We did Harney/B.Elk in under 3 hours, but that was summer conditions. Give yourself a full set of hours to slug your way through snow/ice. Good Luck!Saw a pack of 7 deer, and two white long-horned sheep (not sure what they're called) on our way out of the park this afternoon. No bison (yet). Have on video but no still shots. How can one paste videos here (or can't we)?
Planning to try Black Elk Peak tomorrow (or some other trail nearby, along with either Custer and/or Rushmore) or Mon (the other day driving to Devil's Tower, Spearfish, and Deadwood). Son wants to fly his drone near DT on Monday since it's supposed to be sunny.
For Buffalo, they'll only be at Custer.
