Yeehaw! 🤠 Our team saddled up for a Spirit Wear Day to mark our 36th anniversary with a Western-themed celebration across our offices! With most of our work in the West, we wanted a tribute to our roots that included a little giddy up.
Thank you to our Admins and Corporate Services Group for wrangling this rodeo. Here's to many more years ahead! 🐎

"The Advisory Council on Historic Preservation recently approved sweeping revisions to the regulations that guide Section 106 review. Preservation organizations, Tribes, archaeologists, community groups and many professionals worry these changes could fundamentally alter how Utah’s cultural resources are considered during federal decision-making."
Voices: The quiet process that protects Utah’s heritage is under threat “The buildings, archaeological sites, cultural landscapes and places of significance to Tribal Nations protected through Section 106 are not abstractions,” Brandy Strand and Tina Hart write in an op-ed. “They are part of our communities’ story.”
✨A moment of Zen from one of the last weekend adventures of this summer. Have a great week everyone! 🍃
