Issue Date 4-7-2018

Location:M-DT open to hikers around the gate at Grace Plateau just West of Highpoint Scenic Vista.

Comments: We’ve recently have had a couple hikers concerned about some owner placed signage at our trail location near Highpoint Scenic Vista and Grace Plateau on Map 3. There is a gate that you need to walk around but we do have permission from the new land owners to be here. You will see a sign on the gate asking all visitors to buzz in, but this is not meant for hikers. You will notice a sign that says there is video surveillance and other no trespassing signs that can be a little intimidating. As long as you are hiking through and staying on the trail you are permitted to do so. Please do not buzz in because staff working at the facility may not even know about the trail and we do not want to become a nuisance. Our blazes are very easily seen and you will see the post indicating the wishes of the property owner where you divert from and onto their private drive.

Map 4- Trinity Church Road South of Wrightsville, PA to Otter Creek Campground, PA.

Issue Date: 09-25-2018
Location: The M-DT along Otter Creek between Kline Rd & Otter Creek Campground has difficult footing in spots.
Comments:The M-DT is open between Kline Road and Otter Creek Campground but the trail along Otter Creek has been damaged by washouts, downed trees and flood debris. The footing will be more difficult in these areas because of sand washed onto the trail or bare rocks where the trail bed was washed away.

Map 10- White Clay Creek Preserve at London Tract Road, DE to Chadds Ford, PA. 


Issue Date: 2020 Onward

Location: M-DT detoured onto roads around State Line Woods.

Comments: The Mason-Dixon Trail is currently re-routed around the Stateline Woods Preserve (SWP). The previous connection between Auburn Valley State Park in Delaware and Stateline Woods in Pennsylvania was on private land that was posted "no trespassing" recently. In response, the trail had to be re-routed along roads around Stateline Woods. (It does, however, now pass a craft brewery!) We are hopeful that future public/preserved land acquisitions in the area will allow a new connection between Auburn Valley State Park and Stateline Woods in the next few years. For the time being, the Mason-Dixon Trail is detoured on the blue route above from the Paper Mill Parking Lot on Benge Road to the intersection of 9 Gates Rd and Fassett Dr.
