Current Conditions




We try to update this page in a timely manner, however, due to the range in elevations and soil types for our roads and trails, conditions can change rapidly in Dinosaur National Monument. The Echo Park and Island Park Roads often become impassable after a rain storm. During winter, some areas may receive heavy snow while others are clear and dry. If you are headed into the park and would like additional information, please call the visitor center at (435) 781-7700 or email us.


August 30, 2018 Update
Weather can be extremely variable at Dinosaur during the summer months. A hot, dry, day can quickly change to windy and rainy. This is especially common during the monsoon season, July through August, when storms can drop an inch of rain in one location, while another place a short distance away is left dry. Visitors should check the weather before heading out to explore. Travel on unpaved roads in the monument after a rainstorm is not recommended due to clay and soft soils that have the consistency of peanut butter on road beds.
