The topographic map is on the scale of 660 pixels/mile.
The boundary of the park is marked by a yellow dotted line. This boundary information is taken from the Fairfield County Tax Maps. There is also a 40 acre parcel marked with an orange dotted line. This is a parcel that was forfeited to the state; the Lancaster Park System is currently working on acquiring that property.
