The letters are still used, but some site designations have changed. This is from another forum (posted July 08 2016): "........A new overnight trailhead on Shea Road has been established near the Hope Schoolhouse. The parking area on SR 278 is now for day hiking only. Camp D is now I and H is now P. Out and back, the new section adds about 3 miles to the south loop. ODNR has updated their map: http://forestry.ohiodnr.gov/zaleski"
