11P is a very long plaza trench that runs from north-to-south from just south of Room 60A and ends roughly even with Salmon's Great Kiva (Room 130W), roughly 35 m to the south. Not unexpectedly, this long trench revealed 18 features, including hearths, trash pits, ash pits, walls, and other features in Salmon's plaza. Thirty-four individual strata were designed during excavation of the trench across Salmon's plaza.
