Below is the note from a Trail Descriptions - The Pacific Crest that intrigued me enough to write the first chapter of Wataarka Sunrise. It's a short description rife with possibilities:
"John Muir Trail Section 2: Tuolumne Meadows to Devils Postpile"
Cross two passes, ramble along tear-drop alpine tarns, and camp in spots framed by classic High Sierra vistas on this 28-mile section of the JMT. Start out at the flattest section of the trail, but soon charge toward the higher elevations of the Ansel Adams Wilderness. Finish at Devils Postpile National Monument, where frozen columns of lava pierce the sky around the volcanic shoulders of Mammoth Mountain.
