Thank you for building this; over the years the bus animation has gone a bit wonky, but otherwise the page holds up really well. It’s a great library you built.
This is the first time for me where a website hijacked the scroll wheel, and it's actually _really really_ well done. This is amazing. Thanks for posting it.
The key is that it doesn't actually hijack the scroll wheel - the main content (header and text and photos on the left) all scrolls normally, controlled by the browser. The map just monitors the scroll position and element client rects and runs its own non-blocking visualization on the side.
I agree - beautifully implemented, and great content too.
Fyi for those who tap in and see the map in the background instead of to the right of the content, the layout/treatment feels pretty different for desktop vs mobile.

I thought this was so compelling that I ended up walking the trail myself. Incredible experience.
