Coarse grained greyish-brown sample with clasts ranging from small to large in size. Clast shape ranges from angular to rounded. Edge-to-edge grain crushing and rotation structures are very common throughout the sample. Rotation structures can be seen around many of the large clasts. A few necking structures and lineations can also be seen throughout the sample. Although the grain crushing is mainly edge-to-edge, there are also many examples of grains that have been crushed into one another.

Coarse grained greyish brown sediment with clasts ranging from small to large. The majority of the sample contains small to medium sized clasts. Clast shape ranges from angular to sub-rounded. Edge-to-edge grain crushing and rotation structures are the most prevalent micro-structures in the sample. Many crushed grains can also be seen, along with lineations and occasional necking structures.

Coarse grained, greyish brown sediment with clasts ranging from small to medium in size. The clast shape ranges from sub-angular to rounded. Lineations are abundant throughout the sample and can mostly be seen with smaller grains. Some rotation structures can also be seen in this sample. Minor amounts of grain crushing/stacking can be seen.

Dark brown sediment with clasts ranging from small to large. The sample is mostly made up of large clasts. Clast shape ranges from angular to sub-angular. Necking structures are common throughout this sample and can mainly be seen between larger aggregates. Edge-to-edge grain crushing, crushed grains, and some lineations can also be seen.

Dark brown sediment with clasts ranging from small to large in size. Clast shape ranges from angular to sub-rounded. The main domain mainly contains larger aggregates. There is one domain inclusion in this sample. It mainly contains small and medium sized clasts, and contains many lineations. Necking structures can be commonly seen in the main domain between larger aggregates. This sample also contains many elongated clasts and inclusions of clay material.
