Although well-graded, the "Yellow Grade" road up to Cerro Gordo ghost town is very steep. Shifting into four-low is a smart move because the gear reduction makes the grade easier on the engine and transmission. On the descent, low range is easier on the brakes. The "Yellow Grade" road (AKA Cerro Gordo Road) was once the only way into and out of Cerro Gordo. Millions of dollars' worth of silver and lead bullion were trekked down this winding route. The road is maintained by Inyo County and is open to the public. There's private land on both sides of the road.
