Normally Pilchuck Falls is a segmented waterfall with one main drop and a couple smaller ones.  However, when the river is running high, it can be one huge block waterfall around 60' wide.   Here's a video of a kayaker running the falls to give you an idea of what it looks like in high water.   The trail down to the falls is pretty steep and difficult.  During the summer, people jump from the cliffs next to the falls into a very deep pool at the bottom.
