So in love with this.

Thanks!

Hi Ingrid. If I swap in my location `.center([-122.84032427147605, 38.0610864116276])` then I end up with a bunch of errors on the notebook stemming from the `hillshade` cell. Possibly because I live near the sea, and so some of the tiles will lack the requisite data. Could you recommend how I might fix that so I could fork this and play around with it for my area?

Ah, yeah, there are some tiles without any hillshade data so the map function in the hillshade cell is returning an undefined. I added a filter in there to only return tiles with hillshade data and republished it with your lat/lon, hope that helps!

That's so kind of you, thank you. I just came to say I'd figured it out, but my solution was much clunkier than yours, so I'm happy to see how it should have been done. I'll fork this now, and then feel free to swap back in your original lat/lon because I think that map looked much prettier than mine.
