Went yesterday June 27, 2013. Lower Falls had several logs on right side center but still amazing. Did not do hike as described in book but went to Quartz bridge anyway and walked out over rocks and trees after seeing not so crowded lower falls. Next time will plan for more time to see upper and middle. Its a 3 hour drive from Milwaukie, OR!
P.S. Officials there ticketing vehicles without parking permits! Had my northwest pass. (-:
