trial trenches

Trial trenches are carefully dug, narrow excavations used by archaeologists or engineers to investigate what lies beneath the surface. They help assess the condition, location, and significance of buried features or artifacts without extensive excavation of a large area. By examining the exposed layers and objects in these trenches, professionals can gather valuable information about historical sites, construction projects, or underground utilities, guiding further work and preserving important findings. This method minimizes disruption while providing critical insights into subsurface conditions.
