Eventually, European explorers encountered the strategic confluence where the Allegheny and Monongahela Rivers meet to form the Ohio, which leads to the Mississippi River.

The Neill Log House is a historic log cabin in Schenley Park in Pittsburgh, Pennsylvania, United States. It was built during the second half of the 18th century and has been most commonly attributed to Robert Neill (Neal), with an estimated construction date possibly anywhere from 1765 to 1795. This estimate is based on architectural evidence as well as the large increase in value of the land during Neill's period of ownership which would indicate he made substantial improvements. However, the earlier date of 1765 claimed in some sources, would associate the building with an earlier landowner, Ambrose Newton. In 2024, a dendrochronology study determined that the beam over the fireplace, believed to be original to the house's construction, was dated to be from 1795, which was the date that Robert Neal sold the cabin to John Reed. It is known by records that Robert Neal purchased the land in 1779 and sold the cabin and land in 1795. Extrapolation of the known dates of Robert Neal's purchase and date the property was sold and the large increase in value during Robert Neal's ownership indicating he made substantial improvements likely mean it may have been built by him between 1779-1794.
