[2] Due to its close proximity to the Coquihalla Highway, the mountain attracts skiers to its slopes in winter.

[4] During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.

Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area.

As a result, the Cascade Mountains experience high precipitation, especially during the winter months in the form of snowfall.

The months July through September offer the most favorable weather for climbing Thar Peak.
