Brutus, a wolf being studied by USGS scientists, separates from his pack mates and appears to be heading back to the den. He stops at the head of the fiord and howls for 2-3 minutes. The scientists track his progress with binoculars past the river where they cannot go. They suspect that his mate has returned to the den, and that Brutus will join her there.

Brutus, a wolf being studied by USGS scientists, is chemically immobilized, measured, ear-tagged, and fitted with a radio collar near the Eureka airstrip on Ellesmere Island in the High Arctic, Nunavut, Canada.

Native Americans of the Miwok tribe in the northern Sierra Nevada, California carved these basins into the granite bedrock to produce salt for trade. They filled the basins with water from a salt spring and let the water evaporate, leaving a salt residue in the basin.

An American Alligator in Everglades National Park. The species was once listed as Endangered, but was removed in 1987 after a successful recovery.

American crocodiles are restricted in their range within the USA to southern Florida. Decisions on restoration of the Everglades must incorporate protection for this threatened species.
