Document 7: 1916 Republican National Convention: The 1916 Republican National Convention was held in Chicago from June 7 to June 10. A major goal of the party's bosses at the convention was to heal the bitter split within the party that had occurred in the 1912 presidential campaign. In that year, Theodore Roosevelt bolted the GOP and formed his own political party, the Progressive Party, which contained most of the GOP's liberals. William Howard Taft, the incumbent president, won the nomination of the regular Republican Party. This split in the GOP ranks divided the Republican vote and led to the election of Democrat Woodrow Wilson. Although several candidates were openly competing for the 1916 nomination—most prominently conservative Senator Elihu Root of New York, Senator John W. Weeks of Massachusetts, and liberal Senator Albert Cummins of Iowa—the party's bosses wanted a moderate who would be acceptable to all factions of the party. They turned to Supreme Court Justice Charles Evans Hughes, who had served on the court since 1910 and thus had the advantage of not having publicly spoken about political issues in six years. Although he had not sought the nomination, Hughes made it known that he would not turn it down; he won the nomination on the third ballot. Former Vice-President Charles W. Fairbanks was nominated as his running mate. Hughes was the only Supreme Court Justice to be nominated for president by a major political party. Fairbanks (as of 2016) was the last former vice president, to be nominated for vice president.

Document 14: Dusty Glacier: Dusty Glacier is located on northeast slopes of Glacier Peak in the U.S. state of Washington. The glacier descends from 9022 ft to 6430 ft and in places along its length is connected to North Guardian Glacier which lies to its south and Ermine Glacier to the north. As is true with all the glaciers found on Glacier Peak, Dusty Glacier is retreating. During the Little Ice Age, Dusty Glacier extended down to an altitude of 4800 ft , but since approximately the year 1850, the glacier has been in a general state of retreat and has lost more than 1500 m of its length. Dusty Glacier is heavily crevassed and the glacier ends in an ice fall at its terminus.

Like all the glaciers in Olympic National Park, Fairchild Glacier has been in a general retreat for over 100 years. The glacier is named for William R. Fairchild, who was a pilot that assisted scientific researchers in the region.
