Yosemite on my mind..

I am a member of a loosely knit group of wanderers that are planning a 4 to 5 day backpack this June from Tuolumne Meadows, along the Grand Canyon of the Toulumne River into the Pate Valley and climbing back out via White Wolf Camp Ground / Tioga Road

From Our Yosemite National Park's website:
"Often a place where solitude is eminent, wilderness stretches seemingly endless before you, and the Tuolumne River begins its journey; Tuolumne Meadows lies 8,600 feet above sea level, near the eastern entrance to Yosemite National Park at Tioga Pass. The Tuolumne River flows through the meadows of the region, supplied by water from both the Lyell and Dana forks which stem from two of the three glaciers within the park. Known to have many moods, the river tumbles downhill in a number of cascades such as Waterwheel Falls, cuts a mile-deep through the Grand Canyon of the Tuolumne River, and slows to a crawl as it reaches O'Shaughnessy Dam, where it then continues its' journey meandering through the rolling foothills of the Sierra Nevada"

Reportedly (I can find only small snippets of information here and there) there are pictographs and ruins scattered for 100 to 200 yards along a cliff that I just have to see.

From Mildred Brooke Hoover's book Historic spots in California (revised 2002) pg. 549:
"Colored with red ochre, they are painted on the face of a high cliff on Piute Creek a little way from its junction with Tuolumne River. Near the middle of the precipice there is a small cave."
John W. Bingaman wrote in his book Guardians of the Yosemite (1961), Chapter V:
"On a Patrol with Ranger Walquist to Pate Valley, we spent some time investigating the Indian Pictographs on the Canyon wall, one-fourth mile north of the Trail Camp. Ranger Walquist and I searched over the Canyon Cliff looking for other places where the markings and pictures have been reported for many years. We found one location near the House Pits averaging twelve feet in diameter. It appeared that the Indians occupied these places the year around. The age of the Pictographs could be anywhere from two hundred to one thousand years or even more. Pictographs are found in some fifty places throughout California. Nothing can be told of the significance of the characters contained in the markings. In no case do the present Indians know their origin or meaning. The Indians of this region do not make representations of natural objects as did the Indians of the Plains. The characters may be connected with some important enumeration of calendar keeping. These Pictographs were first discovered and reported by Mr. McKibben and E. W. Hamden, which they discovered while on an outing of the Sierra Club in 1907."
