At the northwest corner of Delaware, where it meets Pennslyvania & Maryland, is the “Tri-State Marker”. It was first located by Mason and Dixon back in 1765, though the marker was placed later, in 1849. I learned pretty much everything I know about it from this newspaper article from 2015: https://www.newarkpostonline.com/news/new-trail-provides-first-public-access-to-mason-dixon-tri-state-marker/article_a5ec3a04-fe1a-58d4-a317-93c3e887c863.html

I’ve hiked to the marker twice this year, from Delaware's White Clay Creek State Park starting at the Chambers House Nature Center parking lot. It’s about a 3.5 mile roundtrip, meaning an hour and a half walk for me. I walk slow, and stop to look at things a lot. I had the path mostly to myself when I hiked it Friday afternoon, saw just 6 others in the 1.5 hours I was walking.

I understand you can also walk to the monument through other shorter pathways, but I haven’t done so. That’s an adventure for another time.

Note: The Chambers House nature center is also the location of one of the Selfie spots for the Delaware State Parks passport program. It's still closed due to COVID, but I saw some staff heading in to work. They arehoping to repoen in January. They gave me a map, and seemed to think the walk to the monument was "far". 

Trip start

OUTBOUND

Trail is mostly wooded trees, but it does open up to a field or two upon occasion. You cross from Delaware to Pennsylvania pretty early in the hike. And yeah, I bough hiking boots (Merrells). Last time I hiked this in the Spring, I had just bought hiking sandles (Tevas), which I love. But it's getting too crisp for sandles.

THE MONUMENT

I later learned (from reading that article above) that the monument has no D because in Mason-Dixon's time, Delaware was still part of Pennsylvania. Hence 2 P’s , 2 M’s no D.

THE WAY BACK

On the way back you cross into Delaware, then back into Pennsylvania, then back into Delaware.  Also, there is a peace love & happiness tree (Yo peeps: don't graffiti trees, even with nice sentiments). I understand there is a CAVE near one of these PA/DE borders, on the PA side. Something to look for next time.

So, pretty easy hike, cool historical marker, not crowded. Recommended.

A beautiful day for hiking. If you ever lack things to look for, https://www.geocaching.com has thousands, including https://www.geocaching.com/geocache/GC1EN31 in White Clay Creek State Park.

I just today learned about letterboxing. Which sounds like fancy geocaching... I might give that a try

Yeah, letterboxing long predates the practice of "using multi-million dollar satellites to find Tupperware in the woods".
