Here’s a photo of my audio gear in the corner of an office that was very kindly provided for our use. It’s followed by a shot showing the omni mic I rigged onto the strap of my recording bag. I was hoping to have a true Mid-Side setup this time around but couldn’t get the figure-eight mic I needed. This setup isn’t ideal but it gives me a different perspective on everything I record. (I’ve got two inputs on my recorder so might as well use them both.) The brown fuzzy is a DIY wind screen made from fake fur.

• Low temp: -2 F
• Average Wind Speed: 46.7 mph gusting to 72 mph

A foggy day with visibility down to 1/16th of a mile. The observatory reported zero hours of sunshine for the day. Perfect conditions for rime ice. We could hardly step outside without it accumulating on our clothes and, of course, our gear.

My recording bag covered in rime ice. My headphones were unscathed since I wore them under my balaclava (and hat (and parka hood)).

I brought out my contact mics to record the sound of rime accumulating on them. The best spot I found was attaching them to the windward side of a wooden sign post. Here’s an excerpt:

Listening to the entire recording one can clearly hear the frequency of the resonant ping sounds increase as more ice accumulates. I suspect the ice accumulation reduces the surface area of the contact mic or otherwise stiffens the transducer–in a manner similar to a drummer increasing the pressure on a drum head and thus causing the pitch to rise.

Here’s a recording of an ice-covered chain squeaking in the wind. The squeak is less metallic than I expected, sounding more like rubbing ice cubes together.

Here’s a photo of the chain (taken on another, much sunnier day). Yes, this chain appears to be preventing the building from blowing off the mountain. The story I heard is that the chains were an important part of the original building. When they rebuilt the structure, chains were included as an historical and decorative element. There were times when I could have used a chain or two to prevent me from blowing away.

Here's all of my audio gear packed up and ready to go.

January 9: We all gathered at Jackie’s house, threw our gear in the van and drove to New Hampshire. Jacqueline Goss was the leader of the crew: video artist, writer, director, producer. Jesse Cain: cinematographer. Dani Leventhal: talent. (She hates that word, but after spending the better part of a week together I think it fits just fine.) We spent the first night enjoying the comforts of the Appalachian Mountain Club Joe Dodge Lodge. Jesse unpacked and assembled the camera so we could begin shooting first thing in the morning.

January 10: First thing in the morning we met our ride up the mountain (snow tractor!) at the Auto Road and took a minute to shoot a few establishing shots.

Mt. Washington (the summit is obscured here--it's just behind the peak on the right)

On the way to the summit we stopped just above the treeline to shoot a few more scenes. I loved seeing the stunted krumholtz trees that are just visible in the lower left corner of this photo.

Late morning, we arrived at the summit and quickly unloaded our equipment. Visibility was good, and since we didn’t know whether we’d get clear skies again Jackie and Jesse and Dani peeled off to shoot some scenes that didn’t require sync sound while I took a look around the observatory and organized our gear.

Summit Weather:

• High temp: 1 F
• Low temp: -5 F
• Average Wind Speed: 45 mph gusting to 62 mph

Here’s an excerpt from the first day of recording; a scene where Dani knocks the rime ice off a sign. These sounds are indicative of winter weather on the mountain: wind envelopes everything, so even rather violent actions produce only faint tinkles of ice.

Late Afternoon Cogs Heads Down, Photo by Jeff Glover

I’m headed to the top of Mt. Washington in about a month. I’ll be recording audio for an experimental documentary project led by Jacqueline Goss. At Jackie’s request I’ve been reading material on the history and operation of the Mt. Washington Observatory. I’m already having fun geeking out about cloud cover and wind speed and fog and rime.

Still trying to figure out how to actually record usable sound in 50mph wind… I’m currently building a handful of DIY contact mics/hydrophones in anticipation of recording ice accumulation and the straining of various summit structures in full-on gales. I’m also building a few electret omni mics so I can have something to take outside with impunity in the worst conditions. I’ll try to post some photos of my homebrew audio projects. Also look for future reports and audio samples from the mountain top.
