Here is a quick picture of one of the analyses I'm doing on the samples I brought back from the Mara. The different tubes have soil samples for different parts of the Mara catchment. I'm trying to determine the relative amounts of clay, silt, and sand in each catchment. There are only 16 tubes in the picture but I have over 120 samples! The color of each tube really doesn't have anything to do with this specific analysis but I think that it was pretty interesting...the distinct colors from different portions of the catchment.
