Road closure killed the original plan of picking up Iron and then running the ridge south with a car shuttle. The Mount Gleason Road was closed at the Angeles Forest Highway, so 21 sturdy folks slogged the excruciatingly gently graded trail from Big Tujunga to Fox. Eight hours, 15 miles roundtrip.
Thorny ceanothus tends to crowd the trail at points. Bring clippers and long pants.
