Thanks - YES, the Guernsey Rutts are amazing. Yellowstone definitely/ I travel with a geologist (!) so rocks are must-see. Have not been to Estes Park yet. Thanks.
Have you traveled Yellowstone before?
Last week, the Old Faithful area was very, very crowded. We ended up skipping it. Too many people without Covid, but really didn’t want to deal with it during Covid. Other areas of the park were fine.
