I backpacked the American Discovery Trail segment from Auburn to Sacramento this week. This is my second time on this segment (ADT: Auburn to Sacramento 2012-05), and the reasons I went again were to see the American River North Fork while the draw-down of Folsom Reservoir exposed more of it, and to create a GPS track of the trip.
I took the Amtrak train to Auburn, then walked to the trailhead at Auburn Staging Area, and then down into the canyon to sleep. I took a few wrong turns in the dark, but quickly realized and corrected (and I have corrected the GPS track). Not far into the canyon, I noticed the sound of the river much stronger than I remembered it. The night was cloudy, then cleared to brilliant stars, and at dawn there was a light drizzle. I headed down the Cardiac Bypass Trail, which is better signed that it was two years ago. These signs are unusually clear for a state parks-managed area, so I presume they were designed, paid for and installed by a volunteer organization.
