Great collection. Love the interaction on #2, the action on #4 (looks like some critter is about to get it), good incorporation of scenery (I'm almost not sure which is more the subject, critter or the mountains) #5. Number your pics next time to make is easier for comments.
Thank you for your kind words. I used a EOS 1DMarkIII with a 400MM 2.8L IS and a 1.8X converter for most of the trip. I had to hire a guide to take me in during winter season. It was my second trip and I used the same man as the guide. There much fewer people in the park during winter and you must travel by Snowmobile or other vehicle with tractor type wheels. Although it is Illegal to take the Snowmobile of trail, we parked and hiked in deep snow to get certain shots. We would only move one at a time allowing each other to set up for a shot in case the animal would flee. We took risks with to get so close with no escape routes. I have some great video of the howling at about 6pm every night.
