In the middle of nowhere Western Kansas off of US Highway 83, about 25 miles south of Oakley, is the Little Jerusalem Badlands State Park. It consists of Smoky Hill Chalk Badlands which are from the Cretaceous Period and are about 88 million years ago. They are the erosion of sea bed which is why so many marine animal fossils are found throughout the area. The white chalky walls create small tight canyons that reminded early visitors to the old city of Jerusalem. There are two trails at the park. There’s the 2.5 mile Life on the Rocks Trail and the .5 mile Overlook Trail. There are restrooms at the parking lot but they were locked in April when I was there which forced me to abstain from hiking. It’s very nearby the Keystone Gallery and the Monument Rocks.
