 Known to the Rappahoe Indians as land of the earthworm spirit, the interesting rock formations at Vitavu are the westward traveler's gateway to the Medicine Bow National Forest. Vitavu's characteristic rock outcrop is made up of 1.4 billion-year-old Sherman granite. These rocks represent some of the oldest rock in Wyoming, but are still more than a billion years younger than the Tetons. The hard granite of Vitavu is made up of large crystals of quartz, volcanic rock, and some mica. It is more erosion-resistant than the other surrounding material, resulting in these unique wind and water-sculpted forms. The natural erosion processes still take place today. Outdoor enthusiasts come from all parts of the world to sample the area's natural beauty. Climbers find some of the best wide-crack climbs in the world. There are over 900 routes currently on record. Vitavu is also a great place for pictures of beautiful sunsets, unique formations and colors, flowers, and wildlife. So the next time you visit the land of the Earthborne Spirit, remember to take your camera along to capture memories of your cliff climbs and the breathtaking scenery from the University of Wyoming Extension, I'm Ash LeGarles, exploring the nature of Wyoming.
