Pikes Peak granite is a 1.08 billion year old Late-Precambrian geologic formation found in the central part of the Front Range of Colorado.

Over the next 450 million years, the area was covered by seas, reefs, beaches, sand dunes and mountain streams which laid down more than 15,000 feet (4,500 m) of sediment.

About 60 million years ago, parts of the Western U.S. were subjected to a series of uplifts, known as the Laramide orogeny, that eventually formed the modern Rocky Mountains and raised Pikes Peak to its current height.

Pikes Peak, like other portions of Colorado Rockies is still being uplifted today as a part of larger tectonic processes affecting the Western United States.

Today, the Pikes Peak Batholith and Granite is exposed over a large part of the central Front Range of Colorado.

Geologists have found the granite at the bottom of deep wells on the plains and magnetic sensors have detected it as much as 80 miles (130 km) to the east.

Almost every hill and slope in the Pikes Peak region is covered with thick blankets of loose gravel (scree) made up of marble-sized grains of feldspar.

The chemistry of the cooling magma produced a complex and unique mineralogy that attracts collectors from around the world and the Pikes Peak region is famous for its spectacular mineral specimens.
