Name of Waterfall

Seymour Peak Falls


A significant basin on the south side of Seymour Peak along the eastern edge of Mount Rainier National Park produces two tributary stream which enter Deer Creek about a half-mile above the Highway 123 bridge. Both streams feature several small waterfalls as they cascade over 1,400 feet down to join Deer Creek, but the majority of these individual falls are considerably difficult to access. The easiest falls to reach - and possibly the largest along either stream - actually lies near the bottom of the valley on the westerly of the two streams, skipping 93 feet down an angular slab of bedrock set amid thick forest. During heavier flows the falls split into two channels for the majority of the drop.
The stream which produces this waterfall is the smaller of the two which flows down from the basin on Seymour Peak, and while its flow will be fairly significant during the snowmelt season, expect the volume to be reduced to just a trickle by the beginning of August in most years (possibly earlier).
