'85 and there's a decent amount of coolant leaked this morning from my car. I took a pic of where I believe it's coming from. Freeze plug?

 

best way i have found to trace a coolant leak is from the top down start from all the hoses. and then check radiator squeeze the hose to see if you can get it to leak with out running if you cant get it by then try having the engine run for a bit to see if you can find it

 

as suggested above, try to trace the leak. i would start by checking around the intake manifold.

 

Look at the top of the engine, do you see any coolant puddling around the Intake Manifold (like Diabolical said)?

If you don't see any on top try feeling under it. Intake manifold gasket is a common leak.

(Score reminder: Ghooble 1 Diabolical 0)

 

bastard ....

 

Possibly the beehive water to oil cooler too.....little O-rings there that get hard, brittle and leak.
