Another formation near the previously mentioned Wildcat Hills are Jail and Courthouse Rock, butte formations from the same eroded escarpment. They are located near the town of Bridgeport, Nebraska.

JAIL AND COURTHOUSE ROCKS – were the first imposing landmarks seen by pioneers in their trek along the Oregon and Mormon trails. Located near Bridgeport, theses wind carved sentinels were named by travelers for their similarity to a jail and court-house they remembered near their eastern homes.

This card likely dates from the 1950s.
