I was on Diamond mountain the other day and the only diamonds I found were frost crystals on the sagebrush. Diamond mountain got it name as it was believed that there were diamonds there. It was not far away where diamonds were "discovered" by two crooks. These men brought moneyed men from the East, West on the transcontinental railroad. They left the train in Wyoming and headed South to near the Wymoming/Colorado border. They took them on horse back for several days in a round-about route and finally brought them to the place where they had cached the rough diamonds. They then began to find diamonds for their investors. A large amount of money changed hands and the diamond rush was on. The hoax was discovered by a USGS geologist that had made a geological survey thru that area. He could not believe how he had missed the diamonds. He came back to look at the area and disproved the diamond claim. This diamond hoax took place in the late 1800s. The people that homesteaded on Diamond mountain thought there were diamonds there also and so it got its name.
