Ursina takes its name from Judge William J. Baer, owner of the land when the town was laid out in 1868 by surveyors H.L. Baer and R.J. Botzer; "bear" in Latin is Ursus.[4] Judge Baer had a blacksmith shop and a sawmill built, Ephraim Kreger built the first house, and Isaac A. Jenkins built the first store, all in that same year of 1868.[4] A school was built in 1870, with John Griffith serving as the first teacher.[4] Ursina was organized as a borough in 1872.[4]
The Ursina Branch Railroad was built by the Pittsburgh and Baltimore Coal, Coke, and Iron Company in 1871–1872 in order to more easily access the coal deposits in the area.[5] This four mile line only operated for about three years before the ongoing effects of the Panic of 1873 caused it to cease.[5]
The climate in this area has mild differences between highs and lows, and there is adequate rainfall year-round. According to the Köppen Climate Classification system, Ursina has a marine west coast climate, abbreviated "Cfb" on climate maps.[7]
