Paul, where do you enter from? What kind of elevation do you get to? I've only entered Sequoia/Kings Canyon from the west a couple of times (for a Natural History class in 2003), and those were just day hikes in Mineral King and up Bubbs Creek. I'm generally heading for the crest (I'm happiest at and above timberline), so east side entries are shorter if steeper. I'm thinking I'd better get my trips in as early as possible this year, as I expect the fire season to be even worse than 2020. I was planning to do Shasta again, until I saw on the webcam that there was less snow high on the mountain on April 27th than there was in a screenshot I took last July 15th
Here's what the south and west side looks like now, essentially bare: https://sc.snowcrest.net/index.php/snowcam
I'll happily pass on toiling up 6,000 vertical feet of loose scree, dodging rockfall as I go.
