What is pea 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. There are several rock-crushing systems, and these give a different range of sizes in the product. There are hammer mills, rod mills, 'rod and cone' mills, and so on. 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.

Where do you find flint?
You can find flint by digging up gravel. There is a chance you will get a piece of flint from digging up one block of gravel, though most of the time you only get gravel. Gravel can be found in caves, by a river bank, and the bottom of the ocean (good luck digging up gravel down there!). Gravel really doesn't have much use, though it is known for making "gravel elevators." Flint, however, is used to make arrows for bows and arrows.
