Where is it leaking coolant?

2001 Suburban Loosing Coolant

Got a message on the DIC "Low Coolant". It has 290k miles. WP replaced around 150k miles. Radiator, hoses and connectors are original. Reservoir level is very low. I saw coolant dripping at the back of the engine oil pan under cover. Probably dripping on the under cover and running down the back.
I'm going to park it for a while until I can find time to investigate as I am going out of town for a few weeks.
Any guesses?

Bel, if it's coming down the back of the engine, I'd be suspicious of a leaking freeze plug.
