Spring Garden Tunnel

The Spring Garden Tunnel at 7,344 ft (2,238 m) in Spring Garden, California is the longest of 34 tunnels on the Feather River Route (cf. Chilcoot Tunnel)[1] and crosses under the drainage divide between the East Branch North Fork Feather River (north portal, 39°53′15″N 120°47′02″W) and the Middle Fork Feather River (south portal, 39°52′07″N 120°46′30″W).

History

The Western Pacific Railroad (now part of the Union Pacific Railroad) built the tracks along the Feather River in 1909 to complete the Feather River Route, a San Francisco Bay Area - Salt Lake City route competing with the Southern Pacific's route over Donner Pass.

While significantly longer, the Feather River Route was preferred by some over the Donner Pass route (elevation about 7,000 ft / 2,134 m) over the Sierra Nevada mountains, because the former's summit under Beckwourth Pass is at a lower elevation (about 5,000 feet / 1,524 m) and most of the route follows a gentler grade along the Feather River.

The tunnel was designated one of Plumas County's "7 Wonders of the Railroad World,"[2] and the north portal is 0.15 miles west on Railroad Street, then 0.35 miles SSE along a fair-condition dirt road from Spring Garden, California.

gollark: Try not to horribly break it or something.
gollark: Perhaps, but the issue is that for some unfathomable reason you use a slice and such instead of `.startswith`, and as it turns out you forgot to update `message.content[:6]` to be the right length.
gollark: Did you know you can do that? Because really, `await` syntax is bad.
gollark: `version = (await (await db.execute("PRAGMA user_version")).fetchone())[0]`
