Coolant Leak

What is your question?

I have a coolant leak in my 97' Jimmy. It's more than just a leak, it's a flow. I have located the leak within a small area, but unsure exactly where it is coming from. I have pics of it if needed and the area is about the size of a softball. It seems to be coming from or near these 3 metal hoses that run together. The metal hoses are located on the driver side behind the motor a bit. Does anyone have an idea of what exactly could be leaking? INCIDENT: How it happened was one night I was driving and the temperature gauge started shooting high, steam/smoke started coming from under the hood. Did some inspecting, obviously coolant is all over the place, but also ONLY a half quart of oil is in the motor?! I had no oil spots in the driveway and the oil gauge didn't warn me. The oil was due to be changed, but not overdue.
