Glaciers

A brief history of glacial activity in the Grand Teton National Park, with a warning concerning the dissipation of the remaining glaciers.

An info-packed slideshow that gives an outline of glacial activity in the Teton Range. The slideshow details the categories of geological features left behind by glaciers, and informs viewers where they can find examples of those features in the park.

Glacier National Park: This audio file discusses Jackson Glacier as well as other glaciers in Glacier National Park. It is suggested that evidence for climate change can be seen with the melting of the glaciers in the park.

Glacier National Park: The value of research on glaciers is discussed by a USGS research ecologist. Emphasis is placed on how the melting of glaciers affects ecosystems and serves as an indicator for climate change.

Kenai Fjords National Park: Pictures of the glaciers at Kenai Fjords are compared in sequence. For instance, a picture of McCarty Glacier from 1909 precedes a picture of the same glacier in 2004. The video displays how the glaciers have receded over a century.

Kenai Fjords National Park: Experts track and discuss the rate at which Exit Glacier has receded over time. Methods of tracking the rate at which the glacier is receding are discussed as well as potential reasons the glacier is receding.

Kenai Fjords National Park: The video discusses how glaciers in Kenai Fjords serve as markers for climate change. It is discussed that the glaciers are indeed receding rapidly and what the park is doing to inform the public about the issue.

Yosemite National Park: Yosemite National Park is famous for its spectacular glacially carved landscape. Although glaciers have come and gone many times in the past, there are still two active glaciers near Yosemite's highest peaks.
