INTRO

Unnamed Road (Off Mosquito Ridge Road) to power station at bottom of ravine - This descent from Mosquito Ridge Road down an unnamed road to a somewhat eerie and desolate hydroelectric dam is quite the challenge, particularly after climbing Corkscrew and Mosquito Ridge. Mosquito Ridge’s 18 mile stretch of road from the start of the Mosquito Ridge climb (at the bridge over the North Fork of the Middle Fork of the American River - really, that’s how it’s referred to on the maps!) is home to some incredibly difficult and remote Northern Sierra Climbs - Unnamed Road being one of them.

Interesting climb within interesting and isolated territory. Watch the descent which you have to do in order to climb back out. Once down, check out the river and dam near climb start. Once heading up, it contains very solid grade through its middle core through nice switchbacks, easing towards the top. Definitely worth the effort to get there.

CLIMB SUMMARY

INTERBAY ROAD (OFF MOSQUITO RIDGE ROAD)

This descent from Mosquito Ridge Road down interbay Road to a somewhat eerie and desolate hydroelectric dam is quite the challenge, particularly after climbing Corkscrew and Mosquito Ridge.  Mosquito Ridge’s 18 mile stretch of road from the start of the Mosquito Ridge climb (at the bridge over the North Fork of the Middle Fork of the American River  - really, that’s how it’s referred to on the maps!) is home to some incredibly difficult and remote Northern Sierra Climbs - Interbay Road being one of them.  We have not been able to identify the name of the road or the hydroelectric dam at the bottom, but the road is on the right side of the Mosquito Ridge ascent precisely 10.8 miles from its beginning at the bridge at longitude/altitude 39.05182, -120.616433.  We charted the climb here:  RideWithGPS Map.

The beginning of this climb is just up the hill from the dam at 39.02937, -120.60419 latitude/longitude.  There was no traffic on this one - it is remote, desolate and a bit creepy!  The roadway is paved and was in pretty good shape which was a bit surprising given it’s ghost-town feel . . . hey, was that a tumbleweed that rolled across the road in front of me?

This monster climb, done in conjunction with Mosquito Ridge and Corkscrew, offers a formidable climbing challenge at 58 miles and 9,925’ of climbing:  Map.

Our friend from Campbell, CA, Dan Razum writes on 7-28-19:

“You mention a climb on "Unnamed road", some 10 miles up Mosquito Ridge.  I'm pretty sure the name of the road is Interbay Road, the dam is Interbay Dam and the power station is Midfork Powerhouse.  It may not be listed on Google Maps, but that is what the signs on site indicate.

Interbay was not spooky at all.  Very sunny, which I think alleviates any spookiness and I encountered 3 vehicles (1 from the power company and 2 private cars). So it didn't seem uninhabited.  By the way, I'm guessing the sign saying "Interbay Road" probably wasn't there when you went.  And the plaque near the dam is easy to miss, I almost didn't see it. So don't feel bad about missing the names.”
