Alta Township was secured from McPherson County. Each township in the new Harvey County received its name for a reason. Alta is one of four townships with a name chosen to honor or memorialize an individual. Alta was the name of the deceased daughter of Judge R.W.P. Muse, an early settler and prominent figure in the establishment of Harvey County. Located in Alta Twp was the now non-existent settlement of Alta and the site of Alta Mill. In the early years, a post office called Valentine served the community from a small office in the Alta Mill. Later, the post office’s name was changed to Alta. Alta and Garden Townships were originally settled by several French and Irish families who homesteaded on the Little Arkansas River and at the mouth of Turkey Creek in the fall of 1869 or the spring of 1870.
