Climbing History (Longs Peak)



Title: First Documented Ascent:

On August 23, 1868, a party led by John Wesley Powell, which included newspaperman William Byers, reached the summit via the south side after a long approach from Grand Lake. Testimony of an old Arapaho Indian in 1914 indicated that the peak had been climbed previously by an Indian named, "Old Man Gun," who had trapped eagles on its summit.
After the first documented ascent, two prominent people emerged in the history of Longs Peak-Reverend Elkanah J. Lamb and Enos Mills. Lamb made his first climb of Longs in 1871 and then made the first descent of the east face via a couloir now know as Lambs Slide, appropriately named because the Reverend quite inadvertently made much of the descent on his seat instead of his feet.

Title: Geology of Longs Peak

Entered by: rockdoc53

Longs Peak was formed about 1.4 billion years ago as magma intruded older (1.7 billion years) metamorphic rocks forming the Longs Peak-St.Vrain batholith. The intrusion is composed mostly of the Silver Plume Granite, which is a light to medium gray monzogranite to syenogranite with distinctive tabular microcline (feldspar) phenocrysts.

A prominent horizontal band of metamorphic rock (biotite schist/gneiss) is exposed on the north, west and south faces of Longs Peak above 13,200 feet, and the Keyhole route crosses the band on the west side.

Title: Naming of Longs Peak

Added: 05/14/2010, Last Updated: 05/14/2010

Sources: Hart, J.L.J. (1977). Fourteen thousand feet: A history of the naming and early ascents of the high Colorado peaks (Second Edition). Denver, CO: The Colorado Mountain Club.

Longs Peak and its southern neighbor, Mt. Meeker (13,911 ft.), were called "Nesotaieux" (The Two Guides) by the Arapaho Indians and were known as "Les Deux Orielles" (The Two Ears) by early French fur traders. The mountain takes its name from Major Stephen H. Long (1784-1864), whose expedition made the first recorded sighting of the peak on June 30, 1820.
