Answer 1

It is rectangular, twelve kilometers from north to south, and seven from east to west. It is isolated from the eastern and northern high elevation levels of the (Nilgiris Mountains) by high ceaseless edges including Sispara Peak (2,206 m) at the north end of the park.

Complete answer:
Silent Valley park, maybe a park in Kerala, India. It is located within the Nilgiri Hills, features a core area of 89.52 ${ Km }^{ 2 }$, which is surrounded by a buffer zone of 148 ${ Km }^{ 2 }$. This park has some rare species of flora and fauna. In 1847 by the botanist Robert Wight the area was explored.

Additional information
Silent Valley is home to the most important population of lion-tailed macaques, a species of primate. Public controversy over their habitat led to the establishment of Silent Valley park.
In 1973 the valley turned into the principal focus of "Save Silent Valley", India's fiercest ecological development of the most recent decade when the Kerala State Electricity Board chose to execute the Silent Valley Hydro-Electric Project (SVHEP) fixated on a dam over the Kunthipuzha River.
The resulting reservoir would threaten the lion-tailed macaque and flood 8.3 ${ Km }^{ 2 }$ of the virgin rainforest. In 1976 the Kerala State Electricity Board announced plans to start dam construction and therefore the issue was delivered to public attention. Romulus Whitaker, the founding father of the Madras Snake Park and therefore the Madras Crocodile Bank, was probably the primary person to draw public attention to the tiny and remote area.

So the correct answer is ‘Silent Valley National park’.

Note: Silent Valley gets copious measures of rainfall during the monsoons, yet the real sum fluctuates inside the area because of the shifted geology. In general, rainfall is higher at higher altitudes and decreases from the west to the east due to the rain shadow effect. Eighty percent of the rainfall occurs during the south-west monsoon between June and September. The park also receives a significant amount of rainfall during the north-east monsoon between October and November.
