South Cascade Glacier, northwestern Washington State
South Cascade Glacier, northwestern Washington StateSouth Cascade Glacier, northwestern Washington State. South Cascade Glacier located in a north-northwest facing valley near the crest of the Cascade Range in northwest Washington state. In 1959 scientists with the USGS began collecting mass balance data on South Cascade Glacier, now one of five "benchmark glaciers" in the US.

Lemon Creek Glacier in the spring
Lemon Creek Glacier is located in the high-latitude maritime region of Alaska, at the southernmost tip of the Juneau Icefield. Glacier observations began at this site in 1953.

Marine Terrace Soil at Wilder Ranch State Park
Marine terrace soil at Wilder Ranch State Park near Santa Cruz, California. Here at the bottom of the pit, 64 inches (160cm), the colors have different mineralogy and chemistry from one another, these changes have been formed by root processes over 90,000 years of soil development.
