Muir Woods with a thermal imager

I was back in California for a few days; it was my first time in North America since buying a thermal imager, so I decided to check if it can be helpful in finding those endemic species of the Pacific Northwest that are so difficult to see by other means. I had only two hours in Muir Woods National Monument, but saw a fog shrew, a few deer mice, a couple of dusky-footed woodrats, and, of course, some striped skunks and mule deer. I guess bringing an imager to coastal Oregon or extreme NW California would be a blast.
Ironically, the best sighting of the night was a huge Pacific giant salamander.
