The Georgetown Pack Trail was opened in 1850. It left the Carson Route in Carson Valley and ascended Dagget Pass (Kingsbury Grade) into what is now South Lake Tahoe. Following today’s Pioneer Trail it climbed to the summit north of Echo Summit and then followed Highway 50 to Wright’s Road. After climbing Wright’s Hill it crossed Onion Valley (Union Valley) and continued on to Georgetown.
With improvements it became a wagon road taking emigrants to the rich mines at Georgetown.
