After further discussion on our topic of bentonite, I would like to look at the volcanic ash layer and make a stratigraphic column of a few layers below and above the bentonite. More research will be conducted to compare what is found at the Lee’s Ferry site and what is found in a neighboring region, as suggested by Jefferson Chang. Samples will be brought back to the lab for analysis after the spring break trip. Based on photos that I have found through research, it appears the layers will exposed very well. Another aspect that I will be focusing on heavily will be the fossils found in the sampling site compared to other regions and the environments.

  1. It’s good to see that you and Katherine found a project that incorporates both your interests. Just from a quick Google I found this USGS paper from 1963 that I found has some nice information in it.

    FYI if you search “bentonite layers: lees ferry” your blog is the first thing found.
