Custer South Dakota

We were here 23 years ago with Nick and Karen, but we must have stuck to the kid friendly attractions as there are several items of interest that have been here forever that we missed, as well as some I had wanted to check back on. I thought I was going to check in on the progress of the Crazy Horse Monument, but when spotted, it looked exactly to me like it did 23 years ago. I guess a close up inspect won’t be necessary.

The Crazy Horse Monument is being sculpted by the heirs of Gutzon Borglum, the man who is best known for sculpting the Mount Rushmore National Memorial. Since we just did a scenic road trip on our first day in the area, there was no reason not to do a drive by!
Setting our itinerary a year ago, I saw a small point on the Rand McNally atlas map indicateng that the geographic center of the United States was just North of Belle Fourche South Dakota. While not terribly close, we decided it was worth adding to our initial scenic drive.
In 1912 the US Geological Survey established a point about 3 miles Northwest of Lebanon Kansas as the geographic center of the US. It stood as that marker until 1959, when Alaska and Hawaii were made states. Admitting those states reset the geographic center of the US to where we headed today.
Not many folks ever go here. Since the highway that ran by the site was rerouted, a visit requires an 8-mile drive on a very remote dirt road. Luckily the farmer who owns the land has made sure that folk who want to visit are able. We hiked a bit out into his field and found the actual USGS marker positioned at the exact geographic center of the US. How cool!
Why we didn’t visit the nearby National Monument while we were here 23 years ago I can’t recall. Established by Theodore Roosevelt with many of his other Western monuments, is the Jewel Cave National Monument.
We toured this interesting cave, and learned that where we were walking likely didn’t exist last time we were here. Until relatively recently, the only touring of Jewel Cave was through the one and only surface opening that has been discovered in the first couple centuries of exploration. In the last couple decades, an elevator shaft was sunk into the center of some very large rooms that has resulted in visitors being able to visit some more spectacular portions of this massive cave system.
Jewel Cave is believed to be the 3rd longest system of connected caves in the world, at over 190 miles of explored caves. Mammoth Cave in Kentucky, which we visited last time we were out East, is the longest at over 400 miles of explored caverns. All of the 400 miles of Mammoth Cave have been explored, while perhaps less than 5% of the estimated 190 miles of Jewel Cave have been explored. The primary reason is that the Mammoth Cave system has been fully explored is because there are more than a couple dozen natural entrances that made exploration much easier.
There is only one in Jewel Cave, and luckily it was on the Canyon Trail we hiked. Having only one entrance meant that explorers would take days just to venture further into the cave system. Packing in and out everything they needed meant that their exploration ventures could only be 4 or 5 days in duration. What that means is that Jewel Cave may be much larger than its current estimate. For example, since last November about 20 miles of actual mapped caves have been added to the system map. We will definitely check back on this and keep track of its progress.
Talk to you soon!
