The mountaineous group of Paine called “macizo” (massif) consists mainly of sedimentary and granite rocks, standing out above the region with its maximum elevation of 3050 m.s.n.m.  This mountain was formed 12 millions years ago (as a reference, the Andes Range of Mountains is 60 millions years.

From a geological point of view, the landscape of the National Park is considered new.

The relief had its origin in geological phenomena which combined the upheaval of the Paine Range of Mountains with the erosive action of the glaciation with its advances and reverses

The evidences of ecological evolution of the area are summarized as follow:

- Oceanic Flood	150 millions years ago.
- Upheaval of the Patagonian Andes	65 a 13 millions years ago.
- Upheaval of the Mountain Range or Massif Paine	12 millions years ago.
- Glaciation	3.5 millions until the 14.000 years ago.

This territory is amazingly beauty.  It allows visitors to observed old formation of rocks of 150 millions years as well as others of 60 millions years ago.  Other geological curiosity is found between the crossing Laguna Amarga and Pehoe, where small hills in a dome-shape that experienced big pressures thousands of years ago.

The Mountain Range of Paine emerges from sea level to stand out above with its unreal figure landscape of the Park.

The difference of colour that the rocks have are due to the granite (light grey) and sediment (black colour).  The highest point of this mountain is in the Paine Grande hill whose summit reaches to 3.050 m.s.n.m.; being the highest hill of the Ultima Esperanza province.
