The Cultural Resource program in the Bureau of Land Management’s Monticello Field Office is divided into two sub-programs: Archeology and Paleontology. Many people come to the Monticello Field Office to see its heritage resources, especially archeological sites. People come from all over the world to see areas like Grand Gulch, where some of the earliest archeological research was conducted. Throughout this area Ancestral Puebloan Native Americans left a legacy that includes hundreds of cliff dwellings and ruins and thousands of pictographs and petroglyphs. Less known heritage resources are paleontological discoveries. Heritage Tourism is a popular activity here.
