The story

How Hinsdale came to be

From Wikipedia’s history of Hinsdale.

Read it all →

Native American tribes lived in the local area for thousands of years before European colonization. This colonization brought horses which greatly improved life on the prairie. The steady eastward march of settlers pushed new tribes into the area.

The Corps of Discovery reached the head of the Milk River in May 1805. There, the river received its name, for "the water of this river possesses a peculiar whiteness, being about the colour of a cup of tea with the admixture of a tablespoonfull of milk."

After the Corps of Discovery, the next major event in the area was the arrival of Texas cattle coming to fatten up on the local grass after their long cattle drives. The cattle drives lasted from 1866 until the late 1880s.
