Chimborazo
The summit of Mount Everest is higher above sea level, but the summit of Chimborazo is widely reported to be the farthest point on the surface from Earth's center, with Huascarán a very close second. The summit of the Chimborazo is the fixed point on Earth that has the utmost distance from the center – because of the oblate spheroid shape of the planet Earth, which is "thicker" around the Equator than measured around the poles. Chimborazo is one degree south of the Equator and the Earth's diameter at the Equator is greater than at the latitude of Everest ( above sea level), nearly 27.6° north, with sea level also elevated. Despite being lower in elevation above sea level, it is from the Earth's center, farther than the summit of Everest ( from the Earth's center). However, by height above sea level, Chimborazo is not the highest peak of the Andes.
Cordillera Huayhuash
The Huayhuash range is 30 km long north to south and includes seven peaks over 6000 m including Yerupajá which, at , is the second highest peak in Peru. Another notable peak, Siula (6,344 m) was made famous by mountaineer Joe Simpson in his book "Touching the Void". Unlike neighboring Cordillera Blanca, Huayhuash doesn't possess broad valleys and mountain passes are higher. There are many lesser peaks surrounding those covered by ice, and several passes exceeding 5,000 m. It is necessary to travel a considerable distance from the central range to find ground lower than 3,000 m, even on valley floors, and the range is often taken to include this much larger area. The vegetated areas of the range are part of the Central Andean wet puna ecoregion
The area is barely populated at all, with what hamlets there are being very small and generally only found below 4000 m (the snowline is found at approximately 4,800 m). The nearest villages are Chiquián (3,400 m) and Cajatambo (3,375 m). Some mining takes place in the area, so to the north of the mountains there is an unsurfaced road leading up to as high as 4750 m. In 2002 the Peruvian Ministry of Agriculture declared the Huayhuash mountain range a "reserved zone" and prohibited certain economic activities, including any future mining.
