48451 Pichincha           Discovered 1991 Aug. 2 by E. W. Elst at the European Southern Observatory.
Pichincha is an active stratovolcano in Ecuador, very close to the capital Quito. In October 1999, one of the peaks, on the western side of the mountain, erupted and covered the city with several inches of ash. The last major eruptions were in 1553 and in 1660.
