Hydraulic mining shaped the reddish cliffs along this highway corridor. From the 1850's until 1885 jets of water were used to break down gold-laden gravel and to wash the material through gold separating devises called sluices. This practice was halted by Federal injunction. During those 30 years it is estimated that hydraulic mining in the state yielded over $100 million in gold.
