Sycamore Canyon Professional Review and Guide

"A narrow crease incised into the westernmost Puente Hills, Sycamore Canyon harbors some fine riparian habitat overlooked by rather dramatic, eroded cliffs. There are several large and twisted specimens of California sycamore trees to admire, as well as willows, cottonwoods, and toyons—the latter bearing clusters of bright, red berries in late fall and winter."
