Riding up the hill and passing the road to the Sisson Mine.
That's the road on the left of me with the 2 trees across it.
What's left of the Big Boulder Mine. Singletrack trail starts past here.
Keep to the right at the split. There is quartz rock strewn on the ground.
You can see a trail sign on the right that sez, "Downieville Downhill".
After the right there is a view of the Sierra Buttes.
We started this mountainbike ride on the left shoulder of the mountain.
