In February 2010 I drove up the hill behind my house once again and recorded more ice breaking. Keep in mind this "back hill" peak is actually 4000 feet above Sandpoint, Idaho. This time I found a very large water containment pond that had frozen solid when it was extremely cold back in January. The standing water under the ice had drained away and the top 8 inches or so of ice had collapsed in on itself. It was hollow under the ice and around the edges the ice was still hanging on to the rock like a ledge. This made for some rare ice recording and I was ready! I was able to break away chunks of ice at least 8 inches thick and throw them around. I got some really good sounds of heavy pieces of ice sliding, scraping, dropping and hitting.
I used a Sound Devices 702 recorder with a Sanken CSS-5 microphone and a Sony PCM-D1 both at 24bit 96kHz.
