The ride begins at the Four Corners intersection, 3 miles above Yreka on the Humbug Road. The first six miles out past Mahogany Point are a steay uphill pull, gaining approximately 1,700 feet to the crest at Gunsight Peak. Gunsight marks the beginning of 10 miles and 3,300 vertical feet of downhill bliss. you head down the main road for about a miles to the intersection of the Sucker Creek Road (45N53), where you turn onto a 7 mile run of great doubletrack that's blocked to 4WD vehicles. There are patches of losse rock and steep dropoffs on this road. At Humbug Creek the route moves onto a graded road for a couple miles, following along beside the Creek. You'll cross a bridge. A short way beyond it, hand a sharp right onto road 45N30. It's payback time for all that fun, with a long, grind-it-out, granny ring pull for 1,600 vertical feet back up to Four Corners. The thrill of the downhill lingers, but you'll be glad to get back to the top. Two full waterbottles is barely enough.

From anywhere in Yreka, head uphill on Miner or North streets to Humbug Road, take a right, and follow the dirt road for the 3 miles on up to the Four Corners saddle.

Along the way are fine views of Yreka, the Shasta Valley, Mt. Shasta, the Humbug Creek basin, and the Scott Valley. This is a long, dry ride with a lot of Climbing. Really strong riders might enjoy beginning this ride in Yreka, using the 1,800 foot climb to Four Corners for a warmup.
