To set up temperature loggers in the cavities I outfitted them with microchip detectors (to detect any flying squirrels that went into the cavity) and used a "treetop peeper" (camera on an extension pole) to check the cavities for any other small creatures that could be using them. This was to make sure the cavities were empty when I recorded temperatures, so that I was getting the insulating effect of the wood, not any heating effects of animals sitting on my temperature logger.
The microchip detectors had to be attached to large batteries, and the treetop peeper was stored in a large waterproof case, so getting gear in and out of the site was no easy task. Instead of carrying it all, the PhD student had the brilliant idea of taking a snowmobile sled, loading it with the gear and attaching the tree lanyard as a harness. Now getting all the gear in and out was a breeze... unless the snow was wet and sticky, which in that case it was still pretty difficult to pull the sled. BUT once you broke a trail, it was smooth sailing all the way back out.
Not to mention my legs were in excellent shape by the end of the winter!
