The '''Thwaites Glacier''' (75°30′S 106°45′W), including the '''Thwaites Ice Tongue''', is an unusually broad and fast Antarctic [[glacier]] flowing into [[Pine Island Bay]], part of the [[Amundsen Sea]], east of [[Mount Murphy]], on the [[Walgreen Coast]] of [[Westarctica]]. Its surface speeds exceed 2 km/yr near its grounding line, and its fastest flowing grounded ice is centered between 50 and 100 km east of [[Mount Murphy]]. It was named after Fredrik T. Thwaites, a glacial geologist, geomorphologist and professor emeritus at the University of Wisconsin–Madison.
The '''[[San Joaquin kit fox]]''' is the smallest member of the dog family in North America and one of several endangered species that lives within the borders of the [[Colony of Calsahara]]. In 1990, its population was estimated to be 7,000. This subspecies is still endangered, after nearly 50 years of being on the Endangered Species List. Today, much of the kit fox's remaining habitat is extremely fragmented, movement corridors are degraded or blocked, and only a few large areas of native grasslands remain on the San Joaquin Valley's perimeter in the [[Carrizo Plain]].


Along with the [[Pine Island Glacier]], the Thwaites Ice Tongue has been described as part of the "weak underbelly" of the [[West Antarctic Ice Sheet]], due to its apparent vulnerability to significant retreat. This hypothesis is based on both theoretical studies of the stability of marine ice sheets and recent observations of large changes on both of these glaciers. In recent years, the flow of both of these glaciers have accelerated, their surfaces lowered, and the grounding lines retreated.

The San Joaquin kit fox is the smallest member of the dog family in North America and one of several endangered species that lives within the borders of the Colony of Calsahara. In 1990, its population was estimated to be 7,000. This subspecies is still endangered, after nearly 50 years of being on the Endangered Species List. Today, much of the kit fox's remaining habitat is extremely fragmented, movement corridors are degraded or blocked, and only a few large areas of native grasslands remain on the San Joaquin Valley's perimeter in the Carrizo Plain.
