"The western reaches of the Nobles Emigrant Trail are a mixed bag. The segment described here, from Lost Creek to Lassen Park Road, was the site of a controlled burn in 1999, and is littered with firefighting equipment and the detritus of construction and maintenance. While this may be interesting to some hikers, it is a less than pristine experience. As you begin to climb toward Nobles Pass, however, the path takes on a mantle of both natural beauty and historical richness. A marker at Sunflower Flat, just below the pass, commemorates the pioneers that used this trail. Once over the summit, you will pass through the Chaos Jumbles, remnants of a massive avalanche off the Chaos Crags that now fosters an open woodland of Jeffrey pines. A few artifacts and a little imagination lend poignancy to the remains of Summertown, at trail’s end near the western boundary of the park."
