Fodor's Expert Review Quitsato
If Intiñan approximates high-school science experiments, Quitsato, where the equator crosses the Pan-American Highway on the way to Otavalo, offers the subject's most academic treatment of the three sites, with ongoing research into the astronomy, history, and archaeology of equatorial observation. Quitsato's highlight is the enormous, 54-meter (177-foot) walk-on sundial, which, of course, casts no shadow at noon. The Solar Culture Museum here has an informative bilingual talk about peoples' use of the sun in measurements during the pre-Columbian epoch. The site is a standard stop on many of the day tours out of Quito to Otavalo.
