The glacial striations puts Kelleys in mild fame as inside are the largest and most easily accessible remains of glacial grooves in the world.

During the most recent millions of years multiple glaciations have covered the lake and its surroundings, leaving glacial striations and drumlins as they receded.

The park is built on a formation of Manhattan schist and contains interesting examples of igneous intrusions and of glacial striations from the last Ice Age.

A glacier later removed much of this mass of rock and left a polished surface on top of the columns with very noticeable glacial striations and glacial polish.
15.
Glacial striation and the presence of chalk and flint erratics that originated from the bed of the North Sea demonstrate the influence of ice action on the geomorphology of the islands.
16.
Evidence of the last ice age that ended less than 10, 000 years ago is abundant in the glacial striations found in the bedrock and the erratic granite boulders lying on the limestones.
17.
Glacial striations are usually multiple, straight, and parallel, representing the movement of the glacier using rock fragments and sand grains, embedded in the base of the glacier, as cutting tools.
18.
Evidence of past glaciers are visible throughout the park in the form of " glacial erratics " ( large boulders dropped by the receding glacier ) and north-south glacial striations visible on stone outcroppings.
19.
Other examples of glacial striations can be found in the former path of the Moiry Glacier, south of Grimentz, Anniviers, Valais, Switzerland, alongside the present path of the glacier, north-east of the 2016 location of the tongue of the glacier ( images ).

As they were transported down valley and later southward, the highly fractured boulders and other landslide debris were neither broken up into smaller blocks, rounded, nor marked with glacial striations because they were carried either on top or in the upper part of the glacier as it moved.
