Arapaho Glacier, Alpine glacier near North Arapaho Peak in Roosevelt National Forest, Colorado.
Arapaho Glacier is an alpine ice mass in Roosevelt National Forest below North Arapaho Peak. The ice covers steep slopes with visible cracks and dark stripes of rock and debris running across the white surface.
The glacier formed thousands of years ago during colder climate periods and was once far larger. Over the past hundred years it has shrunk significantly, reflecting how mountain climate patterns keep shifting.
The meltwater feeds streams that matter to the surrounding region and shows how high mountain water connects to communities below. Visitors can feel this link while moving through the landscape and see how glacier springs sustain life in the valleys.
Access comes through the Arapaho Glacier Trail, a multihourtrek with steep sections and open rock passages. Visitors should start early, bring sturdy footwear, and prepare for changeable weather at this elevation.
At the lower edge of the glacier sits an alpine lake fed by melt, which shifts slowly as the ice retreats. This proglacial lake offers a visible reminder of how much the glacier is transforming over time.
