Weather: Partly sunny. Temps in the mid 40s with gusty winds from the west out of the canyon. A light breeze in the canyon..
Note: This was a cross-country hike. Access is mostly through game trails on public lands with routes crossing some steep, talus slopes. Also, the poison oak is pretty thick along this route! Private property blocks access both from US Highway 30 and upstream along Rowena Dell. The easiest access is to park along Dell Road and then hike to the west rim of Rowena canyon and find a route down to the creek.
