It seems someone really really wanted the Delicate Arch model I created years ago that the National Park Service at Arches National Park recreated in a durable metal and installed near the trail head in the very popular national park.
This tactile model helped people that were unable to see the arch or make the hike still understand the beauty of the natural arch. Hopefully the thief gets caught, but also a new one replaces it, and nobody steals that one.

I love Delicate Arch, and have photographed and hiked it many many times in all seasons, but also scanned it with LiDAR.
In 2012, I organized the first laser scan of the Delicate Arch with a couple employees of FARO Jeff Squibbs and Matthew Daly. 
My pitch was everyone can scan a building, a bridge, or most manmade structures, but organic natural sandstone arches would create complexity in the point cloud capture and be a fun challenge to show difficult things can be captured and made into 3D models and document natures ever changing items. These sandstone arches are always changing in the same way they were created by erosion from wind, water, ice, and temperatures. After the scan and a lot of time converting the billions of points into a 3D watertight model, I started 3D printing a low resolution and a high resolution model and also a chocolate model using a food grade latex mold.
I then delivered an accurate 3D print to the NPS Ranger in charge of Arches National Park at the time, and then arranged to transfer the massive data files to the NPS archives for their use.
The NPS staff were amazed at the detail since I used both LiDAR and some photogrammetry to create the accurate model. The large delicate arch in the visitor center was an artist representation of the arch, but wasn’t completely accurate like the model from the scan. I was told by the NPS they were going to use my model to create a tactile model for those with sight problems or unable to make the hike to the iconic sandstone arch as well as have accurate details on the arch at a point in time to preserve its history and understand how it changes with each year. I was told the main force at work on the arch is not really the wind, but in the winter when water seeps into the sandstone then freezes and expands causing fissures and sluffing.
