Utah is located in the Intermountain West region. It has diverse terrain ranging from arid desert basins to humid mountain peaks. While most of Utah receives little rainfall, convection storms in the summer can cause flash flooding. The economy relies on livestock agriculture due to the climate and landforms. Federal land ownership accounts for most of Utah's land area. Utah has a long history dating back to dinosaurs and Native American cultures, and was settled in 1847 by Mormon pioneers seeking religious freedom. Popular tourist destinations include Canyonlands National Park, known for its red rock formations and rivers, and the Pioneer Memorial Museum which documents Utah's pioneer history.
