Power steering fluid boil?

[Eighties Meta]

The one odd thing at the last track day was at the end of my final session when I parked, I saw steam(smoke) coming up from what I thought the passenger wheel and over the hood. after opening the hood there appeared to be some liquid splashes (a very small amount) on the passenger front left side just under the Power steering fluid reservoir, least, I think it's the power steering fluid reservoir. now that I think about it, whatever that is. The top was wet so I dried that off and am just assuming that's what it was. No codes showed on the car and I drove home from NJ (2.5 hours) no problem and no problems today.

I just don't recall anyone ever mentioning Power steering fluid boiling or overheating? wtf?

this was at like the almost 6pm at the track so everybody was gone I was literally one of the last people to leave so fortunately my no knowledge about car self wasn't stranded.
