Bridge over unnamed stream in Marckworth State Forest- Marckworth Forest (wta.org)
Marckworth Forest offers some wonderful walking among forest, marshes, and rumpled rocky hills, as long as you’re ok doing your own routefinding on logging roads. It’s a quiet, little known and infrequently visited spot, less than an hour’s drive from Seattle.

The Rhyacian Period ( /raɪˈeɪsi.ən/; Ancient Greek: ῥύαξ, romanized: rhýax, meaning “stream of lava”) is the second geologic period in the Paleoproterozoic Era and lasted from 2300 Mya to 2050 Mya (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.
