Description of welded tuff is wrong. The fragments within a welded tuff are not primarily "ripped up from mountain''. The larger fragments are flattened pumice fragments which are part of the pyroclastic flow and the matrix is generally made of glass shards (fragmented pumice) - which are also flattened in a welded tuff.
A bit of preparation would have made this a fascinating video. Extra slides of no importance, reading from text, scratching head frequently, making fundamental errors, and blaming technology does not do justice to such a fascinating topic. Go and watch Shawn Willsey, and appreciate quality geology that inspires.
Really enjoyed this, thankyou.
Thank you ❤
Thanks very much 😊
Fabulous presentation, thank you!
Thank you for putting this on you tube

Min: 26 was were it was sheltered (a crag just before a step drop) from the wind when sleeping and my camp the other night! Good content.
Glad you're enjoying - and the memories too 🙂

That’s another great suggestion
