This stop is not actually the site of the interesting rocks, but is a good place to park and gather around the tour leader for a lecture. There are markers here for the old Lincoln Highway, the first continuous automobile road across the United States in 1915.
The contact between the Sierra Nevada Batholith and the older rocks it intruded lies slightly west. The older rocks are not granites but metamorphosed and tilted volcanic rocks of Jurassic age. The change in lithology is quite striking.
