To find out more about the region's geology, head 18km east of town to this private museum near the village of Tierra Amarilla. Surrounded by working mines, the restored 200-year-old quincho (traditional mudhouse) features eight rooms exhibiting fossils, volcanic rocks, meteorites, minerals and oxidated rare stones. Catch a yellow colectivo from the corner of Chacabuco and Chañarcillo (CH$1000).
