Negit and Paoha islands and dark, flat-topped Black Point on the lake's north shore. With its eastern entrance at Tioga Pass just 45 minutes from Mammoth, Yosemite is a favorite day trip for Mammoth vacationers. Relax alongside sparkling Tenaya Lake, walk along Tuolumne Meadows, watch rock climbers and take in the inspiring Yosemite scenery. It's easy to see how it was here, in Yosemite, that John Muir formulated the theory that glaciers carved the Sierra range. A self-guided auto tour brochure provides additional information on regional geology, and is available at the Mammoth Visitor Center on Hwy.
Local shops carry scores of guidebooks to the area, too.
