1. If you stated your post correctly. YOU NEVER LEAVE THE DUMP VALVES OPEN WHEN CAMPING. ESPECIALLY THE BLACK TANK. COLD or Hot weather

In warm weather or long term, I agree with your assessment.
For a quick weekend in really cold weather, I'll disagree (30F is not really cold weather).
One weekend isn't going to create the pyramid and assuming you otherwise let the tank fill and sit a bit between dumps, anything that does start with get taken care of by sitting in the half full tank.
The trade off in really cold weather (assuming you don't have heated tanks) is that things freeze and bust.
As far as the OP's issue, it's possible that things got pressurized if the vent tube slipped down towards the bottom of the tank. When the airspace warmed up during the day, the pressure had no where to go except to push water up vent tube. It overflows and runs back down the outside of the tube before dripping down and forming icicles. The waste water could also find it's way into the walls where a lovely aroma can develop.
