SANTIAGO PEAK DAY 1 NOTICED

I WAS WATCHING A WEBCAM ON SANTIAGO PEAK ON WEBCAMTAXI.COM & SAW THIS. IT WAS MY FIRST TIME SO I DID NOT KNOW THE SURROUNDINGS...I ONLY GOT PART OF IT, BUT SOMETHING WAS HITTING THE CAMERA & I THOUGHT IT WAS RAIN ETC & MAYBE THE OBJECT FLOATING WAS A BOAT...I THOUGHT THERE HAD BEEN A FLOOD. I WAS KIND OF UPSET BUT STILL UNSURE AS TO WHAT WAS TAKING PLACE...LITTLE DID I KNOW...IT WAS VOLCANIC...
