How do you know which layer formed first in the canyon?

• Where ever the river level is currently shows the first layer

• Older layers are found on the top of all the other layers

• Older layers are found at the bottom since newer layers formed on top of them over time

• Older layers are found at the bottom since the heaviest sediments settle to the bottom first then the next heaviest and so forth.
