Museum on UNM campus
This is a very nice museum on the UNM campus. It's also free (donation box). It has a full-size diorama of a cliff dwelling, models of various extinct people, corn the kids can smash on grinding stones, and about 100 other things. It's a nice walk across the campus to get there, and I think there is some parking about 100 feet to the west. It's well worth 1 or 2 hours.
