- A thousand years ago the area around the confluence of Trout Brook and Phalen Brook near the Mississippi River was a marshy flood plain. By the early 1900s, the entire delta had been expanded by filling and became an industrial railroad corridor. As rail use decreased in the 1970s, the land was largely abandoned and buildings and tracks were removed.
- Denny Camp Falls (waterfallsnorthwest.com)
Denny Camp Falls is likely the largest of a number of small waterfalls found both above and below Franklin Falls along the South Fork Snoqualmie River. Conveniently this waterfall happens to be situated almost immediately to a road and features quite easy access (though clear views require a bit of less-than-easy scrambling). The river here constricts between narrow gorge walls and plunges 27 feet into a small bowl flanked by dark mossy cliffs. Because of the constricted gorge walls, the Franklin Falls trail which passes the falls has to divert almost quite literally onto Denny Creek Road #58, and this fortunately facilitates quick in-and-out access for those looking to visit several waterfalls in the area in one day.
