Figure F25. Images of textural and compositional variations of the mud clast gravels. A. Gravel of well-rounded pebble-size mud clasts (interval 338-C0022B-38X-4, 115.5–132.5 cm). Possible cobble of brownish silty clay is labeled. Arrows = compactional deformation of a clast that suggests the presence of contrasting hardness among the gravel population. B. Granule-size mud clast gravel (interval 338-C0022B-38X-2, 56–62 cm) [top of Unit II]). C. Mud clast pebbles distributed along possible erosion surfaces (dashed yellow lines; possible lag layers) (interval 338-C0022B-38X-5, 8–19 cm).
