The valley is most distinct in central Chester County, although traces of it can be followed almost the entire distance between the Delaware and Susquehanna rivers. Valley Creek flows along the base of eastern Great Valley, towards the Schuylkill River. A second creek, also named Valley Creek, flows westward from Frazer into the East Branch Brandywine Creek. Beaver Creek flows eastward along the northern side of the valley from around Thorndale into the East Branch Brandywine Creek. Multiple branches of both the Brandywine and Octoraro creeks cross the valley.

The Frazer Diner, in Chester County, Pennsylvania, was built by the Jerry O'Mahony Diner Company and is now the only remaining example of an unaltered mid-1930s streamline modern O'Mahoney diner. Its original features include the monitor roof, half-moon windows, and porcelian-enameled base. The diner was split lengthwise and originally shipped to Paoli, Pennsylvania and operated as the Paoli Diner.Originally manufactured in 1935 (though some sites reference 1929), it was purchased by Frances and Sylvester Cavalati in 1957 and moved to its present location at 189 Lancaster Avenue, Frazer, Pennsylvania in East Whiteland Township. In 1972, while retaining ownership, they leased it to others to operate and the name was changed to the Frazer Diner.Around 1983, the diner was leased to Tam Nguyen and his wife Hao (law school graduate and nurse, respectively) who had fled communism in Vietnam and moved to the Main Line in 1980. They operated it as the Linh Diner, specializing in Vietnamese-Chinese food, and it became a regular lunch stop for nearby high-tech companies in the Great Valley. After five years building a successful business, they were running out of space and looking to move to a new location that was to be built as part of a new shopping center nearby. Before that happened, the Cavalati's served the Nguyens an eviction notice, and noted there was a buyer who wanted to move the diner to Hollywood.The Nguyens did eventually open the Linh Restaurant nearby, but the diner was not moved to California, and eventually re-opened, once again as the Frazer Diner.

Duffy's Cut is the name given to a stretch of railroad tracks about 30 miles (48 km) west of Philadelphia, Pennsylvania, originally built for the Philadelphia and Columbia Railroad in the summer and fall of 1832. The line later became part of the Pennsylvania Railroad's Main Line. Railroad contractor Philip Duffy hired 57 Irish immigrants to lay this line through the area's densely wooded hills and ravines. The workers came to Philadelphia from the Ulster counties of Donegal, Tyrone and Londonderry to work in Pennsylvania's nascent railroad industry. While their fates are unclear, a theory based on a record from a railroad archive suggests all 57 died of cholera during the second cholera pandemic. The remains of seven have been discovered at the site, and forensic evidence suggests that some may have been murdered, perhaps due to fear of contagion as the pandemic spanned several continents over many years. While this has become the most popular theory, a coroner who studied the bones believes the alleged bullet holes and injuries were actually due to natural decomposition and post-mortem damage. The site is located in East Whiteland Township, Pennsylvania, 1,500 feet (460 m) northeast of the intersection of King Road and Sugartown Road, where a Pennsylvania state historical marker has been placed.
