Passage: Getty Square is Yonkers' downtown and the civic center and central business district of the city. Much of southwest Yonkers grew densely along the multiple railroads and trolley (now bus) lines along South Broadway and in Getty Square, connecting to New York City. Clusters of apartment buildings surrounded the stations of the Yonkers branch of the New York and Putnam Railroad and the Third Avenue Railway trolley lines and these buildings still remain although now served by the Bee-Line Bus System. The railroad companies themselves built neighborhoods of mixed housing types ranging from apartment buildings to large mansions in areas like Park Hill wherein the railroad also built a funicular to connect it with the train station in the valley. This traditionally African-American and white area has seen a tremendous influx of immigrants from Mexico, Central America, the Caribbean, South Asia, and the Middle East. Off South Broadway and Yonkers Avenue one can find residential neighborhoods, such as Lowerre, Nodine Hill, Park Hill, and Hudson Park (off the Hudson River) with a mix of building styles ranging from dense clusters of apartment buildings, blocks of retail with apartments above, multifamily row houses, and detached single-family homes.

Passage: Major Long's 1823 expedition up the Minnesota River (then known as St. Peter's River), to the headwaters of the Red River of the North, down that river to Pembina and Fort Garry, and thence by canoe across British Canada to Lake Huron is sometimes confused with his initial expedition to the Red River in modern-day Texas and Oklahoma. The expedition to the Red River of the North was a separate, later appointment which completed a series of explorations conceived of by Lewis Cass and implemented by David B. Douglass, Henry Schoolcraft, and others besides Major Long. The 1823 expedition was denoted primarily as a scientific reconnaissance and an evaluation of trade possibilities, but probably had undisclosed military objectives as well, and certainly was viewed with suspicion by British authorities in Canada. This expedition for a time was joined by the Italian adventurer Giacomo Beltrami, who argued with Long and left the expedition near Fort Garry. The 1823 expedition encouraged American traders to push into the fur trade in Northern Minnesota and Dakota, and fostered the development of the Red River Trails and a colorful chapter of ox cart trade between the Red River Colony and Fort Garry via Pembina and the newly developing towns of Mendota and St. Paul.
 Link Information:  On June 19, 1852, acting upon a request from the Minnesota territorial legislature, the United States Congress decreed the aboriginal name for the river, Minnesota, to be the river’s official name Question: When did the river in which Major Long took an 1823 expedition change it's name?
