Senate Budget Bill Proposes Massive Sale of National Public Lands | Grand Canyon Trust
Up to 120 million acres of our public lands could be available for sale. If that happens, hunting, camping, birdwatching, and hiking opportunities would be lost forever.

Western voters overwhelmingly support keeping national monument protections in place, and ensuring Tribal Nations help lead the care of their sacred places.
→ 88% support monument protections
→ 83% of Republicans, 87% of Independents, 97% of Democrats
→ Even 4 in 5 MAGA voters agree

National monuments are hugely popular with Utah voters, yet here we go again with attacks on OUR public lands:

Trump may shrink 2 Utah national monuments to expand mining and drilling in the West, per report
After declaring a national energy emergency earlier this year, President Donald Trump is looking to roll back federal protections to promote energy development.

An audio piece I made for a video by Fazal Sheikh showing methane leaks at oil wells in UT and AZ. I recorded ground vibration at several pumpjack sites then sped these up and combined in a 10 min loop. Rather proud of how it turned out (pumpjacks): geohazards.earth.utah.edu/exposure/
