This photo was definitely a challenging one to get. It wasn’t possible to crawl down the opening that led to this mouth full of teeth, so I attached my camera to my monopod, turned on the time-lapse feature, flipped the articulating screen so that I could try and compose the photo from a distance, and then lowered the camera (upside down) into the small ice cave. All the while I was saying over and over again, “Don’t let go of the monopod. Don’t let go of the monopod.”
