#OnThisDay in 1964, CanyonlandsNPS officially became part of the national park system. This southeastern Utah park welcomes an average of 500,000 visitors each year. Have you ever been? #FunFact: Mesa Arch, pictured above, is one of the most photographed arches in southeast Utah. This location is especially popular at sunrise when groups of photographers wait for the sun’s rays to hit on the bottom of the arch. #NationalParks #Parks #Utah #MesaArch
