Ryan Cooper and I started at the upper bristlecone trailhead with the intent of hiking to bonanza trailhead and back with the hope of gaining 10,000' of cumulative ascent in 30 miles. There are some confusing trail junctions in the upper and lower bristlecone trails, and our route did not quite equal 30 miles nor did it come anywhere near 10 thousand. We were unsupported and hoped to filter water at wood spring, it was dry. The week before we had found an elk guzzler near the parking lot of bonanza trailhead and marked its location on our map.

Here there's a link of the route starting from the cable car (Funivia Ciampac) of Alba di Canazei: https://www.planetmountain.com/itinerari/files/Vie_ferrate/pdf/045.pdf / https://www.vieferrate.it/pag-relazioni/relazioni-regione-veneto/84-marmolada/139-punta-penia.html (look at the second way to access the route, from Val Contrin and not from Passo Fedaia). The rout

Start:  PCT Trialhead on "Old Donner Summit Road".   Just off of Historic Highway 40 at Donner Summit.   39.31471N.  -120.32727W

End:  "High Camp", Palisades Tahoe.  The upper gondola station.    39.195235N, -120.261267W

This point-to-point route offers spectacular views along the crest of the Sierras.  Easy access to the start and end points.  After ending the run, take a free ride down the gondola to Palisades Tahoe Olympic Village.       Most of the route follows south along the well marked PCT.
