ConTeXt is a general-purpose document processor. It is especially suited for structured documents, automated document production, very fine typography, and multi-lingual typesetting. It is based in part on the TeX typesetting system, and uses a document markup language for manuscript preparation.
Wolves are common over much of the state. The highest densities occur in Southeast Alaska, where Sitka black-tailed deer serve as the major food source for wolves. Wolf densities are lowest in the coastal portions of western and northern Alaska.
For most of the year, the arctic wolf habitat is covered in thick ice. Unlike their cousins, the grey wolves and timber wolves who live further south in warmer climates, the arctic wolves are unable to dig through the frozen ground to create dens. For this reason, they shelter in caves and outcrops and among trees.
