country, merely sorting the river gravels will be a suitable process - provided the source rocks are themselves suitable.
