Cracked Block or Blown Freeze Plugs?

What is your question?

This morning on my way to work in ICY conditions...I slid off of the road into a ditch. I was on a rural road so I just put the truck in "D" and gunned my truck and got myself out of the ditch. After driving about 3-4 more miles, I noticed that my temp gauge was going up and it went all the way to HOT. I pulled in a gas station and let it sit for a few. I went inside and bought 50/50 Antifreeze and as fast as I was pouring it in, it was running out from near the bottom of the motor. It was definitely not a hose or didn't seem to be and definitely not the radiator. The Truck has 220K miles on it so I drive it soft but I wonder if i did something when I gunned it this morning to get out of the ditch. ANY help would be appreciated.
