Processed to 5626 feet, another sedimentary unit

Today we boxed up rock core to a depth of 5626 ft, 100 ft deeper than yesterday.  At this depth, if the rock drills well, this is about the maximum possible recovery in a single day. 
Above is a photo of another sedimentary unit, lately the drilling has recovered one interval of sedimentary rock each day.  This unit contains two large clasts in a finer-grained matrix at its top and middle portions, and then fine sediment at its base that shows bedding and cross bedding.  Note the presence of a variety of clast types in this unit, as well as green and white secondary materials.
