Pearl Falls is one of the highest waterfalls in Mount Rainier National Park in the U.S. state of Washington.

The columnar basalt was likely formed by cooled eruptions of Mount Rainier, which is a stratovolcano.

Near the base, it crashes onto a rock ledge and fans out towards the left bank, before dropping again vertically onto a pile of talus and cascading downwards.

Access to the falls is extremely difficult, requiring at least two days to reach safely on foot.

[5] Pearl Falls was named in 1912 by Albert Henry Barnes, a photographer from Tacoma.
