Trump reduces Utah's Bears Ears and Grand Staircase-Escalante national monuments by approximately 90%

On July 13, 2026, President Donald Trump signed executive orders reducing Utah's Bears Ears and Grand Staircase-Escalante national monuments by approximately 90%, shrinking their combined area from over 3.2 million acres to under 303,000 acres. While Utah Republicans and Governor Spencer Cox celebrated the decision to open lands for potential mining and development, tribal leaders like Davina Smith-Idjesa condemned the cuts to sacred ancestral sites. The move is expected to trigger major legal battles over presidential authority under the Antiquities Act.
