"I'd go to the local University that teaches Fortran and ask around."

Aye, there's the rub.

SIUE (Southern Illinois University at Edwardsville) still had a COBOL curriculum a decade ago, and they might still.  They were fairly forthright in training people to go work at a lot of the stodgier St. Louis enterprises that still had a large COBOL footprint (AB, Enterprise Rent-A-Car, Caterpillar, et al).  By 2010, though, Express Scripts was trying hard to move away from its ANCHOR (COBOL) system and whatever-it-was-they-had running on VMS, and it sure felt like in the early 2010s STL was mostly Java EE.

I would think that FORTRAN is likelier to be passed around as folk wisdom and ancient PIs (uh, Primary Investigators, not the detective kind) thrusting a dog-eared FORTRAN IV manual at their new grad students and snarling "RTFM!" than as actual college courses.

That said, if you want to learn FORTRAN and don't mind working from modern FORTRAN back, I really was impressed by https://lfortran.org/ , and the ability to run it in a JupyterLab playground environment is fantastic for quick-turnaround experimentation.  Plus

My training was 35 years ago, I have no idea where to go look for this
stuff now.  I googled and didn't find much.  I'd go to the local
University that teaches Fortran and ask around.
