This was three short trips in one, in the mountains north of Detroit Lake. First, I hiked to the top of Dome Rock via the Tumble Ridge Trail. Then I drove over to Knutson Saddle and hiked/scrambled up Sardine Mountain, which was a ton of fun. Finally, I went north on Forest Road 2223 as far as my little car could handle (which turned out to be about 200 yards short of end of the road) and checked out Phantom Natural Bridge.
