Look here for section by section trail journals from my 2021  southbound attempt on the Pacific Crest Trail. I went up to the Canadian border, then south all the way to the Lionshead Fire Closure south of the Timberline Lodge. Then jumped down to Walker Pass to avoid a bunch of fires and headed northbound until I got snowed out of the Sierra just south of Bishop Pass. From there, I went back to Walker Pass and headed southbound until I was too lonely and tired to continue just south of Agua Dulce at the KOA.
