This past week while excavating our Unit (a 5’ by 5’ measure of restriction), in Annapolis, my group partners and I came upon a very novel and exciting new discovery. The suspicion of an absence of a specific soil type was raised by the evidence of a borderline separating two apparent soil types within a small defined area of the unit. I immediately brought this unexpected find to the attention of others. After slowly and carefully scraping away the surface layers, we were able to conclude that indeed something different was going on here. However, we were not aware yet of the unique formation that was about to be re-brought into view.
By following this border between a very white mix of coal and ash soil and a very rich brown soil we came upon a very distinct horseshoe shaped deviation. The shape was clear yet unusual in appearance. However, its purpose and means of formation was very unclear. As instructed, we began to carefully remove some of the richer brown soil from the interior of the horseshoe to make sure this ash did not reappear inside indicating that the level of stratigraphy had a burrow in it in this location. In the search for this soil we came upon a notable amount of large bricks that were appearing within this portion of the unit. Large bricks were also observed within this same level on the exterior west side of the horseshoe but their occurrences were not so dense and possibly unrelated. In the continuation of the excavation past this ash layer we came upon even more bricks, all within this same limited area.
