A few years ago I did what was a traditional end-of-season backpack trip out of Tuolumne Meadows on the last weekend during which the NPS permits overnight parking on Tioga Pass road – this is typically on or just before October 15. It was a beautiful weekend with – as I always hope for in October – pleasant, sunny conditions and beautiful light.
The following weekend a backpacking buddy who had been unable to make that trip tried his own end-of-seasons visit, hoping to wander up into the Twenty Lakes Basin area just east of Tioga Pass. He arrived late and rolled out his bivy sack at the small campground by the lake right below Tioga Pass… and woke up the next morning with more than a half foot of snow on top of him and more on the way. He scrambled out of his bag, got into his car, and managed to get out just before the road was blocked. He liked to say that he was there for the switch from fall to winter… literally.
It sounds like something similar may happen over the next 24 hours. From all reports, one of the biggest October storms that we’ve seen in California in decades may be sweeping through tonight and tomorrow, bringing heavy winds, a lot of rain, and the potential for some significant snow at the higher elevations.
The folks at the Dweeb Report (interesting source of Sierra weather info) include an ominous sentence in their most recent update: “WINDS WITH THIS SYSTEM OVER THE CREST COULD REACH BETWEEN 120MPH AND 140MPH OVER THE CENTRAL SIERRA.”
Of course, you knew this was leading to a comment on aspens, right? Given the rather strange conditions for aspen color this fall, somehow it doesn’t seem at all surprising that the storm might bring down a good portion of the remaining leaves!
