Looks like maybe a tropical orb spider - but i photographed this in the woods in Johnstown, Pennsylvania, USA

Could it be a particularly red-toned Araneus marmoreus, the marbled orbweaver? It’s definitely an orbweaver, though I don’t think Eriophora species are found as far north as Pennsylvania.

Looks like a marbled orb weaver to me.

Hi, this is a Shamrock Orbweaver (Araneus trifolium). Looking a bit shriveled/dehydrated she has likely already laid her eggs.
