Follow Isaac Hull down the intimidating first rapid of the Tumwater Canyon, you can get lost in there pretty easily...

"The first main rapid of Tumwater Canyon, ‘The Wall’ is a puzzle that has bested many paddlers. Nearly a mile long, the rapid has numerous cruxes that may seem obvious when scouting from shore. Once you drop in the waves are blinding and the first few times I ran the rapid I completely mistimed the cruxes. This lap I had the timing dialed but my stern caught and sent me into this monster. No swim zone for sure."
