However, wood frogs in Interior Alaska exhibit even greater tolerance, with some of their body water freezing while still surviving. Wood frogs in natural hibernation remain frozen for 193 +/- 11 consecutive days and reached an average (October–May) temperature of −6.3 °C (20.7 °F) and an average minimum temperature of −14.6 ± 2.8 °C ...

The Alaskan waters are home to two species of turtles, the leatherback sea turtle and the green sea turtle. Alaska has two species of frogs, the Columbia spotted frog and wood frog, plus two introduced species, the Pacific tree frog and the red-legged frog. [1] The only species of toad in Alaska is the western toad.
The Alaskan Range is part of the topography in the Yukon River Basin. The mountains range from 6,000 to 9,000 feet (1,800 to 2,700 m) in elevation. The Yukon River Basin is approximately 330,000 square miles (850,000 km 2) in area and 1,980 miles (3,190 km) in length. [1] This makes the Yukon River Basin the fourth largest basin in North America.
Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (Lithobates sylvatica)—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole ...
Fossilised Arctic ground squirrel nests and caches have also been used for palaeoenvironmental reconstruction; Calamagrostis canadensis, Carex albonigra, and Koeleria sp. are common in caches from Late Pleistocene Alaska, indicating the presence of an aerially extensive mammoth steppe ecosystem in the region at this time.
