Winter Bivouac

“In constructing the nightly bivouac each set of two or three men would dig a hole seven or eight feet square down to the ground. A bed of soft pine twigs was laid and over this a blanket was spread. On the windward side two forked sticks were stuck in the snow and against these a windbreak of pine boughs was constructed. With a fire made in the snow pit the night was passed with a fair degree of warmth.”
