March 1, 2019 Update
Nearly two feet of snow currently covers lower elevations in the monument with deeper amounts at higher elevations. Most of the unpaved roads in the monument are impassable and will remain so until the snow melts and road surfaces dry. Travel on unpaved roads in the monument when wet or snow covered is not recommended due to clay and soft soils. Weather can be extremely unsettled and variable at Dinosaur during the winter. A sunny, dry, day can quickly change to cold, windy, rainy or snowy. Temperatures my fall below freezing or even below 0ºF. Visitors should check the weather before heading out to explore and always let someone know about their plans.
