Ascent Trip Report

This 10-mile loop hike began at the Rimcrest Drive entrance to Chino Hills State Park and followed the wide South Ridge Trail (a road, really) east through almost 3 miles of 8-foot high mustard plants in beautiful bloom. The ascent to San Juan Hill summit was a clearly-visible use trail. There was no register at the summit marker, although a hiker enjoying the views from there said he had seen a register can 100 feet to the east several years ago. I decided not to search for an overgrown register can since that effort would have involved foxtails in my socks. As I descended San Juan Hill, I saw that other GPS tracks--for the walk across the canyon towards Gilman Peak--lead through thick mustard plants that had grown well above my head. The trail those tracks followed had been a mowed swath through prairie, but it was so high that I couldn't see landmarks on any side. I returned approximately a quarter of a mile on the South Ridge Trail and found a connector path leading north to Telegraph Canyon Road. At that point, tracks leading up the ridge east of Gilman Peak also were too overgrown for me to locate a path, so I continued west on Telegraph Canyon Road. A couple bicyclists complained about getting slapped in the face with mustard plants. On the USGS map, there are two trails leading north from Telegraph Canyon Road to Gilman Peak. I searched at length for the eastern one and couldn't find it. The western one had a signpost. While this trail is heavily overgrown with mustard and thistle, the underlying use trail can be followed fairly easily. This part of the hike requires long pants and sleeves for protection from the vicious thistles. Upon returning to Telegraph Canyon Road, I walked west and watched for the Easy Street connector back to Rimcrest Drive. This GPS track is an alternative to tracks that were saved earlier in the spring when the vegetation was not so lush.
