Kitsap Waterfall Survey: "Lower Lost Creek Cascades"

Well over a year since I've last surveyed a waterfall on the Kitsap Peninsula, this was a nice return to form. Several months ago, a friend of mine mentioned to me the existence of a small cascading type waterfall on Lost Creek within publicly accessible land. With me being busy at CWU, it was put on the back burner at the time. Not anymore, This past weekend (2/4/2018) I joined my friend, his son, and their dog and set out to document and photograph this cascade with my own eyes.

Our waterfalling dog companion, Delilah.

A half-mile after it's opening fanfare, Lost Creek encounters another outcrop of Siletzia bedrock which underlies much of the Kitsap Peninsula. The canyon walls and creek bed become lined with a gorgeous blue-green-gray basaltic rock. After tripping over a small rapid in the shadow of a massive fir stump, the creek flows around a bend and slides over a ten-foot drop into a beautifully secluded alcove with a surprisingly deep plunge pool.

The initial 10-foot drop of "Lower Lost Creek Cascades" 

Immediately after this drop, the creek narrows from 10 feet wide to less than 3 feet and careens through a narrow slot cut into the rock, dropping an additional 4 feet in the process. The force of the water tearing through this slot has drilled large circular potholes into the bedrock, making interesting shapes and formations.

Immediately after the main slot, the creek funnels through another bottleneck in the rock in a slide 3 feet high slamming into a jutting rock, taking a 90-degree turn to the left and bouncing over a couple small drops, before leaping over a messy 5-foot rock face. This final drop ends in a rocky alcove similar to the large one upstream. Shortly downstream, "Lower Lost Creek Cascades" terminates in a final small 3-foot slide, bringing the total height to ~25 feet.

The geology of the canyon here is both fascinating and stunning. The underlying grey-blue gabbro rock sets the tone, peppered with red-brown pieces of basalt, and cut with white veins of quartz and calcite. In quieter pools and gravel bars, occasional light colored granite clasts can be found from the overlying glacial debris mantling the entire peninsula. At least at one spot within the cascade, I found evidence for faulting and the intrusion of volcanic andesite dikes 50 million years ago. I plan to write posts on both those geologic stories in the near future.
