Rise at Orangeville

From Wikipedia, the free encyclopedia

For other places with the same name, see Orangeville.

Orangeville Rise is the second largest spring in the United States state of Indiana. It is also a National Natural Landmark. Contrary to popular belief, the spring is not the rise of the Lost River which actually surfaces approximately 2 miles south of Orangeville. Water emerging at Orangeville Rise comes from approximately 48 square miles of the highly karstified Mitchell Plain to the northeast. The spring fluxuates wildly in response to drought and rain events, with storm discharge appearing less than 24 hours following an event.
