Pika, ColoradoIt’s been a while since I’ve been to the Rocky Mountain tundra for marmots and pikas. This one is from way back in 2007. The pikas were sunning themselves with the last rays before nightfall in Rocky Mountain National Park in Colorado. Nikon D200 with Nikkor 600mm manual focus f/5.6 lens, ISO 400, f/8 at 1/250th of a second.
