We planned for about three days in the Colorado portion of the four corners exploration, specifically to visit Mesa Verde. We knew conditions might be a bit dicey given the high elevation, and as the date got closer we knew it might be best to have a plan be. Still plenty of snow up there and very cold days, so we camped at and focused on Canyons of the Ancients.
The visitor center is outstanding, especially for a national monument. Good film and very good artifact displays. It also goes into depth on the methods used to dig and conduct the research in the area.
Lowry Pueblo was a nice and easy visit with a nice selection of original and restored Puebloan ruins.
One big highlight was our camping spot by a big cliff overlooking canyons (ruins down there too!) and Sleeping Ute mountain.
