Pup Creek
Pup Creek holds the tallest waterfall in the area, Pup Creek Falls. It can be accessed by hiking the Clackamas River trail ~4 miles to it. Upstream though, Pup Creek has many other falls along its path. I descended the whole creek back on 3/23/2010 and documented these falls. I'll start the list at Pup Creek Falls and work upstream.
