Palmer North is a simple and easy road through the Mark Twain National Forest and provides access to Parole Lake which is an old barite and lead mine. Barite, also spelled Baryte, is the main compound used in making barium. Barium is used in drilling mud, paint, glass, ceramics, and rubber. Barium sulfate is also used in medical tests and X-rays! The thick forest on either side of the track prevents seeing much until you get to the dam area, roughly the middle of the trail, where it opens up a little bit. No campsites are found on the road.
A small water crossing at the southern end with a culvert makes it uneventful except during heavy rain events.
