Spring and fall. Opalized wood from Cottonwood Spring near McDermitt.
Colors are predominately white and green.
Take this road about 0.2 mile to the wide parking and camping area at the bottom of the hill. Park here and hunt on the hills in all directions. We found some very nice pieces on the uphill slope on the east side of the road and on the downhill slope on the west side. Don't be afraid to do a little digging. .
