Cool! I wasn't familiar with this site.

I primarily use this one: https://macrostrat.org/map/#x=16&y=23&z=2

I'm comparing the two.... I think the USGS one you link to is a bit more consistent across the country. But Macrostrat has better detail in certain regions. Around LA, I upon initial comparison I think I give Macrostrat the edge with more formations mapped, but USGS does give Mt Lukens and the Verdugos two formations instead of just one!!

Good additional resource to cross reference! Thanks for the link!
