Alamo Archaeology Church Preservation - August 15

August 15, 2025

Archaeological investigations continued at the Alamo Church last week. Archaeologists were active in EUs 35, 37, and 44.

In EU-35 and EU-37, archaeologists completed excavation at approximately 150 cm below surface. Once excavation was complete, final documentation commenced. Archaeologists mapped all wall profiles, took multiple photographs, captured elevation and GPS points, and did a 3D scan of the unit. Artifacts from these units are still being processed.

Archaeologists started a new unit last week, EU-44. This unit is located near the Alamo Church exit and adjacent to the interpretive sacristy walls. Archaeologists reached an approximate depth of 60 cm below surface by the end of the week. This unit is already characterized by multiple construction-related activities. Two modern PVC conduits were exposed and an abandoned metal pipe was also encountered. The soil deposits are mixed and have a large percentage of sand, indicative of construction fill related to the utility conduits. Artifacts include metal fragments, bottle fragments, and a historic electric insulator fragment.
