We hike a loop route through the hills above Peterson Creek every year, going along the rim, avoiding fencelines, going quietly, enjoying spring. We started at the Whiteshield Trailhead and first did the Grasslands Loop for the view up the valley.
We crossed the creek on a log to go over to the East Rim trails.
From the hilltops above we had fine views into the two valleys below.
After crossing Peterson Creek for the second time, we started the steep climb up the western side of the canyon, back to the viewpoints on the way back. The confluence of the two rivers was full during freshet.
Peterson Creek Trails are well-used by hikers, dog-walkers, and mountain bikers. Various routes can be combined and if the East Rim Trails are included, there will be a steep climb to return to the start, but its all worth the effort.
