Petit Grepon is a semi-detached spire in Colorado's Rocky Mountain National Park. It is one of the "Cathedral Spires" which also includes: Sharkstooth, The Saber, and The Foil. The South Face route of Petit Grepon is described in the historic climbing text Fifty Classic Climbs of North America[3] and considered a classic around the world.[4]

Climate

According to the Köppen climate classification system, the spire is located in an alpine subarctic climate zone with cold, snowy winters, and cool to warm summers.[5] Due to its altitude, it receives precipitation all year, as snow in winter, and as thunderstorms in summer, with a dry period in late spring.
