A milestone for the BFRO was acheived this past April during the 2011 BFRO New Mexico expedition, at a remote hotspot in the mountains outside Los Alamos.
Kirk B. (a BFRO investigator from Washington State) brought down his FLIR H-series handheld imager for the trip. It's an expensive military-grade thermal scope that can record short clips of video -- the first type of handheld thermal scope for covert use that can actually record video internally. During the trip he recorded footage of what is very likely a sasquatch watching the camp at night.
Over the past five years several people have spotted and observed sasquatches with non-recording thermal imagers during BFRO expeditions, so the usefulness of thermal imagers, and more importantly, the methodology for identifying sasquatch haunts, and the tricks for luring sasquatches toward a camp, had already been established and repeated in various parts of the country.
Based on prior observations by New Mexico BFRO members, this particular expedition group knew they had a good target area. The bait they used was the base camp itself -- the sounds and smells and activities of the humans.
Even though they were excited to be there, they were also disciplined enough (all ages) to maintain the right atmosphere and body language the whole time, because the right atmosphere and body language could distinguish them from hunters.
They were there to look for something, but they wanted to appear like campers and hikers who brought their own food. They didn't shine spotlights around, and they didn't have guns or dogs with them. Although they made howls at night away from camp, they were otherwise mellow around camp and appeared unconcerned about their dark surroundings. They made themselves approachable.
Faint recordings of vocalizations were obtained a few miles away at "Pam's Spot" on one of the nights, while back at camp, near a very deep dark shrouded ravine that locals call "the Abyss", Kirk B. recorded this tall figure spying on the camp from a distance. It was holding still (it does move slightly at points) and watching from the protection of large obstructions for several minutes. Comparative shots (see discussion forum) the next day showed the height of the figure was a bit over 7 feet. The soil was too hard for tracks (hard and dry with twiggy pine duff litter) but on a rocky shelf-landing nearby there were distinct "butt prints" in the pine duff, according to several participants.
This was not the first time a sasquatch has been recorded with a thermal imager, but it was the first time it happened with a relatively brief effort (3 days), and in the presence of several people who had set out to look for them. In past instances (only 4 instances) the thermal footage was obtained with more complicated systems (imagers connected to recorders) which were not easily portable. Those clunky systems were either unmanned or the camera operator was alone and had spent much time at the location before a bigfoot came close enough.
On many previous BFRO expeditions sasquatches were spotted with covert non-recording thermal imagers (before the recording type was on the market). Those handheld units (L-3 Comm. x200p) were detached from recorders to make them more easy to pass around.
