help needed locating LS1 oil leak

I parked my car in my driveway on a slight angle, (with the passenger side being slightly higher than the driver side.) In about 15 minutes it had leaked a puddle of oil about 8 or 9 inches in diameter and was still dripping pretty steady when I looked under it. I got it in the garage where it has been since then and hasn't leaked a drop of oil. It seems to be coming from the front somewhere and dripping down on the driver side of the K-member.

Does anyone know where it could be coming from?

Im sorry I'm not of any help but I had to comment thats a f*cking lot of oil that came out. Geez. Im throwing this out there though maybe the oil pump.
