Ascent Trip ReportClimb and circumnavigation of (counter-clockwise) Mt. Thielsen from Thielsen Camp
We set a very leisurely pace on the ascent (via path), then descended directly down the scree fields to SSW. It went from clear to thunderheads in approximately 1 hour from noon to 1pm during our descent from the summit and ascent of South Thielsen.
The climb is very easy low-5th class. We used a small diameter rope as a hand-line for added protection, strung from an old yellow "Obsidians 12ft" piece of webbing that appears to have been placed in 2011. It appeared solid, though I wouldn't rely upon it as fall or body-weight (full rappel) protection with all of the lightning activity that the peak experiences. The 'rope' was slightly helpfull for the descent, though we would have felt comfortable descending without it. A 100' length would have been just sufficient to reach from the webbing to the 'landing' below the summit block.
Though this may not hold true in each case, it was interesting to note that the thunderheads that occurred on July29 and July30 first built north of Holly's Ridge and east of Sawtooth Ridge, rather than directly over Thielsen's summit. On both days they eventually extended above the main summit, but only after a time. Regardless, the main summit is a terrible place to be with any measure of lightning activity (or even threat) in the vicinity.
The summit register was not in any of the 'obvious' places, and there was a swarm of insect/wasp bugs (harmless) on the highest summit rocks that discouraged a prolonged attempt to find it.
2 others (from CA) joined us on the summit - Jaime & Laura(?)
