Ice age
An ice age or, more precisely, glacial age, is a generic geological period of long-term reduction in the temperature of the Earth's surface and atmosphere, resulting in the presence or expansion of continental ice sheets, polar ice sheets and alpine glaciers...

The canyon begins at the summit of Mount Fitzgerald at an elevation of 11,215 feet (3418 m), and quickly descends to its nearly level upper section. It is here that the greatest evidence for glacial sculpturing can be found. The canyon shows a classic U-shaped cross section, and many patches of bare granite still retain the dark patina and striations
Glacial striations
Glacial striations or glacial grooves are scratches or gouges cut into bedrock by process of glacial abrasion. Glacial striations usually occur as multiple straight, parallel grooves representing the movement of the sediment-loaded base of the glacier...

, the canyon then makes a dramatic drop and sharp turn to enter its lower section. Near here are visible a large geologic fault
Geologic fault
In geology, a fault is a planar fracture or discontinuity in a volume of rock, across which there has been significant displacement along the fractures as a result of earth movement. Large faults within the Earth's crust result from the action of tectonic forces...

in the granite wall of the canyon, a steep cascade of the stream flow, and, further down, a 30 foot (10 m) falls. Having descended to an elevation of 7100 feet (2165 m), the canyon finally passes Camp Lamoille and merges with the main branch of Lamoille Canyon.
