Good stuff. Points up the considerable variety of topography in the North Cascades. The central Pasayten looks a lot like large portions of the Colorado Rockies, and is sometimes misidentified as such in photos.
I have watched this video several times. I like the balanced approach to the journey. The video would be boring if it just showed climbing. We see the whole journey from pre-dawn departure to ferry, then mountain bike, then trail, then up the steep track to high camp.
This is seriously impressive for a 1 day adventure. I roughly drew your route on Gaia and am just mind blown haha. So sick! Such a prominent feature in the North Cascades!
