Cholera outbreaks and pandemics
That year, cholera was transmitted along the California, Mormon and Oregon Trails as 6,000 to 12,000 are believed to have died on their way to the California Gold Rush, Utah and Oregon in the cholera years of 1849–1855. It is believed more than 150,000 Americans died during the two pandemics between 1832 and 1849.
Ezra Meeker
Meeker became convinced that the Oregon Trail was being forgotten, and he determined to bring it publicity so it could be marked and monuments erected. In 1906–1908, although in his late 70s, he retraced his steps along the Oregon Trail by wagon, seeking to build monuments in communities along the way. His trek reached New York, and in Washington, D.C. he met President Theodore Roosevelt. He traveled the Trail again several times in the final two decades of this life, including by oxcart in 1910–1912 and by airplane in 1924. During another such trip, in 1928, Meeker fell ill but was succored by Henry Ford. On his return to Washington state, Meeker became ill again and died there on December 3, 1928 at age 97. Meeker wrote several books; his work has continued through the activities of such groups as the Oregon-California Trails Association.
