Roads of Tennessee - A Collection of Top Ten Lists

Highway 30, Van Buren County, Tennessee I found myself on a long, lonely road a few weeks ago. It was River Canyon Road that crosses from Marion County to Hamilton county as it follows the course of the Tennessee River through the Tennessee River Gorge. As I drove this road, I wondered, "Is this the longest segment of road without any intersections in the state?" I have the data and tools to solve this problem.

First, let's look at River Canyon Road. As I look at my data, I can see that it is broken up with several named and unnamed smaller roads that lead off from it. However, my intuition wasn't far off base. It's combined segment lengths between intersections (not spurs) is 18.93 miles. However for the purpose of this analysis, it will not appear again.

Longest Road Stretches between Intersections
1) Cold Spring Rd, Monroe County - 15.12 miles
2) Game Reserve Rd, Marion County - 11.82 miles
3) Lower Pain Creek Rd, Greene County - 10.07 miles
4) Meadow Creek Rd, Cocke County - 9.52 miles
5) Pace Gap Rd, Polk County - 9.51 miles
6) Howard Harrison Rd, Carter County - 9.22 miles
7) Richland Coal County Rd, Scott County, 8.88 miles
8) Big Sycamore Creek Rd & Snake Hollow Rd, Claiborne & Hancock Counties, 8.79 miles
9) Miss Kelly Loop, Dyer County - 8.40 miles
10) River Rd, Monroe County - 8.04 miles

Longest Stretch of Road under the Same Name
1) Interstate 40, 911.61 miles
2) State Highway 1, 711.18 miles
3) US Highway 70, 620.47 miles
4) US Highway 64, 567.55 miles
5) Interstate 24, 363.45 miles
6) State Highway 15, 351.46 miles
7) Interstate 75, 318.17 miles
8) Lee Hwy, 302.89 miles
9) US Highway 321, 279.77 miles
10) State Highway 76, 276.87 miles

Missing People Map

Image
Sometime around middle to late November of 2019, I started getting tagged in posts on Reddit and Facebook where a map purported to show a correlation between missing person cases and caves. The two maps in question were of terrible quality in both content and image quality (so very much JPG compression). Somehow these maps managed to capture the public's attention for several weeks. In fact, more than two months later I am still being asked questions about the map. What follows is a critical analysis of the maps from both a cartographer's perspective, as well as a caver's. Origin Where did each image come from that comprised the map? The top image is titled " North America Cluster Map " and is produced by the Canam Missing Project / Missing 411. I cannot comment on the methods used to produce the map since they aren't stated. For this reason I am immediately suspect that this is conveying real information. I'll touch on why the form of this ma...

Sandstone Boxwork

Photo credit: Brian Solomon / @waterfall_hillbilly Photo credit: Bryan Melton Sandstone boxwork is a unusual phenomenon that we see on the margins of the Cumberland Plateau. There are three things that must happen first to produce boxwork. Jointing Mineralization Weathering Jointing Produced in a parent rock of sandstone, this type of boxwork originates as small joints which run in a box shape. The origins of these joints could be from frost wedging - where water in the rock freezes and cracks the rock, or it could unloading pressure from the rock de-watering, or it could be from some other physical process. The origins of the boxwork joints are still a bit of a mystery. If the following steps occur without previous jointing then one gets Liesegang Rings. Mineralization The joints become a place of preferential mineralization. Groundwater loaded with iron minerals moves through the pores of the sandstone. Where it finds a void, like...
