Passage: Seed spent the 1914–15 season playing in Sunderland reserves, he scored plenty of goals as the team lifted the Durham Senior Cup. Official League football was suspended at the end of that season because of the outbreak of World War I. At the end of the season, the 20-year-old Seed joined the Army Cyclist Corps. In the summer of 1916, he was drafted to France with the 8th battalion of the West Yorkshire Regiment. Seed suffered with depression after his arrival and in July 1917, he was gassed when a German aeroplane dropped mustard gas bombs on a house in Nieuwpoort, Belgium, in which he was sleeping. He returned to England to convalesce and returned to France in August 1918, until being evacuated after being gassed in Valenciennes, France two months later. With the cessation of hostilities, Seed played a Victory League match for Sunderland against Durham City in 1918, however his lungs were weak and he had a poor game. On the strength of that performance the Sunderland directors decided that Seed's wartime experience had finished him as a footballer and gave him a free transfer. Seed never played an official first team game for Sunderland. Seed was discharged from the army in March 1919.

The pass provide access into three river sheds. An east-west route ran from the east up the Wind River valley and provided a western route by the Gros Ventre or Hoback Rivers to the Valley of the Snake River in Jackson's Hole.

Passage: In modern times, the creation of relatively simple dome-like structures has been documented among various indigenous peoples around the world. The wigwam was made by Native Americans using arched branches or poles covered with grass or hides. The Efé people of central Africa construct similar structures, using leaves as shingles. Another example is the igloo, a shelter built from blocks of compact snow and used by the Inuit people, among others. The Himba people of Namibia construct "desert igloos" of wattle and daub for use as temporary shelters at seasonal cattle camps, and as permanent homes by the poor. Extraordinarily thin domes of sun-baked clay 20 feet in diameter, 30 feet high, and nearly parabolic in curve, are known from Cameroon.
