Sedimentary
Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution. Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, sediment was formed by weathering and erosion in a source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers
Stratification
STRATIFICATION refers to the way sediment layers are stacked over each other.
This is what GRADED-BEDDING looks like
CROSS-BEDDING is a feature that occurs at various scales, and is observed in conglomerates and sandstones. It reflects the transport of gravel and sand by currents that flow over the sediment surface (e.g. in a river channel).
RIPPLE MARKS are produced by flowing water or wave action
Side-view of current rippled sandstone (note coin for scale). The cross-beds or (more accurately) cross-laminae are inclined to the right, thus the water was flowing from left to right.

Send the following answers to me via email.
- The text "GC5CBXH Shell Knob Overlook" on the first line
- How do the limestone boulders that line the edge compare with the road cut, based on colors do you think the boulders come from this road cut or a different location?
- What colors do you see in the road cut?
- Is the road cut a graded or cross bedding type?
- What is the elevation up here?
