Incombe Hole :: Shared Description

Incombe Hole is a dry valley to the south of Steps Hill on the Ashridge Estate (National Trust) at the northern end of the Chiltern escarpment.
This dry valley was created by a process called "nivation" - from the latin for snow - as it is an erosion geomorphological feature resulting from freezing and thawing, dating back to the Ice Age.
Firstly water freezes within the cracks, holes and fissures in the rock resulting in the rock fracturing, this is known as gelifraction. The second stage occurs due to gravity dragging the fractured rock particles down the slope of the hill, scoring the valley into the hillside as it descends with the ice and snow. This process is called solifluction. At the end of the Ice Age, the ice and snow disappeared leaving the dry valley that we see today with no stream or river at its valley floor.
