Hidden Forest Trail, Fifteenmile Creek Railroad Grade — Wednesday, Apr. 17, 2024

Issaquah Alps > Tiger Mountain

The Hidden Forest, 15 Mile RR grade, and the 2 miles of the TMT that runs between them have very few visitors. They are in good shape with only a single blowdown (on the TMT just north of the 15 mile junction, there's a bootpath workaround). They are south-facing with lots of deciduous trees; they are very sunny in the spring. There were lots of visual delights: Siberian springbeauties (photo 1), fading salmonberry (photo 2), just bloomed red elderberry (photo 3), evergreen violets (photo 4), and more (see slideshow).


Newly blooming flowers: Hooker’s fairy bells, woodland strawberry, and purple deadnettle.
