Much to my surprise I think you are correct.
QGIS can open a TIF file (and a zipped TIF file),
but I can't get a GeoPDF to open in QGIS. If I

Good evening MacKinnon's,
although being rather familiar with GIS, I don't Know yet GeoPDF. Tried to
load your USGS download file in QGIS 3.12.0 on Win 10. Had also trouble,
although I didn't got an error message. But the CPU of my system reached

Hello, low skill user here on QGIS 3.2.3 on Microsoft 10. I have been
